Double Duty Balloons

Add color and fun to your cooler by filling it up with frozen water balloons. They'll keep the snacks cool, and at the end of the day you can choose between two options: refreeze and use again, or, a killer water balloon fight. You can probably guess which option the kids will choose! Be sure you pick up any scraps of exploded balloons to make sure animals don't eat them. Find out more about this cool idea over at Brit + Co.
