EXPERIMENT: Take a tin-can having an airtight cap (screw cap). Remove cap and boil somowater in it, so that steam comes out and in this way air from inside goes out. While boiling replaces the cap and allows it to cool. Vapours inside condense and form water creating a vacuum above them. We see the can crumbles due to air pressure from outside.

You can crush an open aluminum can with your hand. When you squeeze on the can, the pressure outside becomes greater than the pressure inside. If you squeeze hard enough the can collapses. Usually, the air pressure inside an open can is the same as the pressure outside. However, in this experiment, the air was driven out of the can and replaced ...

The big picture? Air goes from high air pressure to low air pressure (or more air to less air). If something gets in the way, it makes a push. How does this relate to the crushing can? The steam pushes out all the air in the can; notice steam is coming out? It just pushed out all the air.

So in summary, a can will get crushed when the pressure outside is greater than the pressure inside of the can. Also, the pressure difference must be greater than the one the can is able to withstand.For example, we can easily crush an aluminum can with our hands. When we squeeze the can, the pressure outside becomes greater than the pressure inside.

The outside air pressure is one atmosphere. The pressure in the can is one atmosphere as long as there is a way for air to come in and out, and as long as you heat the can gradually. After the can is crushed, the gas pressure in the can is one atmosphere again (once water has had time to flow in and out).
