- As always, let me know in the comments if you have any suggestions to improve this series. Thanks for watching!
Here's a list of questions answered in this video:
1. Do storm matches combust underwater?
2. When you drop a slinky, does the bottom of a slinky stay suspended in air until the top of the slinky falls to the bottom?
3. Can you relight a candle using the unburned wax vapor trail?
4. Can a statically charged comb attract the water from a faucet, causing it to bend?
5. Can a hair dryer suspend a ping pong ball in the air? What about upside-down?
6. Does a raw egg spin differently than a hard-boiled egg?
7. Can a ping pong ball act like a cap and hold water in from a bottle turned upside down?
8. Can you pick up ice cubes using string and salt?
9. Does a coin spin once a battery is placed on a circuit of 4 aluminum forks? - Věda a technologie
Now it's become more like trying to understand which video could be reversed/overlaid rather than actually knowing the answer 🤣
I'm learning to mask better, y'all better watch out 😤😤 lol
@@JaDroppingScience bro the edits are so good sometimes i dont notice them
I agree. I had to look a number of times to realize.
These things are seriously fun, though. Keep 'em coming!
@@JaDroppingScience the ping pong ball and hairdryer one was so good, i didn't have a clue
@@JaDroppingScience I have a slinkier so I cheated
1:41 fun fact: if you boil an egg and do this trick, it will not work because the egg is cooked and is now in a solid(?) form, this is a way to differentiate non boiled eggs from boiled eggs, if you ever need to
this is indeed true, they become a solid due to the denaturization of the proteins in the eggs (the string shaped proteins that are neatly packed get tangled and become solid and rigid due to the heat)
If I’m ever in doubt I normally just throw it at a wall, but to each their own
@@erazure. i lovethis
dats crazy
fun fact for idiots.
in case someone is wondering, yes, storm matches* can burn underwater, but the described mechanism of action is completely wrong
*probably not all of them
And they would bubble
i can't seem to find a video about it (underwater storm matches) can you provide the video id, if its on youtube? from nilered i was told about the fire triangle (oxygen, heat, fuel), so how telltale a magical matchstick would preserve all three? (also isn't water inflammable, especially since its a product of burning itself?)
@@helper_bot
Answering in order:
there is a video titled “Matches That Burn Underwater”, don’t know the ID or anything about the content.
The matchstick is coated in a thick layer of oxidizer-fuel mix, and produces enough heat to not go out ( note: there will be no visible flame while underwater, even though it is burning, but there will be lots of bubbles composed of boiling water and combustion products )
Confusingly, “inflammable” and “flammable” are synonyms. The correct word is “nonflammable”
No water is being burned
Combustion products can be inflammable
The ONLY way anything will "burn" underwater when we are referring to rapid oxidation in an exothermic reaction as "burn" is if the material burning has it's own included "oxidizer". Such as rocket fuel or gunpowder or an emergency flare.
@@paulmartin2348 or a storm match
The first one was tough! There actually are items you can buy that will sustain a flame underwater, but usually youd see a lot more turbulence from the heat
I just used method of elimination, because I knew the other 2 was true so it was kinda obvious. If it was a standalone question though I might not have gotten it.
@@TheQuackleDKZ i thought it was going to be a trick question because i knew all 3 were 100% possible, so i chose all 3 thinking the idea was that you're gullible if you believe only 2 are right.
the clue is that there is no bubble formed by underwater flame
Out of each group, I knew for sure one was real because I'd seen it done/done it before in the past.
same
Or is it just because you are a Porygon-Z?
First one was actually the hardest for me, I knew the slinky one was real because inertia is a thing, but the other two both seemed fake. I only got it because the appearance of the flame did not change one bit as the water was poured on top of it, which was a giveaway.
Second one I had seen all those effects before, but the hairdryer one was obviously fake. It does work, but not when the hairdryer is at a 90 degree angle, let alone 180.
Third one was obvious, you can't get power from a battery with only one terminal connected. I was pretty sure the salt ice one was real, and the ping pong ball water one seemed plausible but I wasn't 100% sure.
Also:
For fire to exist, it needs the 3: fuel, heat, and oxygen. Underwater, it can still have fuel, but the water would suck the heat out of the matchstick, and would also need an external supply of O2 beyond what the matchstick or water itself would provide.
@@namelesscage Some fires burn hot enough to cause a leidenfrost-like effect, and can thus burn underwater, and fuels can have their own oxidizers. I was pretty sure that wasn't what was happening here, but the visuals were a more immediate clue to me.
@@Owen_loves_Butters my stupid ass thought the flame was changing tbh i think that's what got me lol
What inertia? Do u know the meaning of inertia, explaining everything with inertia is just stupid.
U should instead see it in terms of kx and mg it will guide u to "why inertia".
@@TechyMage Yes I know the meaning of inertia, and it's not really a thing, but rather a property of any object with mass.
So far I got every challenge of every episode right!
But there have been a few I wasn't so sure about in the past. Excited for more!
As an electrical engineering student I paused the third one and thought "okay let me see if it's really completing the circuit" so I looked at the forks, but then I was like yo.. the positive is not connected to anything lmao
I really like these videos! Short, sweet and engaging!
I was getting tripped up for a moment on the first round, because there are matches that can burn underwater... Then I remembered that fire underwater can't look like that.
I’ve never seen a storm match before so I had no idea if it was 1 or 3
I gotta say a big thank you for makimg everybody think twice when they see random pseudoscience videos :)
Keep it up!!
Got all three, this one was easy!
Same here
This video got me on a nostalgia trip for I found one of the live actions shows I did like to watch as a kid.
Under the Nose, a scientific edutainment show.
Thank you man! It's refreshing to see this kind of content. Reminds me of Captain Disillusion!
Yay I got them! But I have to admit, these ones were kinda hard and made great, good job!
Regarding the toothbrush frequency video, you picked the better clip. The first one was more believable i had to think for a second. The frequecy would make a design but it needs to be more constant than freehanding a toothbrush on a tray. AWESOME videos by the way!
this is a fantastic series
1st one was pretty hard to figure out. Very cool video
I can't tell if these are easy or if I just have that much useless knowledge but I have gotten every one of these right that you have made so far
Smashed it. Got all three🎉
got them all right, the last three were looking pretty tough but that coin thing was laughably unbelivable.
love this series this time i got 2/3
knew all the truths already and guessed how the false ones were done correctly, nice video
Got all 3 this time! Gotta say, I wish I knew how the first trick in the third part works though!
I was divided between the matchstick and the candle wax paper for round one, but I got the other ones right!
The second one was awkward in the sense that all 3 are true, so trying to focus out which was explained wrong is the main game haha
Those ones are the toughest since I like to play high speed and not pause the video to think 😎
Lol
I'm glad my procrastination helped me pass this test
These are really fun
My brother, who isn't very good at physics got all of them correct because he just thought well about it. It would be realy cool to have harder ones !
i like your videos and i succeed in them not because im not gullible, but because i have wide general knowledge
3 for 3 WHOO HOOO I was so scared at the last one but I went with the 3rd option since I know he overlaps stuff now
3/3 correct
The first 2 trios, I've seen the real science before, so even though I didn't think the fake was the fake until later, at least I got it
Third trio of videos was relatively easy, reverse videos can be tricky sometimes but not this one for me thankfully :)
Big brain move to slightly shake the battery when picking it up, because that's what it'd look like when put in reverse XD
in this video it was pretty easy to see edited footage / backwards footage.
I'm proud of myself for not only identifying which were fake due to an understanding of physics, but also spotting the details in each of the fake ones that gave away their fakeness (lack of movement on the flame of the match when it supposedly came into contact with water, inconsistency in the movement on the ball compared to the angle of the hair dryer, and just recognizing that the coin video was reversed)
i mean to be fair water proof matches to exist u just didnt use them
#3 is a hard one between #1 and #2. The ball will act as a cap, however not under the pressures given, since there's a higher pressure on the inside against the ball than on the outside against the ball in the time of the doing.
Ice will melt when salt is added, so idk how this would make sense, unless it melted and then re-solidified.
Anyways I think its #1.
I was like really conflicted between the match and slinky but i ended up going with match because if you know just a slight amount about fire you know it cant burn without oxygen
Nice got them all right
all those years of watching science related videos have led up to this moment
The first one is correct only on technicality. Because you say it does "nothing" to the burning.
But it does keep burning under water
i was thinking the matches were coated in some form of a magnesium powder. i think magnesium can burn underwater right?
1:00 But couldn't a match like this be done if you have a layer of oxygen enclosed onto the match to sustain the fire effect temporarily under water?
watching those "magic" videos as a kid finally payed off
I knew the one with the spinning coin was fake because no US currency besides steel pennies are magnetic, a dime was used, which is usually made of zinc and copper alloy.
I still can't believe how 3:1 is real
Round one:
“Hey if we’re underwater how can there be a-“
-Patrick Star
Got all right 😊 3/3
underrated
The lack of refraction gave away the first one.
My childhood obsession of simple science experiments finally paid off
Dude the first one all three *CAN* work. They make matched with oxidizers that burn underwater.
Let’s go! I got them all right!
1:20 my brain started questioning everything when I saw this
1 out of 3 lol
I assumed the first one was a trick question
Absolutely loved this video, but how tf does that ping pong ball stay there on the last round?
i actually knew the answer cuz i tried both relighting and the slinky lol
I actually have some of those storm matches, they do keep going for a bit under the water but its not a burning fire like here. Plus they make a fuckton of bubbles from it. But yeah they don’t burn like that underwater.
I got the first one right, the second one I got wrong but it was an either or and I chose the wrong one and I noticed it being in reverse in the third one
I got them but I was really hoping I was wrong about the forks
I'm 99% certain its #3. Heat travels upwards so the fact the flame is traveling downwards makes little sense, seeing how there is almost no fuel for the flame, if any. The first is obviously real (I've used stormproof matches before, though typically they create a lot of black crap all over, so that's where my 1% lies.) and I don't want to go into detail #2, but I can confirm it.
There are storm matches that can burn underwater, so the only thing that tells us that is a lie is the way the flame looks and the specific brand of match. Underwater burning is usually exothermic electron transfer of metals, such as between aluminum metal and iron oxide
Nice
(round 2)
I am struggling to discern between 1 and 3. I recall a demonstration of 1 but cannot intuit a mechanism. For the water to be reflected by the comb, it should have a static charge, but i cannot intuit why it would. Meanwhile, a raw egg contains liquid, which may remain spinning for a short time after stopping the shell. After releasing the shell, the liquid could drag against the inside of the shell and transfer momentum to it.
I will go with my memory and say 3
Hahahahahahahhaahaahahahahahahahhahahahahaahahahshahahahahaha silly goose it was 2!!!! You couldn’t of got it more wrong!!! MWUHHAHAAHHAHAHHA
(round 1) 1. Underwater combustion is possible but the reason provided is bogus (grease combustion is not possible underwater and combustion conditions are not why water should not be used on grease fires (the water flash-boils, which physically pushes the flaming oil [ physically spreading the fire] and divides the oil into droplets, increasing the rate of combustion [combustion occurs around the surface of the oil, and dividing a substance into small pieces increases the surface area]).
The footage of the underwater match also looks unphysical. The match doesn't react at all to being submerged
2 and 3 are also results I was already familiar with.
I missed some details of 2 -- i thought it was just showing the ping pong ball being held up at all, which is a known valid result
And the fork one and battery one was fkaed!!
I have absolutely seen the very last "fake" one performed before
Got them all right
in the 2 round its actually not the comb that holds the static electricity but the oils from your hair that get on the comb
How does the ping pong ball stick to the bottle? Is there less pressure inside the bottle? Is it surface tension?
ikr the fork one makes more sense
I guessed wrong on the first one (I know combustion underwater is possible, and I've *done* the slinky thing, while the candle one seemed implausible) but got the other two correct. Though i am still dubious on the ping pong ball being as simple as it looked...
Me actually knowing the candle light trick actually works
The ping pong ball hairdyer thing was obviously fkaer!
wow that was way easier than i thought
Well you could have a fire underwater, but it should be like Phosphorus or a rough oil pipe that has also some air shoting out.
the ball on the hair dryer, wouldnt it just fly on a side? i doubt a hair dryer has such precise air flow.
the match one is possible tho , there are matches that can still burn under water
We tryed egg experiment on the floor and it worked
I've a match that can be used under water... which is why I thought it was true. I didn't know how they worked though.
there are water proof matches but instead of staying lit underwater they will go out but as soon as you take it out of water it will start up again
I knew the re-lit candle one was true (thanks science class!)
I got the first round wrong but round 2 and 3 were a success
Got all right
For the egg experiment do we need a brownish egg or a white egg
There is an element or formula that lets fire burn underwater! Still interesting tho
Clearly the first one
Its funny to think that thermite burns underwater. So i legit thought that the first one was thermite.
The match one fooled me only because ive seen firework fuses work underwater
Wait, how did you get the ping pong ball to stick to the lip of the bottle when you turned it upside down?
It's the same idea as how water gets stuck in a straw if you block off the other end of a straw. When you turn it upside down, gravity (very slightly) pulls the ball downward, but then because the bottle is sealed airtight it creates a vacuum in the bottle which loosely speaking sucks the ball back in. If you poked even a tiny hole in the other end of the bottle then the ball would immediately fall out.
For the first one - underwater matches do exist!
Got them all right haha!😂🎉
For me all!
i got them all right 💪
No explanation about the pingpong cap lmao
the other end of the battery was not connected
i got all right
Well i got the first 2 right, i have like a 2/3 score in these
I thought the golf ball floating on the hairdryer is due to the coanda effect not Bernoulli's principle.
2 out of 3! I am adequately intelligent/perceptive!
Definable the first one. This is my guess
Yes
