[@c82153]

From a fluid dynamics perspective: It seems to me that hitting the top of the bottle sends a shockwave through the water. Shockwaves have extremely low pressure at the front of the shock and extremely high pressure at the back of the shock. When the front of the wave reaches the bottom of the bottle, that low pressure zone generated by the shockwave induces cavitation (the little pocket of vapor you see at the bottom of the bottle). The water cant hold onto the air bubbles that are already dissolved in it or stay in its liquid phase in this low pressure zone, similar to why boiling water is much easier at the top of a mountain; the atmospheric pressure is less. When the energy of the shockwave dissipates, this vapor bubble (cavitation) collapses...very, very, violently. Often times at supersonic speeds. The force of that vapor bubble collapsing at supersonic speeds (which brings the water crashing down onto the bottom of the bottle), is what breaks the bottle, in my opinion. Perhaps Schlieren imaging could confirm this. It would follow that the CO2 bubbles in carbonation interrupt this shock wave from passing through the liquid, and keep the wave from reaching the bottom with enough energy to induce cavitation. The low pressure zone generated by the shockwave would cause the CO2 bubbles to escape from the liquid, causing the foaming in the beer you see This phenomenon is very similar to the cavitation seen in boat propellers. The propeller spins through the water, generating a low pressure zone behind the blades of the propeller, and when this pressure is low enough, the water can no longer stay in it's liquid phase, releasing any dissolved gas and changing phase to water vapor, generating the vapor bubble you see behind the propeller. When the energy from the propeller dissipates, these vapor bubbles collapse at supersonic speeds, changing the phase back to liquid and dissolving any air/gases back into the water, but at the same time gouging a chunk of metal out of the propeller. Edit: I've edited this post to clarify a few things, thanks to those who commented below!

[@mrosskne]

missed the part in the video where they showed the impact from the water shattering the bottle?

[@c82153]

@@mrosskne I watched the full video. My thought is that the source of that impact is not from the water trying to catch up to the bottle, but from the collapse of the vapor cavity induced by the low pressure region near the shockwave.

[@mrosskne]

@@c82153 alright, congrats on being blind i guess

[@c82153]

@@mrosskne this may surprise you, but physically seeing a phenomenon doesn't always reveal the correct explanation.

[@Celcius1]

@@c82153 actually its steam not air, your lowering the atmospheric pressure, causing the water to boil, so its not air its actually steam, same with cavitation on boat propeller, its not bubbles of air but steam, the water is actually boiling there is no air being released, if air was present in the water it would stop the cavitation from breaking the glass, that is why it has to be a water with no dissolved gases in it, when you lower the pressure of water, it boils giving off steam, not air, and the cavitation is the source of the glass breakage

Yep. It's the Water-Hammer effect. The water and bottle are pulled together by the vacuum created from the initial strike.

The first I heard of this was in college, with Sobe bottles. My coworker bought a Sobe bottle so we could try it out. The story we heard was that you had to keep it sealed for it to work. Hitting it gently, we could hear a loud cracking sound as the vacuum collapsed. Hitting it harder it broke easily. We tried with an opened bottle that was refilled. Cap on or off, it took a harder hit to get the cracking sound. My hand hurt too much to get it to break with the refilled bottle. I would love to see a test rig built to see the impact required for a sealed bottle vs an open bottle vs a refilled bottle with the cap on

[@Renuclous]

Maybe im missing something, but im irritated by "high vapor pressure works better". The low pressure zone at the bottom is formed solely because of the liquids inertia, so shouldnt either a) the vapor pressure of the liquid have basically no impact at all or more likely b) a liquid with a high vapor pressure start to fill the low pressure zone with evaporated gas and cushion the liquid-hammer? (basically what you said 5 seconds earlier about the Carbonation?)

[@MittyLittle]

On the foaming of beer, I did a research project in chemistry at uni with my professor. And we found that not only do you find that bubbles are made, and then increased because of a chain reaction, but this happens more so in beer than any other drink! And that's because that beer is just crazy good at foaming because the bubbles are more stable, mostly due to the fact that the pH is higher in beer than cider, soft drink, and other carbonated drinks. The more you know!
