  • it's the sudden compression of air with a bit temperature imbalance.

    doesn't get my gusset creamy. why do you do this to me Tube :D

  • could u use this without water and just beer?

  • @imfromtambunan See "Time Warp" bottle smash episode. They try it with beer, and even a rubber mallet, but the CO2 in the cavitation cushions the hammer effect. But really that just means for beer, you need to hit it much harder. Water avoids bruised hands and wasted beer.

  • This is really cool!

  • That man, is amazing. o-o

  • Mind=blown

  • IT ONLY WRKS WITH NON CARBONIZED DRINKS THUMBS UP SO REDARDS DONT HURT THEMSELVES

  • 0:39 fail!

  • That is truly mind-boggling! Does it work with oils also? Cheers.

  • HULK SMASH

  • I finally got it last night with a blue moon. Thanks for helping me look impressive!!

  • I tried, the bottle didn't break, my hand almost did, though. I guess it trial and error, maybe....

  • @armydude96 Yeah, some bottles are way too thick.  Henry's Blonde ale breaks easy. Henry's Blue Boar has a thick bottle. You can break it eventually, but you'll get a bruise!

  • NOOOOO THE SWEET AMBER.....

  • @samn100 Beer won't work, so in order to perform this physics demonstration you must carefully drain the bottle, then re-fill it with water.

  • @wbeaty i know :0 just imagined that the bottles were filled with it

  • @samn100 Avoid thick bottles: once you find a brand which works well, carefully drain many of those. Then you'll be set.

  • @wbeaty ok thanks

  • 0:27 hahahahahahahahaha

  • I've learnt more in an hour watching these videos than I ever did at school :o), brilliant stuff!!

  • I tried it, It doesn't work :(

  • @guitargod909 Try hitting it with something besides your hand. I couldn't get it to work either but then I used a thick piece of wood instead and it worked. It's likely either because the bottle was very strong or I was too weak.

  • @Duckman1616 Don't forget to be paranoid about slicing open your hand. Don't forget to use "old" water or bottled water. Yep, some bottles are way thick and impossible to break. Once you find types that work, keep using those. Henry's Blond works, Henry's Blue Boar is too thick.

  • Just a note: Those pockets of "vaccuum" are actually empty. When you hit the jar, the force you apply to it causes the pressure in the fluid to decrease rapidly for an instant to a point below its vapour pressure. This causes the fluid to boil for an instant creating water vapour

  • @kyle3420 Actually it's even stranger. Water can support extreme *negative* pressure. When you whack the bottle, you don't just create vacuum, you instead go way past that. Water has bonding force (the source of surface tension,) and you won't get any internal boiling unless you apply a large force that opposes the liquid bond force. Make an enormous anti-pressure pulse, and any microbubble in the water will cause a "tear," and the water opens up around a vacuum pocket.

  • @wbeaty No its not a vacuum, I'm saying that cavitation is the formation and subsequent collapse of vapour bubbles. Surface tension doesn't really have anything to do with this phenomenon, it's the vapour pressure of the fluid that you have to consider.

  • @kyle3420 Yes & no. Vapor is irrelevant; this still works regardless of vapor pressure. (Try this w/vacuum pump oil or icewater.) Besides, liquids don't just boil, instead they superheat wo/bubbles. The actual pressure causing cavitation is *negative.* That's why nucleation sites are a major issue. Neg. pressures only arise with liquids, not gas, since liquid has internal bonds and must be forced apart before a fracture or bubble appears. Large internal fluid tension, not surface.

  • would it be easier with hot water? or real cold water? or just room temp?

  • @nikedunks7 Hot water probably makes cavitation pockets more easily. But as with beer, there will be gas-cushioning, so maybe it doesn't work as well.

    And cold water might be harder to cavitate at all. If this is right, then there must be a special temperature which works best!

    Or, just use really cold water, shake it up a bit to create microbubbles, then wait a few minutes so all but the tiniest bubble has been cleared out. That way you have seed bubbles, but much less outgas-cushioning.

  • what a waste

  • You are awesome, Mr. Beaty. You're such an inspiration for people who love being nerdy and knowledgeable

  • dont abuse the booze

  • Why? WHy? WHY??

  • HEYAH!!

    ...that doesn't work...

    ROFLLOLOLO

  • then... you drank tap water thats been sitting around?

  • Demo at 2:00 very educational.

  • LMAO AT 0:47

  • i dont get it first he says use beer bottles then he says doesnt. kinda confused can you help me out by understanding what kind of beverage and bottles you can use to break the bottom.

  • @armenianply don't use beer or soda. Fill beer bottles with water (bottled water works better than tap water.) Note that some bottles are easy to break, while other thicker ones are nearly impossible. Also, DANGEROUS DEMO, USE GLOVES AND SAFETY GOGGLES.

  • @armenianply most glass bottles work

  • you can cut a tendon on your finger doing this! I still got the scars

  • lol I literally couldn't stop laughing after 0:48 hahahaha it's proper funny :D

  • almost looked like cavitation taking place at the bottom of the jar.

  • > almost looked like

    Cavitation IS taking place at the bottom of the jar. Watch closely starting at 1:30 It's pretty obvious

    However, it doesn't have to be at the bottom. The farther up it cavitates, the less mass is in the moving cylinder of water.

  • Alcohol Abuse!!!

    You just don't do that with good Alcohol.

  • > Abuse!!!

    Doesn't work with beer: too much CO2 gas, it acts as a cushion. For best results, you must first use up the beer, then replace it with bottled water.

  • Hes just saying you wasted a beer lol.

  • @wbeaty Can you do it with a plastic bottle? or is it to tough?

    Great video's by the way! Keep up the good work!

  • LMAO that doesnt work you will just hurt your hand , i laughed at that so hard

  • Actually I have blown the bottom of a beer bottle with BEER in it on the first try, It was a Dos XX I believe. I thought it wasn't going to work but It amazed me and my friends. and it was actually pretty easy.

  • @f3rnand0p it works with beer if you use the edge of a 2x4 instead of your hand. You just have to hit it lots harder. Maybe I just had a thick sturdy bottle. Some bottles are definitely far stronger than others.

  • 0:48 lol

  • Why would you waste all that beer lol

  • Doesn't work with beer, must use stale tap water.

    With beer, it does create a foam fountain.

  • I successfully did this with a Budweiser bottle, worked on the second try. It was awesome! Gave myself a nice bone bruise from hammer fisting a wine bottle, failed. Must wear goggles.

  • yeah why the heck was this flagged i thought u finally messed up big time and cut yourself and filmed it lol

  • who the fuck flagged this?

  • > flagged this?

    @Kissrocks1000 perhaps it's FCC rule against drinking beer on camera? (watch whole vid. It's water. Beer doesn't work.)

    Prhaps smashing glass on floor with flying fragments is hazardous, and I didn't carefully give safety instructions? Didn't wear goggles? *NO* instructions can make this safe. Part of entertainment value is depiction of risky behavior requiring skill to avoid serious injury (then, I INCLUDE SCIENCE)

    YT silently sets vids to 'over-18' wo/explanation. Why?

  • @wbeaty You crack me up :DDD

  • An awesome, inexpensive demonstration of caviation's destructive effects. No need to show the boat propellers in introductory hydrodynamics labs--just pull out your bottle of out-gassed water and slam it hard!

  • can you combine this with watch?v=3qFXyEFMwBE - that would be awesome! (supercooling is a great effect anyways...)

  • pretty cool!

  • repeat click on 0:43

  • I lost a huge filling. So I made this video without having to blacken my teeth for a disguise. The missing tooth was real!

  • im gunna try that....with leather gloves so i dont cut off my hand

    0:47 hilarious

  • 0:47 lol

  • yea pretty funny

  • rofl that was funny

  • i found it easiest to hold the bottle around the neck, and THEN hit it

  • HAHA.. this guy is amazing... that cider jug part was hilarious

  • finally got this to work! see the video response

  • i tried this a few times...i got it to work actually so i know this is real

  • I submitted this to mythbusters, i believe that this would work, but I want to see Adam and Jamie try it, or build a robot to do it for them. lol

  • why is this flagged?

  • alcohol?

  • aahh ok thanks

  • But there is no alcohol in the video. And even if it was it is absurd...

  • probably this: "DANGEROUS DEMONSTRATION! If you wear a ring, you might shatter the bottle and slice your hand. And sometimes the whole bottle breaks into razor-edged shrapnel."

  • Ah, ok. Guess it makes sense. Sort of. No, wait, it doesnt... ;)

  • i really want to try this!!

  • yeah srsly, this shouldnt be flagged

  • who flagged this? whoever did is a moron

  • All that booze.....gone

  • Don't be silly. IT ONLY WORKS IF IT'S WATER.

    Remember? "water ...that's been sitting around."

    But with carbonated liquids, if you whack someone's beer bottle on the top, the cavitation causes a froth explosion as if you'd stuffed mentos in there.

  • Holy crap lol, not for the kiddies but an awesome thing to try nonetheless!

  • Billy B is a legend!

  • man does it hurt?

  • i broke a bottle in my hands once but i crushed it...idk how i had half a bottle of everclear before that and i crushd a beer bottle just with my hands but i cut the fuck outta myself but i still wish i knew how i did it....i blacked out soon after

  • Worlds. Greatest. Video. :D

  • that was pretty cool and kinda funny

  • Why is this video flagged?

  • LOL nvm i see the comment below. D:

  • False flaggers or idiots did it. Alcohol use is well within Youtube's TOS.

  • Probably afraid of the safety warning about broken glass.

    I've split lots of bottles, but none ever shattered. To be safe, just hold them high up on the neck.

  • Probably. xP Oh well it's a cool trick! :D Thanks for sharing!

  • The first bottle, is that Santa Cruz Organic? I just got done drinking that.

  • Yup. Pina-colada. (But it's full of water, with a little coffee creamer, and a good vacuum.  See the text caption for how to make one..)

  • i think you got flagged cuz...your video had alcool usage XD

    great vids! i actuly learn stuff :D

  • No, it doesn't work if you use beer. You have to use water.

  • thats stupid because its not even achool or beer

    its just water

    so waters from a bottle has been to dagerous for children now?

  • > How did this get flagged?

    Probably "behaviour likely to cause serious injury."

    Apparently the entire bottle shatters sometimes, but I've never had it happen to me.

    If you hold the bottle wrong, and if it does shatter, you could slice your hand open.

  • YAAAAAAAAAAAAAAAAAAAAAAAAAAAAA

    That dosent work that will just hurt your hand. lol

  • AHAHAHAHAHAHAHAHAHA...i loved ur scream at :47...SO DAM FUNNY :P...good vid also :D

  • i tried this about 20 times and only got it to work once. the end result was a very bruised hand

  • >i tried this about 20 times

    Some bottles are VERY sturdy.  Try other beers? Henry's Blonde Ale worked well.

    Also, the martial arts (and golfers') trick is to hit THROUGH the bottle, as if it wasn't there.

    That way you hit it very hard, and it breaks. If you hit it softer, you get hurt, because you have to perform many re-tries instead of just one success.

  • this is awesome

  • hahaha that was fun! :P

  • 0:47 lmao this man jokes lol

  • haha your awesome

  • LOL!!!!!!!1 keep clicking on 0:48 hahhahaa its so funny!!!!

  • lmao! WAH! WAH! WAH! WAH! haha

    ah that's great

  • so great!!!!

  • indeed lol

  • :48 OMG LOL i was laughing so hard

  • i saw this on time warp, it was cool.

  • i think i saw you on the history channel talking about static electricity in the dust bowl today!

  • i tried, didnt work

  • Wow, thats really interesting :O never saw vacuum "bubbles'

  • red stripe? really? lol...letting it touch another bottle slightly by accident causes a chain reaction, they are soo fragile. but good show

  • Haiyaaa! xD

  • WHHHHHHHHHHHOOOOOOOAAAAAAAA!!! Great videos! I love your holograms. I tried the V thing that you had on your website, but it came out really distorted. I'm glad that you tell others what you know.

  • Intresting, thx!

  • OMG, me and 3 of my friends tried this today..

    We tried SOOOO hard but we didn't get it to work :/

    We tried adding more water, pouring out water but it just didn't work :(

  • Fill it to about 1-1/2 inches from the top? If you followed these instructions, then it was probably a too-thick bottle.

    Some bottles only work when you hit them hard enough to guarantee a bruise on your hand. So try LOTS of different company beer bottles. (Those Red Strip ones seemed fairly easy.) Or start out by cheating: whack them with the edge of a short 2x4 board. You'll discover the weak ones.

    It's best to use bottled water. That way the microbubbles are gone.

  • Oh, our bottle was pretty thick i think, but that's the problem here in Sweden, all beverages that come in glass bottles uses the same sort of bottle, just because the companies reuse the bottles.

    It's only imported bottles which looks different, better look for something imported :)

  • your funny: "Heeya (cut off) That doesn't work." nice video, even though I'm only 11, i find these videos to be both educational and entertaining!

  • You make great educational videos. =)

  • you seem like a cool college teacher also im only 13 and i believe i am more mature than these jackasses who in their right mind would smash a bottle, WITH INTENT TO STAB them i mean what the fuck illegal not only but dangerouse and life theatening.

  • It'll be all right for back street brawls :)

  • "3 dollars a bottle!" xDxDxD He's a genious!! :D

  • the more i see the more i love this guy.

    he's a shining example of what we can do with an education. :)

    0:47 has me lol every time.

  • Charles Shaw!

    Hah, no big loss there. My friend tried this one time and the bottle shattered all over the place. Luckily he was wearing gloves because he was worried that exact thing would happen.

  • i saw that on warp zone. Pretty cool.

  • You mean Time Warp?

  • LOL "that--- does not work...", and good for bar fights, you have half full beer someone attacks you you smack your bottle of wine/anything else, and stab them=].

  • Nice, except for the fact that he specifically said it doesn't work with any sources with "micro-bubbles" or carbonated substances. However wine would probably work.

  • That impact at 0:39 had to hurt...

  • not as much as you think,

    you have to condition your hand

    so it doesnt hurt

  • @ IRAiiNx: or you could just deal with the pain *glances down at the cuts and bruises on my own hands* ... it's just a sign I've been doing something awesome, like this ;)

  • Hahaha i laughed alot at 45 seconds!

    Nice videos, very interesting! Many thanks!

  • do you have to do all these steps or could you just fill a bottle with cold water and do the same thing?

  • Raged..

  • awesome videos!! iv subbed for a while and cant seem to see my sub box get filled with your videos. Make some vids when you get a chance, its awesome to learn somthing new!

  • NICE :DDD

  • i broke a beer bottle with beer in it. it has to be just right

  • cool! i`ve tried this trick, but never got it to work, water does something to the structure of the glass, i found out by accident washing the dishes, when for example a regular drinking glass is submerged in water you can cut it with scissors quite easily. try it!

  • i hope that was water in those

  • he said at end that it has to be tap water duh!

  • Sometimes beer will work if you use the weak type of bottle and hit it hard with something solid (like a second beer bottle.)

    To guarantee success, figure out which brand of beer has the weakest bottle. Then use water instead of beer. Then first let it sit for awhile to clear out the microbubbles. That way it works every time ...and even works with much larger bottles.

  • Of course its a water -.-

  • Seems like something you might see on Red-Green lol.

  • wbeaty have very good tips and science project love them all thx for the bottle tip i will shwo to my friends XD 5/5

  • very cool man

  • Probably not a great idea to do this in your driveway where you could run over the glass. :)

  • Ha! After years, you're the first to notice that.

    I started out with a wastebasket below. But then I found that it was simple to clean up the few splinters of colored glass in the wet blotch. The gravel tends to grab them so they don't bounce at all. My footage without the wastebasket looked better, so I used that.

  • Thanks for having a sense of humor wbeaty. You rock.

  • I like your Guides and videos I try to do that 5 times and in 6th it was succesfull Thanks =)

  • tap water is so clean.

  • at 1:57 what is all of the brown stuff in the bottle???????????

  • Tea leaves. I wanted to see if solid impurities would have any effect on the cavitation pockets. They didn't.

  • omg this is funny

  • LMFAO!! 0:49 the best thing ever...especially the audio lol

  • hahaha 0.49 was sooo funnnn!!

  • LoL this video made my day.

    This guy is AWESOME!

  • lol 0:45 to 0:49

  • has to be non-carbonated

  • we know..thats what he told us...

  • Guys you gotta hit the top of the bottle.

  • if you wrap the top of your hand around the lip of the bottle, its ALOT easier to explode the bottom out (view my profile if u wanna see, i have a video)

  • > its ALOT easier to explode

    It's way easy to shatter the bottom if you hit the top of the bottle with the edge of a short piece of wood (like a 1x4,) No pain. Works every time. And you can strike the bottle quite gently.

    Try watching the water in bright light against a dark background. When the wood hits the top, you'll probably see the cavitation bubbles.

  • omfg u made me laugh like hell when y try to break the large bottle

  • :)

    Hilarious these guys trying to argue here. What they say on TimeWarp:

    'The break is actually happening because the water is separated from the bottom and drawn back to it at a really really high velocity'. Go ahead and check it out, in the link wbeaty posted below (the actual sentence at 2.18-2.25). The explanation they have is just as given here by wbeaty.

    Thanks for a nice demonstration.

  • What fascinates me is that perhaps someone besides myself penetrated this misconception. I REALLY want to hear the story behind their discovery.

    The false belief is universal and hotly defended; that the bottle is shatted by "air pressure pulses" from hand-strikes. Nobody discovers the silver flash of cavitation. It takes abnormal tactics to disregard apparently solid knowledge and instead just watch and listen.

    But more probably they just lifted the correct explanation from my video.

  • Its air pressure that cracks the bottle open. They explained it on the discovery channel. Thats why it doesn't work on full bottles. Nice work idiots. When trying to figure out something complicated its usually the simplest answer

  • > hey explained it on the discovery channel.

    Yes, their explanation is correct: cavitation, and it's the same as mine, go watch their vid: youtube com/watch?v=cOeNxkksruo They say "Warped at 10000 frames/sec we can actually se the vacuum form on the bottom" and "The liquid rushing to fill the bottom, and just blasts out the bottom"

    Hmmm, I bet they based their show on my video. Let's ask them.

  • wbeaty fight till you are blue in the face, you are wrong.

    It's in fact air pressure breaking the bottle, NOT the liquid

  • > wbeaty fight till you are blue in the face, you are wrong.

    It's not fighting, it's me pointing out stuff, and you ignoring it. With fingers in your ears, all discussion is pointless. So my comments are aimed at the audience. Not you.

    If you hit the bottle so that the top is sealed by your fist, the "bubbles" appear, and the bottom shatters. Is there high pressure above? No: if you hit the bottle without covering the top at all... same results: bubbles appear, and the bottom shatters.

  • Then make a video and prove it.

    Covering the top has nothing to do with the sudden burst of pressure created by the air being forced into the liquid, EXPANDING TO SEPARATE itself creating the momentary burst of pressure between the water, air and the bottom of the bottle.

    Guess what?

    The water is momentarily sealing the air that gets trapped from the open cavity at the top so the top of the bottle being sealed or not is irrelevant. You're just creating a small, momentary pressure cavity.

  • > Then make a video and prove it.

    To start fights, the Troll's typical ploy is to angrily adopt a fixed belief, then use hostile namecalling to "defend" it. They cannot be swayed, because their only real goal is insult and one-upmanship.

    It's not a new problem. From the year 1806:

    Misery of Social Life #15, "To be obliged frequently to meet in company a man who opposes every remark for the purpose of starting an argument, in which he is always more vociferous than convincing." J. Beresford

  • Turns out I was right, the "water hammer" theory is both incorrect and stupid. It is in fact a result of air compression/expansion as proven on the show "Time Warp".

    The air travels down into the liquid momentarily, expands to separate from the liquid and causes a momentary increase in downward pressure thus bursting the bottom out.

    Check out the Time Warp episode showing what actually occurs.

  • > Turns out I was right, the "water hammer" theory is

    Go listen to the time warp episode. They explain it correctly:

    "I'M PRETTY SURE THOSE AREN'T BUBBLES"

    "IT"S A CAVITATION, IT'S JUST LIKE A BUBBLE, BUT IT'S A BUBBLE OF VACUUM"

    "WARPED AT 10000FPS WE CAN ACTUALLY SEE THE VACUUM FORM ON THE BOTTOM."

    "THE LIQUID RUSHING TO FILL THE VACUUM, AND JUST BLASTS OUT THE BOTTOM"
