Yeah, I don't think the pressure drops due to water condensing, there isn't enough vapour in the air to make a difference in pressure. The pressure decreases because the air pressure of the actual air just decreases with temperature. Its like opposite of the old trick where you heat up a dented ping-pong ball to fix it since the air pressure increases inside it when heat is added.

This is the first video, where I predicted the reason before Steve said it!!

The pressure the explosion can produce is limited by vapor pressure of the superheated water, which is a function of temperature. And it would take some serious overheating. But i am meaning to try that, I hope for best destruction if I cover up the surface with a layer of oil, to prevent heat loss to evaporation from surface, and potential disturbances there. I know how much of a mess the water can make in a frying pan, submerged under oil.

If somebody knows at lower pressure water boils at lower temperature, it is not that difficult

I came up with a similar explanation. As temperature and pressure are directly proportional, the decrease of air temp decreases air pressure on its own as well as recondensing the vapor.

No need to apologise for passing on information, but nice that you credit your source. I understood the phenomenon already, but hadn't seen it demonstrated without lab vacuum pumps. Nice!

You can use thermal shock on a bottle to make a clean straight lip. Tie a piece of string around bottle and soke with meths, set fire to it and when string falls off it cracks where the string was tied. Not done it myself but was on a video years ago.

This video nicely illustrates the fact that heat is nothing else but the vibration of molecules. The higher the molecules move, the greater the pressure (due to repulsion between electrons). Cooling down the vapors, means slowing down the atomic movements, which lowers the pressure, allowing new bubbles to form, eventually reaching an equilibrium. Very nice experiment!

In 10 years, another KZreadr be like: I think that video deserves a remake, as that old video is only 4K@60fps so basically ancient.

You could also think about this in terms of reaction rates. Since the product of boiling (water vapor) is also the reactant /input to the process of condensation, if you increase the rate of condensation, you shift the equilibrium of evaporation towards the product side, so that evaporation occurs more rapidly.

A related and even more impressive experiment is the crushed barrel one. You boil water in a steel barrel and put the cap on. Proceed to cool it down with cold water. As the steam condenses, a vacuum is formed and the ambient pressure causes the barrel to crumble.

I'm happy that I was able to figure out how it worked before I clicked on the video!

had in itch about how it worked as soon as you said to quickly close the bottle not something I'd think about but it makes a lot of sense The super heating is super interesting as well! I've know about the super cooling and the difference in energy to get water from liquid to solid but not about super heating ^^

The superheating of the water is also the reason why there was at least one larger stone put into the boiler of steam engines, like on locomotives, after they had quite the number of accidents from water suddenly starting to boil and tearing apart the boiler in the process.

I experienced the super heating by accident when I was just trying to heat up a small amount of water in my microwave in a glass cup. I took my attention away from it for a few seconds and I heard an almighty whoosh and bang and thought I'd broken my microwave. When I opened the door the water was gone from the glass and the inside of the microwave was covered in water. It gave me an excuse to wipe the inside clean but at the same time I realised this wasn't a good idea in the future as something terrible could have happened. Thank you for helping me understand what happened :)

I'm glad to say I figured out the answer before he explained. Not immediately, but still.
