Balloons pop if you stand on them, right? Not if you do it just so! Here's how your child can perform this fun feat.
First, blow up the balloons to equal size. Set a rimmed baking sheet on top of them, bottom up.
Now have your child position one foot in the center of the sheet -- thereby evenly distributing the pressure -- and then slowly step on with her full weight. It's a wobbly undertaking, for sure (an adult should serve as a spotter), but our testers reported that even a 125-pound parent climbed on without a pop.
