Does a comb attract faucet water? (2 Truths & Trash)

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?

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

[@Metal_Master_YT]

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)

And they would bubble

[@helper_bot]

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?)

[@U20E0]

@@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

[@paulmartin2348]

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.

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.

[@toycatsowl4388]

Or is it just because you are a Porygon-Z?

[@Owen_loves_Butters]

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.

[@namelesscage]

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.

[@Owen_loves_Butters]

@@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.

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

[@johndolenc7658]

#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.

No waterproof matches work while wet but the fire still needs oxygen to burn

[@Graf_Yuki]

i actually knew the answer cuz i tried both relighting and the slinky lol

[@sssilky3317]

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)

[@krikukiks]

The first one is correct only on technicality. Because you say it does "nothing" to the burning. But it does keep burning under water

[@Blubbpaule]

in this video it was pretty easy to see edited footage / backwards footage.

[@lordrefrigeratorintercoole288]

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.

[@DirtBikeBoy5ive]

Dude the first one all three *CAN* work. They make matched with oxidizers that burn underwater.

[@linkofdoom24]

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.

[@gavin5410]

How does the ping pong ball stick to the bottle? Is there less pressure inside the bottle? Is it surface tension?

[@jsosianimations]

ikr the fork one makes more sense

[@janski1476]

wow that was way easier than i thought

[@keiyakins]

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...

[@ivorypartnaite8619]

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?

[@claaws6851]

Its funny to think that thermite burns underwater. So i legit thought that the first one was thermite.

[@r..7689]

[@jessegauthier6985]

1 out of 3 lol I assumed the first one was a trick question

[@klikkolee]

(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

[@pickle_eater_290]

I got the first round wrong but round 2 and 3 were a success

[@EdKolis]

Wait, how did you get the ping pong ball to stick to the lip of the bottle when you turned it upside down?

[@asdfqwerty14587]

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.

[@dartimes6048]

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'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.

[@_charademon_]

For the first one - underwater matches do exist!

[@johndolenc7658]

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.

[@ZonaLol0000]

[@justaguy4311]

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
