Muscle Beach

Ask the guys in the group to bring an oversized sweatshirt. Don’t tell them what they’ll be used for. Also bring about 10-15 balloons for every 4 kids in your group.
Make teams of four (at least one guy on each team). Have each team choose a guy representative and ask them to put on the sweatshirt. The object is to make a “muscle man” by blowing up, tying and stuffing as many balloons into the shirt of the guy until he is as “muscular” as possible. Give them 2 minutes.
Determine the winner by a panel of judges. The first guy to break all his balloons by himself is also declared a winner.
