Have kids fill a large cup 1/2 way with the crushed ice.

Add 1/3 cup salt to the ice.

Place the smaller cup into the middle of the larger cup (try not to touch the ice with your fingers)

Blow into the small cup

Pretty cool! The cloud is formed because your breath contains water vapor, a gas.  When the vapor hits the cold air in the smaller cup, it turns from a gas to a liquid forming tiny drops of water, making a cloud form.
