Divide your group into two teams and have them sit facing each other, about 30 feet apart. Take a bunch of balls and use them as ammo to hit a balloon target set in the middle of the room. The goal is to get the balloon to cross the other team’s line by hitting the balloon with balls. No hands and no blowing the balloon. It is fun to watch because students are all focusing on the balloon and they get blindsided by flying balls. It’s awesome.
