Balloon Defense

Two bags of balloons, each a different color. Form two teams of 25 to 50 each. Each team must defend its treasure (a pile of balloons) while attempting to steal or destroy the other team's treasure. Use one color of balloons for one team, and another color for the other team. Designate a time period (5 to 10 minutes) to play the game. When the time ends, each team's unpopped balloons count 100 points each. Stolen, unpopped balloons count 200 points each.
