- I recently found copper listed on the ingredient list for some candy. Can that really be true and are any metals allowed as a food additive?
Join me in a journey into some odd food additives and drinks in this video. Including one that is about to get banned in Europe!

I never understood people who pay extra for unnecessarily expensive gold leaf food at "luxury" restaurants. It's just dumb.
How else do you flex your flakey ego!?
It does not make much sense to eat gold. You might as well directly feed the rats in the sewer with it ;) Though, the actual amount of gold in gold leaf is very, very little. Milligrams at most. Thanks for watching!
@@brainiac75 Yep, most people could afford to eat gold-leaf food daily at home if they wanted to!
And the video was great.
Yes...but...golden poop..
@@106640guy Maybe even golden corn!
I don't like that Aluminium is allowed , I saw the congressional hearings on Aluminium in food , on one side you had a group of scientists saying it looked pretty bad , on the other side you had a group of Aluminium industry lawyers , the lawyers won , but I was not convinced.
Yeah, I was surprised about Aluminium too, it seems to come up in conversation about Alzheimer's quite a lot.
it's not just allowed, it's basically impossible to get rid of. You don't have to worry either way, there is no good evidence that shows a causal relationship between aluminium exposure and alzheimer's. That doesn't mean it doesn't have health risks if you ingest too much, but if that specifically is your concern, avoid heavy metals like lead and manganese. Again, you can't avoid them entirely, but the body can deal with low doses of metal ions just fine, thanks in big part to a glycoprotein called Transferrin, which brings them to your kidneys to be expelled
@@snowthemegaabsol6819 What's amazing is that vaccine for Alzheimers is being developed. Which means much lower risk of that, AND alum has no role in it.
@@XXCoder, post nose.
Most vaccines contain aluminum, and mercury.
I drank a lot of Goldschläger when I was a student in the early 2000s. I often wondered what happened to all the gold I ingested. I guess it just became suspended in my poop, and then evacuated, for someone to pan out of a river in a few 100 years time.
Fiber?
They've ptibably actually ended up in the sludge that wastewater processing facilities generate... It could be in someone's flower bed :P
Depends on where you live. Some places have found it economically advantageous to refine gold out of sewage.
Yep. You had gold-flecked poop. That's it.
Given the tendency of gold to drop out of a flow of water, you may very well have some still in your tummy.
Yesterday I went to a vintage laser and hologram museum, and I was thinking of this channel the whole time
Where is that? Sounds cool!
Ngl "vintage laser and hologram museum" makes me feel old 😓
wtf is a vintage hologram
one of a few channels on youtube where barbaric dislike removal wont affect my viewing experience at all, because you always deliver quality content.
True!! but anyway... 44 dislikes as of now.
It shouldn't affect your experience, drawing your own conclusions is the best way to go.
@@classicallibral5903 it just says “dislike” for me ( mobile ), but no count for some reason
@Tungsten Dioxide then where’d the 44 come from? Does it only show dislikes on the webpage?
@Tungsten Dioxide thanks for letting me know
When the bottle stops spinning, the viscosity and the distribution of metal flakes (and thus the density) are not uniform throughout, so there are going to be 'discs' with more metal flake concentration that want to maintain rotational momentum more than the neighboring more viscous 'disc'. Once that gradient exists, metal flakes gravitate towards the discs with higher momentum and lower viscosity, so they clump together into the visual effect we see..
...
...
...
But I have no idea, really.
this was similar to my guess i think the metal is in a suspension and cant overcome the fluid viscosity untill its spun around but then it has more interia and concentrates into bands because its essentially "spooling out" ?
@@Valet2You have successfully made an innocent man fear the chair
I was 100% in agreement with you until I saw the horizontal test in the bowl. If the metal flakes form a region of higher rotational momentum, seems like that should mean we’d see metal force its way to the outer edge of the bowl when it stops spinning. That doesn’t seem to be happening, though. If anything it seems to collect at the center.
Perhaps the glitter forms a region of LOWER density? That could potentially produce both the banding (if your basic explanation is correct) and the collection of glitter at the center.
This is the same principle as a hydrocyclone or centrifuge operating in a gravitational field. The metal particle size distribution changes the point in the fluid they sit at when they are spun. They have different masses. They all have a downward acceleration due to gravity, but when you spin it sideways the particles are pushed outward and if you spin it fast enough you can overcome gravitation. As it spins down the particles arrange themselves into bands as similar sized particles fall at the same speed.
@@cavemandanwilder5597 how do you know that horizontal bands weren't forming in the bowl? We have no way of seeing.
The stacked donut torus flow in the cylinder is known as a Couette-Taylor reactor. It is mathematically significant as a case of non-linear fluid dynamics used to study chaotic fluid flow.
Thank you! I'd just noticed this effect the other day and it was driving me nuts. Wild synchronicity for me to land on this video...
@@rosonowski CZcams reads your mind
Thanks, I've been scrolling comments just to find the answer to this!
I thought that effect looked familiar, but I was clueless why. Once I read your perfect description, decades-old memories flooded back "Oh, yeah!" Thank you, sir!
I think its something about the particles basically acting as denser fluid and want to keep going, so follows the path of least resistance, which happens to be the 'wake' behind more particles
Also over a hundred years ago during the great Australian gold rush ingesting gold nuggets that were not too big was a common method miners would use to illegally sneak gold out of the gold fields so they didn’t get a significant amount of it’s value deducted in taxes when selling it to the government.
Panning turds....
@@lindboknifeandtool
That’s what they might of done in their buckets as they did not have flushing toilets at the time! :)
When he stopped the bowl from spinning, did anyone else immediately think of Jupiter's red spot?
The best part of your videos are the fact that your don't just put "Don't try this at home" you take time to tell people the exact dangers of chemicals you use.
I do a lot of cake and cookie decorations. The info about gold leaf is very interesting.
Edit: also good news: Titanium dioxide is mainly used as a whitener/to give things opacity and a natural white coloring. So its not the worst thing to be banned as there are other options. It DOES pose a real threat to coral reefs though from its usage in sunscreen.
What are those? It's the most common n probably cheapest white pigment.
Not regular TiO2 - only nano. The big chemical offenders to coral reefs are Oxybenzone, Benzophenone-1, Benzophenone-8, OD-PABA, 4-Methylbenzylidene camphor, 3-Benzylidene camphor, nano-Titanium dioxide, nano-Zinc oxide, Octinoxate, Octocrylene
the reason you get bands in the glittery drink is probably the same reason you get banding in rings around planets. it has something to do with conservation of angular momentum combined with chaotic collisions of particles. any cloud of particles that is rotating will eventually result in a flat disc of bands due to the collisions of particles against each other
good, but it more like whirl pool, sialon (twister), in a bottle, so the force line is going top to bottom or botton to top, in the bottle?
The copper is a terrifying prospect.
Gold is a hilarious prospect. It is literally one of the most inert substances in the universe. It quite literally can't do anything inside your body
Gold can do bad things however your body has a hard time to absorb it
I wouldn't want to eat it with every meal. A gold deposit in the intestines could cause serious mechanical problems.
@@iainclark8695 why would it deposit instead of being evacuated from your ass?
@@LinkinPark4Ever1996 For the same reason panning works: it's heavy and thus collects in low points
@@magnuswright5572 Thanks buddy. Have a great one!

Of course he spits it out! It’s LICORICE.
@@marialiyubman but licorices are delicious, then again I am Swedish sooo...
🤣 haha hah! Yeah, I'm eating candy yuk! I'm spitting out copper. And I thought copper was a semi precious metal!
The red fluid in the bowl reminded me of a museum exhibit about Jupiter’s clouds. They used a similarly glittery fluid to represent the gas. You could spin the sphere full of fluid, and I assume it would make bands like in Jupiter’s atmosphere. I was too young to remember it, though. I have also seen other exhibits using glittery fluids, but I thought this would be the most relevant.
3:48 I see it as a rheoscopic fluid-perfect to geek out over the Navier-Stokes equations!
Ah yes, it does have some rheoscopic properties. The vortices formed when topping off the plate are just beautiful 😊
Titanium dioxide is in many medicinals, such as toothpaste and as a filler for tablets. I wonder if they will be banned there too.
Seems weird to ban it from food, but not medicine.
TiO2 is not used as filler for tablets, it's used in the coating of the tablet. TiO2 is used as a food die, it's white paint. "Medicinals" as you described them are not medicine. Toothpaste and vitamin pills are under food laws in Europe, TiO2 will be banned from them. Your toothpaste and vitamin pills will no longer be the same shade of white. Perscription medicines are under a different set of laws, so I don't know if it'll be banned from medicine.
@@ivo215 If I understood correctly they will be banned from medical products, but bit later.
What about suncreams?
@@stefanmayer444 sunscreen usually isn't eaten.
@@95rav Am I the only one eating it? ;-)
Sure, but is skin contact defently not harmful? I thought titanium dioxide would be save for consumption, now it's determined it's not, so I'm wondering if that's the case for the skin as well.
Hello! It's gratifying to see you cover chemistry content again!
Someone is going to have a hangover after Christmas...
(And a sparkly toilet bowl!)
I went to show my kid some of your videos on magnets but was using the YT kids app. When I searched for your channel and videos nothing came up. I even tried using direct URLs in the search and that didn’t work either. So I tried other channels that are dedicated to science and the vast majority of them wouldn’t come up or only small clips posted by other people came up. So it seems that YT considers a lot of scientific content not suitable for children, which I can understand some scientific topics wouldn’t be but what I was searching for is a bit much in my opinion.
I only let him use that app since it’s very easy for me to heavily monitor and sensor it. He is still under 10 but since I do a lot of different things in my workshop and electronics lab, his interest’s are not typical of a child his age. I try to nurture any interest (especially when it comes to engineering, science and technology) he has as long as it is not dangerous or obscene for his age.
I do find it ridiculous that this channel, Nile Red and many others in this sphere are restricted on the kids app. Unless I’m doing something wrong, this seems a bit ridiculous.
It's because it allows comments.
He has to specifically mark his channel as for children.
for 2 reasons, one, chemistry and science are often dangerous. and two, when making CZcams videos, you can either make them "for kids" OR "not for kids" there are no other options. if you select "for kids" it will get a fairly small adult audience, so mostly just kids. and I believe it will not allow comments. this is very impractical for a thriving CZcams channel that gets lots of views from adults. I would have to say that this is CZcams's fault, its not providing any other options.
@@Metal_Master_YT It would be really nice if there were an "educational" flag, for content that you want comments for adults to be able to see, but is intended to be kid-suitable as well. It's strange to me that comments are disabled for adults viewing content intended for kids- All that does is incentivize creators to not flag their content as being for kids, leading to the only people who make kids' content being intended for one-directional communication.
@@weeveferrelaine6973 yep.
5:37 gotta love Brian waving in the reflektion of the gold
E171 Titanium dioxide is a very common die, used in foods and paints. It's white and opaque. If you buy a can of white paint in the hardware store, the white color in the paint is TiO2. It's very common in foods too, mostly because it's opaque. It's used to mix with other dies to create almost any opaque color. The ban does come as a bit of a surprise, because it's so common in foods, and it has been for years and years. I work in the food supplement industry (vitamin pills), and using food dies in a product that is intended for your health has always been controversial. But most companies that sell food supplements prefer their pills to look 'neat' and have their pills coated with a coating containing TiO2. The pills are painted white, or another color while still containing TiO2. The coating does also serve to improve shelf life and make swallowing pills easier, but that can be done without TiO2. It really is there only for the looks. I guess pills are no longer going to be coated white.
Just go back to lead carbonate
@@RobertSzasz I don't know what lead carbonate is but the first word alone tells me it's not safe
@@piisfun Carbonates are inorganic for historical reasons but for example tetraethylead is not. And the distinction organic vs. inorganic doesn't make a substance safe or not. You can not survive in pure nitrogen, eat 100g of NaCl at once or some cyanide salts. But on the other hand organic substances like proteins, fats and sugar are part of your daily life.
Apparently, TiO2 is getting banned because currently they couldn't conclusively test if it causes DNA damage and because of no way to test it they couldn't establish a safe dose of it.
@@shepardpolska it fucks up your gut flora, tests have shown IIRC. Especially nano particles of it. So while we might not get directly get harmed, we are getting indirectly harmed as we rely a lot on our gut flora.
Stumbled on this video and this creator is easily worth a subscribe. This video was fascinating and informative, I was hooked from start to finish. Great work and I'm looking forward to watching more!

Scotland has fizzy drinks called Ironbru, it contains ferris sulphate.

Huh, never heard of that. I guess most countries have some unique drinks only sold locally. I think the Glitter Fisks featured in this video are mostly a Danish phenomenon. Thanks for watching!
That banding effect is awesome, it looks like Jupiter in a bottle.
Another quality upload from my favorite science channel! Thanks for the wholesome content, Brainiac!
4:50 imagine doing this in ancient Rome, Greece or Egypt, you'd be heralded as an alchemist, magician, prophet.

Brainica after the video: "It's drunk time baby!"
A few years ago I found an old jar of silver bead cake decorations in the back of the cupboard. I recovered and refined the silver and managed to get just under 1 gram from a 250 gram jar so actually a rather high percentage by weight. I was very surprised and still do not believe eating any amount of pure silver could be a good idea.
But don't you want to get argyria? Just think of the dashing blue-gray shade your skin will get and all those high status medical issues you will get! It's totally the modern status ailment equivalent to gout in the medieval times when only rich people could afford to get sick with it...
I doubt that you would actually get enough silver to hurt you before you started turning purple-blue.
All sources I found say that despite coloring your skin blue if you are exposed to large quantities over long time, silver doesn't do any actual harm to you.
@@Szoki86 in a minority of cases silver consumption can lead to organ damage and seizures. More commonly, "interact with prescription medicines, including penicillamine (Cuprimine, Depen), quinolone antibiotics, tetracycline and levothyroxine (Unithroid, Levoxyl, Synthroid)."
@@Call-me-Al ah, so this isn't a case of "you shouldn't have silver because it hurts everyone universally" it's more like "you shouldn't have silver because you don't know if you're within the demographic it will hurt, and there's no benefit to make the risk worthwhile"
Excited to watch as always! Your videos are beautiful 😍
Glad you like them! More videos about the fun and beauty of amateur science coming up 🤗
@@brainiac75 Thank you for promoting science in such a wonderful and accessible way that can truly be enjoyed by all. This video was great as always 👏
You could have done an acid test for the gold. If it dont dissolve in hcl or h2so4 its likely gold.
Amazing video again, also that with the patreons it is all cool and very well made and interesting.
Thanks so much. It's so coincidental, I was just wondering about this exact issue when using some metallic sprinkles.
The vortex formation is very similar to the Taylor-Couette flow en.wikipedia.org/wiki/Taylor%E2%80%93Couette_flow, plausible that the same flow instability takes place here. (3:11)

I wonder if the banding at 3:00 is the same phenomena that explains the planet Jupiter's bands
This video was so beautiful, I loved the pepper thing that left those trails and also the vodka with the non floating gold leaf
This was really visually pleasing to watch
It's going to be difficult coming up with a clear/semi-clear cocktail with such an earthy spice like turmeric that will taste good.
How bout a earthy tumeric milk punch cocktail with chartreuse or something similar. I think the milk punch process would clean it up. Just an idea though.
Turmeric and orange juice are actually not bad. May be a spiced screwdriver would be good?
(I use the orange juice to mask the flavour of one teaspoon of turmeric and drink it to help reduce swelling when I over do it and my knees start to swell, works great!)
Regarding the bands formed in spinning fluid, there is some amount of research about it and you could find videos regarding the topic. But, congratulations, you just made Jupiter. (Research is focused on why Jupiter's (and other large gas planets) atmosphere is banded such as it is, and the physics involved with spinning masses of fluid)
Great video all the same, not what I expected you to put out!
Not sure if this might work, but gold should weld to itself "easily", so if you separate all the pieces, and press it together, if it is gold, it should weld, otherwise might be not gold. Not sure how much oxide it might have due to being submerged in ethanol and water.
Only pure gold does this, even just tiny bit of contamination prevents the weld.
Gold doesn't react with oxygen so it shouldn't oxidize.
i love this channel!!!
But aluminium is still okay? That be the one I'd ban.
No use. Every vegetable you eat is still full of aluminum compounds.
And then also ban aluminium foil in food preparation like baking and grilling, sometimes the food doesn't come clean off...
Lobbying from the aluminium and food industries. Not because they want to add aluminium, but because of the constant contamination from aluminium components and packaging.
4:58
Kurkumin is extracted from roots, its kind of safe. We use it everywhere here, I didn't knew it made such amazing colors on UV.
2:56 beautiful Taylor-Couette flow!
I remember the first time I saw titanium dioxide on an ingredients list. My instant thought was "that cannot be safe.." So I did some internet searching and from what I could find it's considered "mostly safe." Doesn't make me feel better
Why? By all reason it should be remarkably inert.
@@SianaGearz Theoretically it is, however I it's still a bit unnerving.
TBH, I am more worried that pure Al is considered safe
It's pretty much just sand. It won't harm you.
The ban might be reversed as the reason for it is that they couldn't rule out it causing DNA damage and couldn't establish a safe dose, so the ban is just in case seems like
Merry... Early Christmas Brian!
Same to you! Though a little too early for my liking. Apparently I will be hit by a snow storm tomorrow...

Your voice is nothing short of delightful to listen to. :-)
a beautiful video: thank you very much!!!
Licorice isn't healthy in large quantities either. Chubby Emu did a video about somebody who ate a lot of it. It didn't end well.
I mean. Water itself is toxic in vast quantities.
We only have fake licorice allowed in US
But hangon, isn't titanium oxide used everywhere as "white" in pretty much everything? That sounds like a very big ban!
Never let reality stand in the way of politics!
yep, the opacity is very useful and a ban sounds shocking
Yup, it is gonna be a huge effect. It's used to turn things opaque and make bases for almost every other colour. I am sad that such an incredibly useful product turns out to be bad, but if it is then it is.
I don't really care if the food I buy won't be as white. Hell, I WOULD PREFER not having any questionable chemicals in my food, toothpaste, or other products. I don't want to take risks for some stupid reasons I have no control over.
They're not Banning Ti oxide, they are banning From Food! ...and yhen I saw your smily face! 🙂

Great video again👌
Thank you, Legend! More to come.

hey brian, what wavelength of uv light will u recommend for checking general fluorescence or which one do u use?
Hi. The shown flashlight in the video uses 395 nm LEDs. They work great, but 365 nm can be used too and will give off less visible light, making the fluorescence perhaps stand out more. Even a 405 nm laser will work for general fluorescence. Search for an UV light meant for finding amber. They work great and are inexpensive. Thanks for watching!

I'd guessed aluminium because of it's possible link to Alzheimer's.
Anyone else heard of this? Even though we use so much aluminium foil & cookware.
Maybe it was one of those outlying studies. I should go read up...
The Alzheimer's society says that no link between aluminum cookware and alzheimer's exists.
When someone has alzheimer's they have excess aluminum in their body, but there is no scientific reason to think that aluminum exposure causes it, more that the disease causes aluminum accumulation (or something).
@@renevile Correlation does not imply causation, as they say!
Vaccine for Alzheimers is being tested now. Which is an amazing news, and you can't make vaccine for aluminium.
@@XXCoder Just like you can't make a vaccine for smoke. You can however put heavy smokers on a precautionary chemo therapy to significantly lessen risk of cancer.
So still aluminium could still very well be a part of the puzzle and the higher levels the higher risk of alzheimers.
The aluminum-Alzheimer’s thing was debunked 25 years ago.
for why the bands in the liquid, ask Jupiter.
The contact with the bottle and the non perfect shape makes small difference in speed, these are increase until they create proper layers.
Jupiter was my first thought too ;)

Excellent video thanks
Very cool. Thank you for sharing :)
As for the rotating bottles, I think its probably the momentum of the fluid because of the rotation, the bottle stopped but the fluid inside is a separate mass (and obviously) is liquid so it won't stop as fast as the solid container.
Kinda like why if you spin around yourself and then stop you'll feel dizzy, the fluid in your balance organ in the ears continue to spin, causing mixed signals that confuse the brain.
Unrelated: I really liked the background music in this video :D
That don't fully explain the swirling glitter effect though - but is indeed a part of the explanation. When the container stops, the liquid next to the glas surface stopps before the liquid further in (due to the friction/adhesion), which causes small wirlpools to form inside the liquid - which in turn collects the glitter in some spots where pressure is lower and also makes the particles rotate, creating the effect. In the bowl, the liquid next to the large bottom also slows down faster than the liquid above, causing a different effect.
It's very obvious at 3:50 when i pours more liquid in into the bowl, that wirlpools and high/low pressure zones is creating the effect - because the glitter effect exactly follows the expected current pattern around the stream of liquid coming down.
The question was why it creates the bands not why it swirls.
I was always wondering when Titanium Dioxide was getting banned. It accumulates if eaten a lot in the body, and considering that most food that contain white colouring use it, it makes a lot ingested when eating industrially prep foods
Does it? Haven't heard that. Can tell you I literally turned my tongue white _painting pigment_. No taste. No upset stomach. Nothing.
@@gur262 yeah, but on the long term
What a great video, thanks.
When you stopped spinning the bowl, all of the coagulated stuff looked like organs, to me.
My assumption on why you see banding is that the extra friction from the contact at the top and bottom of the bottle slows down the flow of the liquid allowing the liquid in the center to flow more freely and spin around faster than the liquid at the top and bottom. That's why the bands start at the top and bottom and then only appear towards the center. But hey, I'm just an ordinary plebian, so I'm probably wrong.
The far as i know most of pure metals especially iridium and osmium dangerous because they add you weight
But if serious it's really strange that the most compatible metal has a banned oxide for a human
Great video!
Titanium Dioxide is used in a lot of stuff! I didn't know it could be harmful, I'd expect Aluminium to be banned first.
If you use copper cookware, isn't there bound to be some cooper in the food?
only minuscule amount, probably less than what you would get in the supplements.
@@renevile I don't think so, we also use cooper pipes for water. Almost all hobby grade distillation stations are cooper, BWT filters also contain cooper.

@@Xnoob545 You're mistaken. Copper pipes for water used to be pretty common. Of course, these days, plastics have largely taken over but you can still commonly find copper pipes in older houses.

@@mateuszzimon8216 Well, to be honest, the vast majority of hobby grade rigs I have seen are made from a canning pot. Usually stainless but sometimes aluminum. The condenser coil is usually a copper water pipe though but not always.
Why is Titaniumdioxide (E171) being banned? The only reason that I could find is that nobody can prove that it is safe, but no one can prove it to be bad for you either. The only thing that seems to be of any concern is that small particles can irritate your stomach lining, but that cannot be limited to TiO2..? 🤔
Even food grade TiO2 has some portion of nano sized particles and in some context they have caused genotoxicity. No one knows if that is significant for humans, but it's best to play safe.
@@user255 Right, I saw something about the nano-particles causing problems in the kidneys, also. I got an "invisible" tattoo maybe 15 years ago, TiO2 in the tattoo ink. It's gone now, makes me wonder if my lymph glands on that side are white now. Doesn't mean anything about safety I guess but still, one more thing to avoid, basically.
@@user255 So the size (and being relatively inert) is the issue? I would expect small particles to be present pretty much in anything, additives or not
@@MrCh0o Not just size. TiO2 in nano size does not seem to be inert.
I love this channel.
Yeah with the music in the background, all I can think of is Skippy62able thinking of another food challenge he can incorporate with these additives.
Gold doesnt have any taste and its waste of metal and health, but some millionaires still eat golden foods
Yep, does not make much sense when you think about it. Luckily, gold leaf is so thin that the actual amount wasted is very little. Thanks for watching!
The evidence that titanium dioxide is truly unsafe is weak at best.
The EU, as always, tries its best to regulate things it does not fully understand.
I don't mean to get political but these things should be left to the member states to decide.
I hear you. But it's not about banning something that it's proven to be unsafe. It's about banning something that isn't proven to be safe. A lack of evidence and understanding is reason enough to ban it. The EU food regulations doesn't work on a basis of a blacklist, it's on a basis of a whitelist. TiO2 being banned is it being stricken from the whitelist.
@@ivo215 Yeah but it was already whitelisted to begin with, and it continues to be by the FDA and as far as I'm aware every other food and drug regulating agency in the world. So for them to backpaddle on it like that, I'd expect actual evidence. If there's no reason to believe something's unsafe after it's been used for decades around the world, I can't justify banning it.
This is the EU's ridiculous war against Tartrazine all over again... Aka reflexively ban something just because a bunch of delusional, anti-science hippie-dippy lunatics threw a big enough fit about it... Only for later science to NEVER be able to prove the supposed health reasons for the banning in the first place. They do this absurd nanny state bullshit all the freaking time... No wonder Britain decided they'd had enough of this ridiculous nonsense.
@@Cooe. Yeah I feel like I'd be much more supportive of the EU if it stopped attempting to be a unified nation under one rule and was actually more of a treaty, military union, economic union only as far as abolition of import/export taxes and tariffs go and free travel agreement.
It's attempting to become the US real badly when if anything, that's the US' biggest shortcoming, the federal government. America's strength and beauty is in its states not its huge corrupt unified government in DC.
But then of course, none of this was ever about our wellbeing.
@@TheFloatingSheep Well, I think I'm actually with the decision to ban it. It is a suspected (not proven) carcinogen in case of breathing in particles. And I work with that stuff in powder form every day, and breath it in too. Maybe it's all an overreaction and the stuff is harmless. But as long as that isn't proven I'm glad to not be exposed to it every day.
Brainiac: "What do you see?"
Me: "A rough morning in your near future."
I hear that tune when you showed the toxic metal wiki page, and I’m hit with flashbacks of scp readings and discussions.
It's called laminar flow.
I'll add it probably also has to do with clear liquids and mixing insoluble additives and those being trapped in laminar flow of the fluid it's suspended in. Smarter Every Day did an amazing video on this.
Frankly, I'm surprised that aluminium is allowed . Ti oxide has been used for anything white for so long that is is very surprising that it is to be banned . Someone selling a more profitable replacement?
The report said that their toxicologists cant *rule out* genotoxcity, meaning maybe it causes it, maybe only in certain doses, who knows? They're taking a "just in case" aka california approach to the concern which is a matter of politics at that point.
I have yet to see pure aluminum used as a food colorant, but would love to buy a sample for my 'museum' :) I believe it is banned in other countries like Brazil. I was surprised by the titanium dioxide too. It has always been considered safe for use in anything. Apparently the issue is the ingestion of nano-sized particles of it. We still have a lot to learn about our bodies reaction to nano-technology. Thanks for watching!
@@brainiac75 Is just nano sized TiO2 banned or everything? Nano sized makes sense but this would be also true for everything else like nano sized iron oxides or silicon oxides. I also always heard that titanium oxide is completely non toxic and also not resorbed in the body.
@@GenosseRot Even food grade TiO2 contains some proportion of nano particles. Thus it is banned.
I saw the lines on the palms of our hands, that was amazing to watch.
Nice video mate and greetings from Germany.
