Recruit 5 girls and 5 guys or however many students you want to play this game. Bring them up front and pair them in groups of two with one guy and one girl per group. Guys lay down on their backs and hold the base of the cup to their forehead. Their teammate stands over them and cracks the egg with their hands attempting to drop the content of the egg into the cup as it spills out. Most of the egg will wind up on the participants face. It’s rather tricky. The team with the most egg in their cup wins. Enjoy.
