After inflating 10 balloons to the point of popping with my legs crossed at the edge of the bed, I pop each of them. I pop one by sitting on it until it pops, and all the rest are done by stepping on them with my lovely feet. I press down on them hard, feet arched. It's a bit of a struggle at first to press them to this point without moving, but I eventually get the hang of it. POP! Enjoy :)
