Water balloon fights can be a fun activity for kids on hot summer days. But, it is hard to pick up all the balloon scraps and they can take up to six months to decompose. No problem – our intern Lauren Langdon has discovered a fun alternative.

A green alternative to water balloons is buying large sponges or repurposing old sponges. Not only do you avoid the time consuming process of filling up water balloons, but also these sponges can be reused for years – saving you money.

If you have a rain barrel, you could soak the sponges in this water, making this an even more eco-friendly option!

Instructions:

  1. With a pen and a ruler, make five lines lengthwise on three sponges, each 1/2 inch apart.
  2. Use scissors to cut the sponge, using the lines as a guide, into six pieces. Repeat with the other two sponges.
  3. Lay strips on top of each other in three layers, five to six to a layer. Cinch them across the middle with a piece of string; knot it tightly. Fluff pieces out into a ball.
