How to Play: Water Toss
What you need: You need resealable plastic bags and buckets of water.
How to play: Dip each bag into a bucket of water to fill it up and then seal it. Make enough bags for each player and to have back-ups. Establish a line, which players can toss the bags across at each other. Divide the children into two teams, and put each team on opposing sides of the line.
The rules: Players will throw the bags at each other. If a player gets hit, she is out of the game. Play continues until only one player remains.
How to win: The last player remaining is the winner.
What else you need to know: Using bags rather than balloons is great for kids with latex allergies.
