Make fun “sponge balls” from dollar-store sponges. Cut two rectangular sponges lengthwise into four pieces each, then stack the strips into two layers of four pieces each. Wrap a rubber band tightly around the midpoint of the stacked sponges. “Fluff” and pull the sponge strips until you have a ball shape.
To play, give kids a bowl or bucket of water to dip the sponge balls into. Wet sponge balls are great for tag, target practice, or just tossing back and forth between kids! Watch this Martha Stewart video for a more detailed tutorial.
