Air Face
 

Supplies: A flexible clear plastic tube at least a yard long, colored liquid such as Kool-Aid, liquid Jell-O or lemonade and a ground covering.  Better to play outside.

Put the liquid inside the tube and have two youth stand at each end of the tube.  The idea is for each to blow into the tube as hard as they can for as long as they can.  The person who gives up first will inevitably get Jell-O on their face.
