What you need:
* Rubber bands
1. Cut sponges into thin strips using scissors (we used two sponges per ball).
2. For each ball, collect sponge strips in your hand and hold at the center; wrap rubber band around the strips two to three times to secure. Repeat to make however many sponge balls you’d like.
3. To play, divide sponges among buckets and fill with water. Divide into teams. Line up on opposite sides of the lawn, beach or wherever you’re playing. When you’re hit with a sponge ball, you’re out!
TIP: Use different color sponges for each team.
