Water Balloon Volleyball
There are two teams, and each teams gets a sheet. Everyone on the team holds a corner or side of the sheet so that it is horizontal and flat. Put a water balloon on the sheet of one team. Using lots of teamwork, bounce the balloon on the sheet until it flips over the net. The other team must catch the water balloon in their sheet and flip it back over the net. For children that are littler, use small tablecloths.
