3 Perplexing Physics Problems

Opened the comment section for it

Nicely spotted

I thought it was a spider!

It also went through a falling ring!

ikr. like what were they doing

@@TheGameChallenger no a simple pressure gauge is and was available pretty much everywhere Even if a simple device that checks increase/pressure would work (example simple piping can be used to make a working pressure measurement using Bernoulli's principle(

@@glkglkglkglk9193 ah I see. That would definitely define a cause but the phenomenon still shouldn't occur under this premise. This may require further testing.

This is most likely due to a phenomenon known as "disloyalty", in which fathers and other close family members have been known to spontaneously disappear, never to return

Aw, sorry to hear that. Something similar hppened to me too.

Actually, the sound is made up. Sound at such slow motion videos doesn't make sense, and so it's manufactured and edited in the video afterwards just to make the thing feel better.

@Daniel Kintigh Not about beating anybody :) just about letting people know. Since rapid cameras record high frame rates only to lower them at editing, they're effectively slowing time. Sound are air vibrations, and pitch is a sense of the frequency of those vibrations. By "slowing time" 10 times, all sounds reduce their frequency by a factor of 10, and so many audible noises would become infrasounds, and other high pitch sounds would become very low. Weird stuff, but it's cool to see how people came up with the idea of editing audio and make it sound Slo-Mo like

I never thought about this and now I want to calculate it. But there are so many variables when it comes to tire base strength due to the compounds used and I'm not a tire expert :( very interesting though.

There is only one way to find out

and what about the gyroscope effect, is it significant?

You'll have to define 'support'. So-called run-flat tires rely on very strong sidewalls to temporarily acheive this. How could you measure the contribution of sidewall strength vs centripetal force vs any other variables I'm not thinking about?

@@mrjbexample That speed is surprisingly low. However, it is virtually impossible to achieve with 4 flat tires in a regular car.

It only works with certain carbonated drinks, my chem teacher said something about it not working with diet sodas or something

John Dorian 3-tap method

@@dougswainson4704 I drink a lot of carbonated drinks, I know it's not healthy, but I've never met one it didn't work with. I've actually gotten into a habit of shaking them up and tapping them before opening. Regular, diet, zero sugar, Sparkling water.... Works with everything I've tried

agree

Hold my non-equalibrium beverage

5:21 fly on his middle finger

🤣 amazing.

omg I was so off put that I had to see the comments form someone that noticed that

Yes and no. The tapping doesn't do very much if anything, it's the waiting that does it.

NK_20 but he just showed that it does and why in the vid...

NK_20 no, waiting just means you are waiting for the bubbles to come off of the walls of the bottle, but tapping them gets rid of them from the walls, meaning it won’t fizz up as much

Steven Spencer sameeeeeeee when he was taking abt the air bubbles I automatically thought to my self y do my friends do that to a come bottle 🤣😂😂

Tapping on top doesn't do anything. Tap it on the sides instead.

Kinda sounds like a civilization being established (idk of that makes sense)

Funny thing, that's not the real sound, the sound you heard are Foley sounds.

Nice profile pic : )

Honestly, if you satisfying just with it, You have a good life

The sound is fake btw they add them in editing to make the video look and sound better. Don't believe me search it up.

Normie: Shaking the bottle makes it foam. Me: Rapid acceleration and deceleration of the polymer container holding non-equilibrium beverage introduces an increased amount of nucleation sites, thus accelerating the dehydration of the aqueous carbonic acid.

Who else re-watched this at timestamp several times in awe of the fly?

@@vee_889 same 😂

Possibly less nucleation sites than a paper one too! Idk for sure though. Was the taste better than some of the paper ones?

revenevan11 I’m sure any straw would taste better than a paper straw

But also sounds like it would add a slight taste.

Veritasium says nucleation sites, but I also say air bubbles. Many tiny air bubbles simply vastly increase the surface area, through which the gas can diffuse out of the liquid. The use of the term nucleation is inappropriate - except in the case of the mentos.

It's a scientific word of bubbles!

@@yourevolution7850 As a kid, I loved playing with many nucleation sites made out of a homogeneous mixture of sodium hydroxide and dihydrogen monoxide.

@@Azakadune Bravo sir.

It's more of a chemistry thing then a physics one. Chemical equilibrium is probably something he could do an entire video on. Basically when you first seal a bottle of soda there's some CO2 dissolved in the liquid soda but not a lot in the air above the soda. CO2 wants to be a gas at room temperature though so some CO2 molecules separate from the soda and go into the air above the soda which increases the pressure in the bottle until the air above the soda can't take anymore CO2 which means theres a maximum pressure that can exist in the bottle from CO2 ( this process takes a long time under normal conditions though). When the pressure is at its max we say the CO2 is at equilibrium because the pressure stops changing. It turns out that there's a ratio for this process so there will always be x molecules of CO2 in the air for y molecules of CO2 dissolved in liquid and that ratio doesn't change unless you change the temperature of the bottle which shaking doesn't do. The reason soda sprays out of the bottle when you shake it is because the CO2 that would have escaped anyway in an unshaken bottle is mixed into the soda more (in the fizz) so the CO2 molecules hold the soda and take it out of the bottle with them. The other reason is that when you open the bottle the pressure drops so ratio of CO2 in air vs liquid is no longer in equilibrium and the CO2 will want to go into the air to try to reestablish the previous equilibrium. This happens slowly in an unshaken bottle (or cup) but super quickly in a shaken one because the air bubbles along the sides of the bottle help the CO2 separate from the liquid much faster. I hope this makes more sense

@Seymour Kuntz ya but with equilibrium

And the yoda questions were the biggest “understand didn’t I accepted it but” things

It was kind of a trick question. If you open a bottle and release the gas, then immediately cap it with his pressure gauge, it'll says "low". If you then shakes the bottle, the pressure will immediately jumps to "high", just like a lot of people expects. The trick he did in the video, is that he didn't immediately shakes the bottle, but instead let it rest so then the CO2 slowly releases from the coke. That way the pressure gauge will already starts at "high" before he shakes the bottle, creating an illusion that pressure doesn't change even after shaking.

@@nggdowt Not really a trick, a freshly bought soda bottle from the store (which you can reasonably expect to be at equillibrium) will still explode ergo the reason for exploding soda after shaking is not a sudden increase in pressure.

Oh yeah and "Smarter Every Day"!! How could I forget Destin?!
