Has everyone done this experiment where you heat up water in a coke can and flip it over into cold water and the can collapses? If you haven't you should - it's cool.

I do it for my students. Make sure the can is OPEN.

Cool, I'm going to try this later. My wife has a few cans of some crappy natural soda that the world could do without. I assume this is because of the carbonation?

Nope, just water involved - you're using an empty can. It's an example of "nature abhors a vacuum".

Reminds me of Boy Scout camp many years ago. It's family day and this kid's father puts a can of beans on the fire--unopened...

His son is sitting by the fire with a leg in a cast.

Hilarity results /images/graemlins/laugh.gif

Put about 2 oz. of water in the can. Heat it up so that the water boils. Quickly grab the can and invert it into a pan that has 1 inch deep of ice-cold water in it. The can will squish with a "frooomp!!". Try not to burn yourself. I've done it with my bare hands, but the can does get a bit hot, and the steam coming from the can is really hot.

If you are really feeling sassy, do it with an old 50 gallon drum.......

Not at all. You need to empty the can and add a little water. By boiling the water in the can, you basically evacuate the can except for a few molecules that are moving around super fast and banging into the walls of the can. When you invert the can and put it into the ice-water, the molecules that were once moving super fast slow down because they get cold. When that happens, the pressure in the can drops, causing the can to get squished by the pressure in the room.

Oh. I would have spent two hours this afternoon wondering why my full can of soda wasn't crushing, all the while muttering to myself, "man, those OOT guys are full of [/i][censored]."

I hope people at the University of Arizona College of Engineering don't read 2+2. They'll hunt me down and take away my MS for being such a retard.

Its ok, you would have never gotten that far since your full can would have exploded when you tried to heat it up.

Exactly. Never did feel like much of a "master of science". I don't even have a cape or a mask.

Wow, man. I'm appalled that you don't know about PV = nRT.
Don't you work with pressure vessels at all as a civil engineer?

Q: What's the difference between Mechanical and Civil Engineers?

A: Mechanical Engineers make weapons. Civil Engineers make targets.

Knowing PV=nRT is one thing (which I do, and have since like 10th grade, which has nothing do with being a CE).

Actually thinking about it and applying it in a particular instance is another. The OP was about crushing coke cans, and I retardedly assumed it was full coke cans.

None of the above vindicates me from being a horrible engineer, which I was without a doubt, and which is why I'm now doing other things.

I've always liked the one where you put a chicken bone in a glass or can of coke.

Makes you wonder just how good it is for you to have in your body.

This thread keeps coming back, so I keep thinking abiut this after seeing the tanker cars implode: what would happen if you filled a regular car with steam during a hot day and then allowed the car to cool overnight?
