Get everyone wet!
Great Leader vs. Kids Game and everyone can get wet.
Have all the leaders line up at the front of playing area and all the kids gather together about 10 to 15 feet away.
Each leader throws a water balloon in the air above the kids for the children to try to catch. If someone catches it they get to choose a leader to throw the balloon at.
If nobody catches it, it will either break on the ground soaking the kids, or the leader who threw it gets to toss it at someone.
