My Two Cents on Bunch O Balloons

My kids love these. They are always a hit. It’s part of summer and being a kid, and learning to throw a good water balloon…and avoid them! We also use them to all kids of wacky things like tie them up and see who can pop theirs [fill in the blank with a spoon or whatever], or balance them on a spoon and race like an egg race, or use them with the corn hole boards and toss them…they are fun!
