Blast off with science that's good for the planet. The 4M Green Science Rocket Kit turns a recycled magazine and two plastic bottles into a real air-powered rocket that launches up to 80 feet into the sky — no batteries, no waste, all wow.
Kids learn about air pressure and propulsion while upcycling everyday materials into an epic backyard experiment. It's STEM learning disguised as pure launch-day thrill — build it, pump it, and watch it soar again and again.
