I use a foot-long piece of 2X4, so the bottle remains totally unsealed. That's for all the people who insist that it won't work unless filled all the way to the top, so your hand will compress the water.

[@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

[@17713bb]

Yep. It's the Water-Hammer effect. The water and bottle are pulled together by the vacuum created from the initial strike. The water and bottle come together rapidly, and since water is in not compressible and has high mass, it's like hitting the glass with dense solid object and the glass shatters.

Two things this video impress me is that 1. They came up really easy way to test their theory. 2. The slow-mo technology makes it so easy to prove the second theory. That's such a amazing combination of big brains and technology.

There's another theory - a shock wave moves equally and radially down the glass bottle and crashes into itself when it converges at the bottom of the bottle directly opposite of where it was struck. You can see this effect in a video where a guy shoots a glass globe with a gun. The bullet penetrates one side but does not break the globe and on the exact opposite side the glass breaks as if it were shot on that side as well. This is from the convergence of the shock waves on the opposite side.

Point 3 is wrong, if you have a higher vapour pressure liquid, it will fill more easily the bottom with gas (similar to what happens with the beer). You actually need the opposite, so there is nothing in between the liquid and the bottom when they meet again, this will maximize the impact velocity.

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!

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

3:30 Without seeing the rest of the video I'd assume it's "water hammer" a.k.a. the volume of rapidly moving water hitting the bottom. And that movement is obviously caused by the vacuum. Similar mechanism is used during water forming to create curved surfaces out of metal for some cars.

[@johnlarson4194]

Sound waves that are so strong will travel through the tube of the bottle and the pressure of the sounds are so fast and hard it cause the bottom to destroy the bottle the reason it breaks at the bottom is because that's how the sound waves realize their out of a small narrow area so they know they can release.

Air don't need to be entered at the top cause hitting the top with force builds the pressure in cause a bottle isn't air tight anyways with a lid on. The bottle has some air init before opened, but the rubber hammer or the Parm of your hand must play a part init to stop the air escaping out the top once hit so the only way is down My theory would be try hitting the hammer on the top without creating a seal, only hit the rim or the edge with all the same procedures as you did Or try diffrent bottles or wider bottle necks with also my theory 🙂

BRUH THATS A BOTTLE OF CORONA BEER

[@zwr1480]

We tried this years ago and quickly got bored with busting beer bottles. I had an empty Boone's Farm wine bottle and we all gave it many tries. All of us had bruised hands for a week, but my brother finally knocked the bottom out of it lmao it was spectacular

I've been drinking beer along time. Why did it take 5yrs for this to pop on my feed!
