the . can

I did a lab called the collapsing can lab. It was pretty cool and i enjoyed it a lot. What we did was we boiled a can until steam started coming out. Then as soon as the can boiled, we took the tongs, grasped the can, and inverted it into the cold icy water. When the can was as hot as it was, and it was put in cold water, the can collapsed completely. How the can collapses is when the water is hot and the molecules are moving fast, they turn into steam. when the hot water meets the cold water, where the molecules are closer and more tight, the can collapses because when the fast moving molecules suddenly meet the slow moving molecules, they crush the can
