This one is pretty self-explanatory: dodgeball... but with water balloons. Just don't aim for people's faces.

If you're not bothered by the idea of actually eating something, play this sandwich making relay race game. Teams line up beside a table and work together to make a sandwich FAST (one person spreads the mayo, one person adds the meat, etc.). When the meal gets to the end of the line, the last person has to eat it.

Who doesn't like playing with a sling shot? It's just not something that fades with age. In this game, you use one to launch wet sponges at your teammates, who catch them and wring them out into a bucket. The team that fills their bucket with water first, wins.
