2 Truths & Trash Playlist (All Episodes): • 2 Truths & Trash
Here's a list of questions that will be answered in this video:
- Does rubbing a magnet on a screwdriver magnetize it?
- Does adding paper towel strips to an ice cube make it stronger?
- Does rotating a coin around another equal sized coin cause it to rotate once?
- Does blowing air into a straw cause the water level to rise?
- Can you de-magnetize a screwdriver by dipping it in water?
- Does cacao powder remain dry when dipped under milk?
- Can AA batteries be used to power a typical lightbulb?
- Can the lip on a jar assist surface tension in holding water in the jar?
- Does paint mixing work in the way described? - Věda a technologie
For the past several months, I've been working on a new series for my channel as well as my first physical product based around the concept of 2 Truths & Trash. I'm super excited to share more about both in the coming weeks. Thanks for watching!
Super excited to see it all!
same
I see
I was like, water can't do that Then im like the paint dont work that way
For me it was like this:
Batteries - Immediate bullshit
Jar - Hmmmmmmmmmmmmmmmm... I know of this trick...
Paint- Wait a minute, that's not how paint works
For me it was like this:
-This seems slightly fake but I could see it being real
-This one is the fake one, water cannot physically float that way
-That's not how paint works and it's obviously edited, this is faker than the last one so this must be fake
I was like "Well the circuit isn't complete you gotta connect up the other side of the lamp to the other side of the battery!" and then "PRETTY sure water doesn't do that..." and then I'm like "Aight paint doesn't workt hat way"
Here I'll join in.
Batteries: Fluorescent bulbs don't work like that and where's the ground/neutral? I do know they light up from having certain things near them though so yea fake.
Jar: I know this does work but that jar seems awwwfullllly wide and don't you need a card? But the battery one is fake so I guess this one is real?
Paint: Err... no? What? Is the battery one real???
Even though I was expecting to get punked on the final round, I still thought the jar one might be legit... Happy April Fools' Day from a fool!
Same
Cause he pulled off the same trick in a previous two truths and a lie video
I mean if you have a small enough jar, it would work.
i'm pretty sure the jar thing does work, but not in exactly that manner. iirc, you put a card/paper on top before flipping and then slowly slide it out of place. i think? i'm positive i've seen/heard of it before...
@@ETXAlienRobot201 it doesn't actually work if you just pull it out, but you can get a thin, clear plastic sheet over the top with some more rigid material for while you turn it upside down, which you can then remove. The opening can't be too big though, you can't have too much water, as it will make it too heavy, and it works best in contact with glass if I'm not mistake. A thin mesh is also able to do the same thing.
4:39 not only does it show that difference between additive and subtractive mixing it also shows that most of our used pigments are not pure in color.
Bro droped this in april 1 and thought we wouldent notice
Edit: i thought it was a normal video when i wrote this… 💀
He dropped it on the second
@@randomname9291it says “April 1st 2024”
@@UncivilArchitect it says April second for me, might be a time zone thing
@@randomname9291 I guess so
bro didn't watch the whole video 💀
I figured the ice would be stronger with paper towel inside likening it to fiber reinforced concrete. Magnetizing screwdrivers has been a trick forever, the hardware stores even sell little coated magnets with a hole or groove to make it fast and easy to do.
Look up "pykrete" if you want to learn about the funny military version of this, a mixture of ice and wood pulp, which takes considerably longer to melt and is far stronger than just ice. During WW2 the Brits proposed building an AIRCRAFT CARRIER out of it, Project Habakkuk. A completely unhinged plan on every level which I very much recommend the wikipedia page for. It's totally nuts, but in that wonderful 'British military researchers during WW2 collectively having a long series of Jimmy Neutron brain blasts' kinda way.
i didn't know mixing paints was "subtractive" or light being "additive" - this makes SO much more sense for image editing, addition filters & subtraction filters.
i knew there was always a difference, but i just called the differences light vs physical.
It's been some time, but I still got it in me!
Quick reasoning for 3rd round all wrong:
1- The circuit isn't complete, both sides of the battery need to touch the lamp to complete a circuit and generate electricity (creative one with the plasma globe, I thought it was just clever editing)
2- Water surface tension is extremely strong, yes... But just for very small areas. The lid is too big, so I thought he had done some clever editing yet again, but a fine enough mesh does work.
3- Any kid ever knows this one is wrong. Also, those aren't even RGB! That's yellow there!
Technically the true primary colors of paint are cyan, magenta, and yellow, but even so that's not how subtractive mixing works.
Ah yes, the primary colors war that triggers everybody who works with different sources of color...
green isnt a primary colour, its made with yellow+blue
monitors use RGB (red-green-blue) probably because human eyes are extra-sensitive to the colour green, so without a dedicated green light it would look too washed out i guess.
@@wojtekpolska1013 Green is a primary color of light. It can be made with yellow and cyan (not blue) paint.
@@wojtekpolska1013 Please don't try to explain how monitors work when you don't have a good understanding of color theory.

I forgot the answer, time to watch that veritasium video on this
babe wake up a new 2 truths and a trash dropped
It just happens to be April fools when two Truths and trash becomes no truths and all trash 🤔
I got all three on the last round before realizing it was an April Fools prank. You did a good job with the distraction.
You know, depending on the metal of the screwdriver, putting it in hot water might demagnetize it. Magnets break if they are heated to their Curie temperature, and for some metals, this temperature can be pretty low. Gadolinium can lose its magnetism just by holding it in your hand, while Iron can break down with a blowtorch.
You got me on the last round!
The lightbulb and mesh trick reveal was shocking in its own way. You certainly would’ve fooled me if it was a regular video
You know you can also demagnetise a screwdriver by hitting/tapping it against something.
Round 1: C. Depending on your perspective, the moving coin either makes 2 or 3 full rotations. I remember Veritasium doing a video about this. (Ha! Cool to see you reference that same video)
Round 2: Let's see, I know that cacao powder is hydrophobic, so C checks out. A is a little weird, but it also checks out because those bubbles cause pressure to build up in the air pocket of the bottle, so when the pressure from your mouth is removed, the pressure inside the bottle is greater than ambient, causing a force on the water. So just by process of elimination, I have to go with B. (Cool, got it right. Honestly surprised that rubbing the magnet back on it worked, though. I would've just expected that to invert the magnetic field)
Round 3: I know this isn't a listed option, but all of these have to be fake. For A, the batteries are only touching one of the bulb's leads, so there's no circuit, and therefore no current. I suspect there's some masking trickery going on there. For B, that lip is not enough to create the necessary surface tension. You would need some kind of mesh, which I suspect is what he used. And C would not work because mixing paint is a form of subtractive color mixing, meaning that mixing the primary colors of paint creates black. Knowing that makes it obvious that there's some kind of digital color manipulation going on. (Called it! Though I was surprised by the plasma globe, and the fact that the paints actually made a purplish gray.)
The fact that you didn't show the actual coin rotating in the last video, and instead showed an animation of it, gave it away.
The last one was interesting me. While i do know that mixing colours in paint is not the same with light, I had always wondered why/how they could be different.
paint averages, while light adds.
Paints and pigments absorb light, then reflect back the colour you see, so as you add them together you're absorbing more and more light. The mixing of blue and yellow paints to create green is actually subtracting everything that isn't blue and everything that isn't yellow then adding the results together which is perceived as green.
Which poses an interesting question, if yellow and blue pigments make green, how do screens with only red blue and green emissions make yellow? It's because emitted light is additive, so you need to remove the blue from green to make yellow, but since you only have the three primary colours to work with the best thing you can do to remove the blue is to add red.
Since light is not only a particle but also a wave, the waves of red and green light create a new wave peak though constructive interference in the middle, which depending on the intensity of each source could range from pure red, to ocher, to orange, to amber, to yellow, to lemon, to lime, to neon green, to pure green.
Love the quick explanations and the shout out to veritasium
2:22 The coin one. It is actually 2 full rotations.
I'll go with B, the cold water one.
And for the last one...C. Mixing the colors as paint will get you black (or a very dark brown) not white.
Gg I was so stressed on that final round.
I love this seri
Round 1 I got right because I knew the paper was going to act like rebar and knew the first one was real. Round 2 I got right because number 2 isn't how demagnetizing something works. And then round 3 I knew the first one wasn't how electricity worked, the second one didn't have enough matieral for the surface tension to hold back the water, and I didn't pay attention to number 3.
I never expect the "All are fake"
What speed cube screw driver is that
First one i did flawlessly!
The first one is obvious because it is the only one he had to animate. I do actually know why, but still.
Round 2 seemed pretty obvious, no problems there
Round 1 threw me in a loop because I was 100% confident that you can’t make ice stronger with just paper towels, and I thought he replaced the ice with something else
Round 3 I suspected that the first two were fake, but because of the one-fake only system I have been used to and my brain suddenly kicking into action with the “you can’t make white paint using colors” knowledge from my childhood, I was sure that the white paint trick was the only fake.
I never thought I would be fooled as a young adult on April Fools Day 😂
Yay, I actually called the last round!
In the first one, the circuit was not closed, so there was no way the bulb would turn on.
Second one I wasn't entire sure. I know it can work sometimes, but only if you have no (or very little) air in the glass. And probably only with some sheet of paper over the opening. I thought this much air would make the water spill. Still, you tricked me, I was expecting some editing trick, this method was much nicer.
Third, I know just enough about graphics and editing, that I recognize that light and paint works the other way.
Undefeated, the April Fools doesn’t count
First time I ever got them all right. Last round had me second and third guessing myself but I stuck to my guns.
Was really excited to try out #2 in the final round until #3 played. Man...
i think the hammer bent when you hit the tissue ice
Popped off today, I gpt every round right
round 1: i chose 3, explanation, 1 and 2 were obv correct
round 2: i chose 2, explanation, 1 and 3 were correct as i know what's pressure and that cocoa powder is mostly hydrophobic
round 3: i chose 3, explanation, it only mixes white in light theory, not color theory.
Jokes on him i watched the coin rotation video long before😂
First Question: Magnet one makes sense, for some reason, in the past I froze a wet paper towel and it was very hard, and the 3rd one was suspicious so 3rd
Second One: Chocolate power I think is hydrophobic, 2nd doesn't feel right, and 1st feels fake, I'm going for APRIL FOOLS! (I was wrong)
Third One: 2nd one is fake, 3rd is fake, and seriously, it wasn't even connected. This one's the All of the Above
Welp - I got every round wrong.
Got them all, but even after watching the Vt video, the quarter thing still hurts my brain...
I thought that it was the colour one at the last but everything made no sense
questions about your work on this one was the only thing we i have been in a bit of a few days ago and it was great to see what I want to go meet up with the following is a great time for the role and the other thing that is not a problem with the job requirements for this week
I’m confused what’s the real primary colours? I was told it’s red green and blue but in this video it’s now red yellow and blue.
Yo the last one 💀💀
Of course its on april 1st
Pls post more often!!!
Very cool, though I've got to say the last one with the jar wasn't very clear. I assumed you had the mesh on, because most jars don't have a special "lip" that'd just be around the circumference. The mesh was pretty clearly there, and I had already known about this trick.
Nooooooo you got me, i whas so confused cause both b and c from the last felt fake, but i thought a made sense
Tho, now that i think about it, it doesnt
0:58 I studied this in school lol
Who else knew about the ice from mythbusters?
Woahhhh but this is on april fools
Damn, I got fooled on tound three
Polar water molecules lol
Yoooo i changed the likes from 999 to 1K
1) all were truth 2) C 3) all were fake
Boy these ones are easy so far, as option c just looked fake, on the 1st option, and I know that option b doesn’t work like that, edited due to watching the video more:
of course you would pull the multiple wrong option on April fools day, you showed us a way how option b could work but I got still got fooled by that, I knew option c was wrong, and I admit I never tried option a
I was taught in school that red, yellow, and blue were the primary colors, and could be combined to form the other colors.
Now I’m told that the primary colors are 𝗻𝗼𝘁 red, yellow, and blue, but some other colors including “cyan.”
Can somebody please explain?
For light it's red, green and blue (rgb). For paints it's cyan (blue-ish), magenta (red-ish), and yellow (cmyk)
They're cyan, magenta, and yellow, which are the inverses of red, green, and blue, respectively. So mixing cyan with magenta mixes the inverses of red and green, leaving only blue. It's a common misconception to say that cyan is blue-ish and magenta is red-ish, since cyan is as close to green as it is to blue and magenta is as close to blue as it is to red.
@@joshix833 Where does red, yellow, and blue come in?
I got fooled
People who think purple toothpaste will whiten your teeth should be sweating at that last one lmao
New Video!
A. It's not NeodyNium.
Everything from the 3rd round was so obviously fake but at this point there is so much bs to this series that i believed atleast one of them was real (also am i the only one who failed the color thing? Considering everyone else said it was "obvious" i feel like an idiot now..)
Doorknob
Thank fuck I got all of these (I study physics)
I will not be japed so easily
Round 3: E - Multiple were fake.
My bets on everything or nothing is true
I win!
OMG i actually got all right. I told myself as a joke „all fake“ for the last one
B
c is fake
