This is a great summer intro game, especially for inducting new seventh graders or any group of totally new students. As students arrive at your event put their name on a water balloon. When everyone has arrived distribute the balloons and make sure no one has their own name. The trick is for them to soak the person whose name is on the balloon they recieved while not getting hit by the one with their name. Some students are sneeky and follow the person around. Some have to ask many people who the person is, but that is dangerous because they never know who has their balloon. The last one standing gets a prize.
