I've seen a "minute to win it game" with water balloons played at a picnic before and it would work well at a pool party for kids, too!

Each team of 3 or more stands in a straight line about 6-10 feet apart. There are two buckets at each end, one of which contains dozens of pre-filled water balloons, and the other bucket starts off empty.

Start the timer for kids to gently hand toss each water balloon down the line in order to ultimately transfer as many water balloons from bucket A to bucket B. Watch a few balloons burst along the way but it's fun! Plus, everyone is wearing swimsuits anyway, so getting wet is no problem!
