Our balloon balls are made to bounce! The trick is, to blow them up as tight as you can, and just when you think you can't get any more puff into the balloon, give it one more blow. The tighter your balloon ball is, the better it will bounce!
We use a helium-quality balloon, as they last a whole lot longer than other balloons we've found. However, you can use any balloon you choose.
Please dispose of the balloon carefully and environmentally thoughtfully.
