Stomp Rocket Jr. Glow

The Original Stomp Rocket Jr. Glow is so much fun that kids won’t even realize they’re learning. With this toy, children ages three and up will explore STEM concepts like physics as they launch glow-in-the-dark rockets high in the air.

The Stomp Rocket Jr. is easy to assemble and even easier for kids to master. All they have to do is run, jump, and stomp on the launch pad to send the glowing foam rockets flying into the sky—up to 100 feet!

"The foam rockets are very soft, so they won’t do much damage if they hit anyone below the neck. Although the manufacturer notes that the toy is good for indoor and outdoor play, we really only recommend the latter, as we had a few close calls with our TV and other objects."—Danielle Directo-Meston, Product Tester
