Instructions
Using strong string, hang a balloon from the ceiling of a cleared room. It should be long enough to reach your hands.
Have your group stand or sit in a circle around the balloon and hit it to one another. You can do this to music for a little more fun.
This game can go on for ages and promotes laughter and giggles as the balloon bounces all around.
This seems like something that will definitely get little kids laughing and having a great time.
