- Inexpensive flip-flops
- 300 water balloons
- Place 3 water balloons in the same direction and tie them together with the fourth balloon. Continue with the fourth
balloon, double knotting it onto the flip-flop strap.
- Repeat until each flip-flop strap is covered. Balloons can easily be slid up and down the strap until the desired amount is achieved.
We used approximately 150 water balloons per flip-flop.
