Get Your Science On: Can Crush
Last week, we showed you how atmospheric pressure can be used to give a giant “bear hug”. This week, we use atmospheric pressure to crush a metal can.
Water is boiled inside of the can, and this produces water vapor, an invisible gas which displaces the air inside of the can. The can is sealed and cooled, which causes the water vapor to condense into liquid water. This lowers the pressure inside of the can, causing the atmospheric pressure to crush it!
