3 Perplexing Physics Problems

Why does shaken soda explode? Does ice melt first in fresh or salt water?

This video features experiments that have been shown to me by science teachers over the years. Does ice melt fast in salt water or fresh water was an experiment introduced to me at the Utah Science Teachers' conference. The ring of metal over a chain demo came from a teachers event in Florida. The idea shaking a carbonated drink increases pressure came from an email.
Special thanks to Petr Lebedev for building the pressure gauge.

The problem is it has taken my father 18 years to make this trip and I want to know how this strange phenomenon has occurred.

I was at a place where people were selling all kinds of puzzles and things and one that they were demonstrating was the ring and chain. The guy said he would give it to me for free if I could get it to stick on my first try. So instead of just going for it, I looked it over and thought for a second and pictured in my head what I needed to do to get it to stay. So I dropped it correctly and it stuck and the look of shock on the guys face was better than a free puzzle.

[@marekklemes4192]

Similar to the ring latching on the chain, an inverse kind of trick is to pull off any elastic from a large number of them looped around the same stick. Pull on your chosen one away from the stick, then pull the loop over the top of the stick and you will liberate only your chosen elastic while leaving the others on the stick, (instead of having to pull off all the ones above it or something equally messy).

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?

very interesting video but i have to say one thing about the carbonated drink normally (at least in austria) if you buy a bottle with a carbonated drink in it and you shake it, the bottle will be harder to compress, which means that the pressure increases however we all know that it doesnt get harder to compress anymore after a sometime of shaking or just standing somewhere so if you ask if the pressure will increase, the answer to this question can be different, based on some variables

[@edouarddubois9402]

The slowmo sound of the ring and chain was very satisfying.

[@rojirrim7298]

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.

[@rojirrim7298]

@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

No. 3 is depending on length and weight of the chain, distance between the chain strands and also on weight and rotation speed of the ring. The more you increase the length of the chain, increase the weight of the chain, reduce the distance between the chain strands, reduce the weight of the ring or decrease the rotation speed of the ring the more unlikely it becomes to achieve the same result. It's like the phenomenon of a buttered toast falling from the table mostly landing on the buttered side.

Me: "Air bubbles" Veritasium: "You mean nucleation sites."

[@spamcrud5639]

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.

[@knotten33]

Try thinking of it in it's reverse. If you take the chain (which is a enclosed loop) and thread it through the ring so you have two equal lenghts of chain with the ring hanging in the middle, you then take one of the sides of the chain and loop it through the other side of your chain. As long as you pull on the side that you looped through your chain, the knot will stay tightened. 4:15 is the same thing but with the ring going through the chain and it's just a bit flashier because instead of you doing the loop by hand, gravity, inertia and the geometry of the ring is doing all the work for you.

When I was a kid, I discovered that you could stand up a straw in a glass of soda pop and miraculously, soda would come out of the top of the straw slowly like a tiny fountain. Back in those says, the straws were all paper. You have shown me the answer to this phenomena and I thank you.

[@maxmustermann9587]

Not entirely. When you put a straw into any liquid the liquid is pulled upwards into the straw. That is called capillareffect, a combination of adhesion and cohesion counteracting ambient air pressure. The smaller the straw the higher the liquid will be pulled. That effect is used by trees and other plants to bring water from the root up to the top which can go up to 650ft (200m). The 'fountain' is the result of in the soda dissolved carbon dioxide being released within the straw because of the rough surface of the paper straw.

[@koitorob]

@@maxmustermann9587 No it's not. Stop making up your own words Einstein. It's called capillary action or capillary effect or even wicking.
