Bare-handed bottle smash

Description: SAFETY WARNING: If you wear a ring, you might shatter the bottle neck and slice your hand. It's quite easy to blow the bottom out of glass bottles ...if you know the secret. Even wine bottles sometimes work. But not cider jugs, since the pressure peak is small if the square inches is large.

(some particles in it)....would this work without a liquid substance? simply by sudden exertion of air from the top? __________________________________________________
Mikal503 ::: Favorites  2007-08-23 14:33:44 thats awesome, thanks :P but it kinda sucks it doesnt work with beer; itd be awesome to grab someones beer and blast the bottom off the bottle, haha :P __________________________________________________

wbeaty ::: Favorites  2007-08-23 15:17:12 > what was in the last bottle? (some particles in it) I've heard it said that this trick only works with distilled water. To prove them wrong, I added coffee creamer and tea leaves. In truth, it only works if there are few or no nucleation sites present. But for boiling, effervescence, and cavitation, the nucleation sites are microbubbles, and NOT floating particles. __________________________________________________

It works much better than slamming a bottle sharply on a tabletop. But it's difficult to hit it hard enough. To make an instant beer fountain every time, grab somebody's beer, then whack the top with a short piece of two-by-four! :) __________________________________________________

Calliber50 ::: Favorites  2007-08-23 23:07:12 Man I spent one drunken night with my friends trying to figure this out. Needless to say all of us had bruises on our palms. Being engineers we then made a device with a 2X4, a rubber glove, and some foam. I thought you need to get a perfect seal with the bottle top and your hand. I guess not! __________________________________________________

Jei42 ::: Favorites  2007-08-24 02:26:53 Break that one out just about every time I'm drinkin' around new people.... Always thought it was a hydraulic pressure thing, pressure of the air forced into the empty bottle neck.... Appreciate the enlightenment. __________________________________________________
Russoft ::: Favorites  2007-08-24 18:19:19 I'll have to try that. Too bad it doesn't work with beer, because I was just looking forward to pissing my friends off by breaking their bottles, haha! __________________________________________________
wbeaty ::: Favorites  2007-08-24 19:04:29 > Too bad it doesn't work with beer. There's a similar trick with beer. It goes all "Mentos" on you. Just whack downwards on the top of their full beer bottle, using the bottom of your full or empty beer bottle. With yours, nothing, but with theirs, beer fountain! (Their bottle must be hand held, so it can move sharply downwards.) __________________________________________________
Russoft ::: Favorites  2007-08-24 19:19:33 Oooooh! That's why that trick never worked before! I thought it was vibrations in the glass that caused it to bubble. So it's from the vacuum that's created? I always hit them when they sat on a table and only got mediocre results (very mediocre). __________________________________________________
wbeaty ::: Favorites  2007-08-24 20:38:06 > So it's from the vacuum that's created? Yeah, it's a *negative* pressure pulse. Liquids can support negative pressures because of attractive bonds at ambient pressure. Create a large enough negative pressure, and no nucleation sites are needed. Instead, millions of bubbles appear spontaneously. (Heyyy.. perhaps ion trails from cosmic rays would be visible for a few mSec?!! In particle physics' bubble chambers they use liquid hydrogen.) __________________________________________________
