You need a clear indoor space for this one like an empty classroom or fellowship hall. Set two chairs back to back about eight to ten feet feet apart. Drape a rope or a piece of fabric across the chairs for the net. The ball is a balloon. Volleyball rules apply except everyone is seated. You have to stay on the floor to hit the ball… no getting on your knees. I make the general rule that their butt has to be at the ground. My middle and high school kids love this one. It’s funny enough for the laid back kids and just enough competition for the jocks to stay interesting for all.
You need 3 plastic eggs for every player, a roll of masking tape and a pen. Number your eggs in sequence. I used the masking tape so I could write on the eggs. There will be three eggs with a 1 on them, three eggs numbered with a 2 and so on. Hide them in a designated area or in several rooms side by side. As young people arrive put a number on them with the tape to correspond with each set of eggs. For example, I had 6 middle schoolers at a meeting. I hid 18 eggs. The kids were numbered 1 through 6. The rules are simple. They have to find their eggs. If the egg they find doesn’t have their number on it they have to leave it. They can also choose to rehide the egg. However, adults circulate around the room. If they catch someone with an egg that doesn’t match their number they have to surrender one of their numbered eggs. It’s a blast for the kids and the leaders.
