Answer 2

Get a clean 1 or 2 gallon metal container with a screw top cap. Put an ounce or two of hot water in it and place in hot sun without cap!

Put the cap on tight and immediately place in a very cool area. Soon the metal container will be crushed because the hot water vapor created by the container being in the hot sun will condense back into liquid leaving a partial vacuum in the sealed metal container.

The weight of the air outside the sealed container will crush it inwards.
