My oldest tried cotton balls first and the egg survived. My youngest used bubble wrap and went full mad scientist. These are the padding supplies that actually kept eggs intact from 20 feet up.
















The container is where kids get really creative. One of mine used a shoebox, another taped together plastic cups. Having a variety of options on the table lets them problem-solve instead of just copying each other.














Nothing falls apart faster than a kid's engineering project without enough tape. I learned this when my son's first design exploded on impact because he used two pieces of masking tape. Stock up.
















When my middle kid realized she could slow the fall instead of just padding the egg, the whole challenge shifted. Parachutes turned this from a padding contest into actual physics thinking.
















Scissors, rulers, and markers turned this from a tape-and-pray situation into actual designing. Once my kids started sketching plans before building, the eggs started surviving.
















Three kids, multiple drops, and at least a few cracked eggs means your driveway will look like a breakfast buffet. Plan for the mess and you'll actually enjoy this instead of dreading it.
















Once I added a scoreboard and started filming the drops, my kids went from casually tossing things off the balcony to full-on competitive engineers. Keeping score made the whole thing repeatable.
