What happens when you cross a carnival fish pond with a water fight? You get our Sponge Ball Gone Fishing Game! Sponge balls are a summertime favorite at our house, and they’re simple to make using this sponge ball tutorial. Add a new twist by creating a fishing pole from a dowel, string and clothespin. Take turns being the fisherman or the one to clip the sponges onto the pole and toss them back over. Either way you get wet!
