Build a Balloon Powered Car
Ask a child to describe science in just one word, and you’ll probably hear “fun!” To young kids, hands-on science activities satisfy natural curiosities and are motivating, almost magical feats.
But science isn’t just about experiments that yield magic-like effects. It’s also about using knowledge to solve some of the world’s toughest problems. In today’s energy crisis, we're constantly looking at the science behind our sources of energy. Where does power come from, and how can we use it efficiently? Explore some of these big energy issues with your kids by putting on a jaw-dropping demonstration of an ultra-efficient air-powered car!
What You Need:
- Clean, dry, half-gallon milk carton with the top cut off, cut in half along the length of the carton
- 4 spools (or substitute your own items for wheels, such as large bottle caps)
