Turn big science ideas into action with CrunchLabs Crunch Kits, inspired by viral experiments from former NASA engineer and creator Mark Rober. Each collectable kit combines science, engineering and problem-solving with challenges kids can build, test, tweak and try again.
Discover three CrunchLabs toys to collect: the Egg Drop Challenge, Turbo Trick Planes and Slime Prank Lab, each offering different experiments and ways to play. Kids can explore scientific principles while chasing surprising results, testing ideas and discovering what happens when brainpower meets action.
Every Crunch Kit includes QR code access to How-To-Play videos where Mark Rober guides kids through the challenge step by step. With explanations covering the science and engineering behind each experiment, these STEM activity kits make learning feel like an adventure.
Suitable for ages 6 and older.
