I wish I had found this post on Sponge Ball Water Fights sooner! Over the weekend, we tried to have a neighborhood water war with water balloons. After spending 30 minutes filling water balloons my fingers hurt & were water logged so I was a little upset when it took the kids 10 seconds to pop all the water balloons and then start asking for more! I finally gave-up on the water balloons and we got out the water guns & hose. The sponge balls are a great alternative to water balloons & you can reuse them so it is even frugal!
