- Slovenian6474, on 04/24/2008, -10/+349This also happens when Magneto sneezes.
- inactive, on 04/24/2008, -24/+315Reminds me of the United States Dollar!
- kl78229, on 04/24/2008, -4/+178Be sure to vent yourself occasionally as well, to avoid this happening to you.
- chris4404, on 04/24/2008, -6/+92How long have you been waiting to tie that piece of information to a Digg story?
- DigablePlanet, on 04/24/2008, -5/+61Homer Simpson forgot to vent the tank. Probably changing his moo-moo or trying to find the "any key"
- thcobbs, on 04/24/2008, -3/+56Actually, there is no suck... only a push due to pressure differential....
So in this case, the atmosphere blows. - cybrspin, on 04/24/2008, -6/+58wow thats wild.
- Kikkoman, on 04/24/2008, -6/+50That's a tank filled with kittens :(
- Negligence, on 04/24/2008, -1/+38It's actually quite common to setup two video cameras to watch a non-moving tank, and have people sit around idly for hours hoping that it crumples. I don't know why they do it, but they do. Anyone else want to chip in to explain how this was a total coincidence caught on tape?
- vclortho, on 04/24/2008, -1/+36I love all the Digg physics experts in here...
- thcobbs, on 04/24/2008, -1/+35I'd guess roughly 10 years?
- thcobbs, on 04/24/2008, -1/+34Yes, we know. Light a match or somethin', will ya'?
- clesch, on 04/24/2008, -4/+37I had to read that description four times until I understood why this happened.
- pharekyz, on 04/24/2008, -3/+35I bet you are a riot at parties.
- Nougat, on 04/24/2008, -3/+35I have more than one piece of information. Often, a bit of information I have is somewhat relevant.
And more like 12 years. - jerrycan, on 04/24/2008, -5/+35I doubt she could suck as much as your comment.
- Impeller, on 04/24/2008, -1/+30Can't vent at the office, implosion coming soon...
- Nougat, on 04/24/2008, -3/+31Gas tanks on late 90s BMW 7 Series used to do that, too, though not as quickly.
- Mr.Gone, on 04/24/2008, -11/+38See what's actually happening is there is a force in the world called "God Pressure" It's the force that the lord applies to all things he created to keep them in one spot. Think of it as the most comforting hug you will ever feel, but you feel in every second of your life. Now this God Pressure sometimes needs to crush things to protect it's creations that it loves the most. So when it sees evil, in this case this tanker, it crushes extra hard. Don't worry though, God made you, so he won't crush you, unless he starts hating you, or you go where there is too much God Pressure, like at the bottom of a mid oceanic trench.
- LordofChaosIori, on 04/24/2008, -1/+27Stop correcting him people, it was a clever joke, let's take it as one.
- 80hd, on 04/24/2008, -1/+27Thats an expensive experiment.
I used to work at a plant that built tank cars and they sell for 80-120k! - woohhaa, on 04/24/2008, -1/+25I vent constantly.
- briangig, on 04/24/2008, -2/+26love to see this in one of those 4000 fps videos...
are they pumping whatever is in the tank out or just letting gravity pull it out? If its just gravity wouldnt the flow stop when the pressure reached a certain point in the tank? - jcaino, on 04/24/2008, -2/+26as the interior air cooled, it caused a pressure drop. eventually the pressure drop was large enough to overcome the pressure rating of the tank. crushed with atmospheric pressure! almost like creating a vacuum inside.
- doople, on 04/24/2008, -1/+21That may have been a tank that had exceeded its service life, and was headed for recycling anyway. Why not have some fun first?
- 1randomnumber, on 04/24/2008, -14/+33Physics is Phun!
- rompom7, on 04/24/2008, -4/+23Hot gas, has a lot of energy, the atoms are spread far apart and can move around freely. When the gas cools, the atoms lose some of this energy and they move closer together. So a container filled with hot gas will have a lot less gas atoms in it than a container filled with cool gas.
Since the once hot gas that filled the container has cooled, it has less pressure inside the tank. The pressure drops so low that the outside pressure of the atmosphere is enough to crush the tank.
I thought it would happen gradually, but as soon as the weakest point gives way the structural integrity of the whole thing collapses. - cawpin, on 04/24/2008, -3/+22No, the CHANGE in the temperature inside the tank is what crushes it. Warm air is less dense than cold air so it takes up more space. When the tank is hot there is less air in it. When it is sealed and the air inside cools, and becomes more dense, it takes up less space and forms a vacuum inside the tank. If this vacuum is strong enough this picture is what happens.
- inactive, on 04/24/2008, -3/+21Where? I'm looking to the right of my screen but all I see is whitespace.
- stephenmeb, on 04/24/2008, -2/+20It's close enough to a rickroll, I was hoping to be enlightened.
- cr3ative, on 04/24/2008, -18/+33Unfortunately, it's not atmospheric pressure that caused this collapse as the video might have you believe.
This longer video provides a little more explanation than the liveleak video (not a rickroll, either!)
http://www.youtube.com/watch?v=8H94sNT5UB4 - Akaji, on 04/24/2008, -1/+15Just do a round about the office, or go to the crapper to do it (check the stalls first, though...).
- HayString, on 04/24/2008, -1/+15Yea, "experts" alright.
- uruururr, on 04/24/2008, -6/+19if anyone wants to provide a better explanation for this... please do. is the tank imploding? its odd that theres a crowd standing around it laughing...
- waggowaggo, on 04/24/2008, -1/+13kittens with low kinetic energy
- crazyhorse13, on 04/24/2008, -5/+16*Gojira
- frasermoo, on 04/24/2008, -2/+12it is mandatory in many countries when emtying tanks to have mutiple video cameras and crowds of onlookers behind security tape.
- tradwolley, on 04/24/2008, -2/+12It doesn't shrink. A gas (including hot air) always expands to fill all the available volume. It loses kinetic energy as it cools which results in a drop in pressure, assuming the volume stays constant.
- dudeguy1234, on 04/24/2008, -0/+10No, sorry, I don't just go to the store and go, "Oh gosh, do I have a sack of rice? I might as well pick one up while I'm here!".
- breckinshire, on 04/24/2008, -0/+10That was the name of my band in college. We sucked!
- Scynet, on 04/24/2008, -2/+11The pressure inside can't somehow pull the walls of the tank towards it. The atoms can merely bounce off of things, thus pushing things, not pulling.. It's the external pressure (atmosphere) which constantly pushes the tank, and since there's nothing inside to push back, it implodes.
It's not wrong to say it sucks in my opinion, but it might create some misconceptions. - neil1492, on 04/25/2008, -0/+9http://youtube.com/watch?v=2WJVHtF8GwI
Liveleak wasn't working for me. - dudeguy1234, on 04/24/2008, -0/+87 Schrutebucks
- 11oops, on 04/24/2008, -0/+8His noodly appendage.
- gu0d, on 04/24/2008, -6/+14Dugg for Sirius - Alan Parson's Project
- DrDragun, on 04/24/2008, -0/+8It also makes you appreciate how strong a submarine's hull is. Atmospheric pressure is only 14.7 psi even if it were an absolute perfect vacuum inside that tank. Submarines can take a thousand psi of pressure or more.
- palmer, on 04/24/2008, -0/+8Still doesn't explain how you could empty the tank and NOT vent it. Without something to replace the drained material, how did it flow out?
- akilleen, on 04/24/2008, -1/+8She's gone from suck to blow!
- gurellia53, on 04/24/2008, -0/+7cuz he's wrong
