CrunchLabs by Mark Rober Crunch Kits

Mark Rober has inspired millions with his epic engineering videos, and now kids can get hands-on with the same kind of experiments at home. CrunchLabs Crunch Kits turn big science ideas into fun, buildable challenges: build something, test it, see what happens, then redesign it to make it better. It's real STEM learning through play, with a big "aha" moment in every box.

Every kit has multiple ways to experiment, so no two runs are the same, and a QR code links to How-To-Play videos with Mark Rober, who guides you through each challenge and explains the science behind it.

The 3 Crunch Kits in this assortment

Egg Drop Challenge Inspired by Mark Rober's legendary Egg Drop from Space experiment. Build a protective frame around a reusable toy egg filled with yolk slime, add a parachute and drop it from different heights. Will your egg survive... or SPLAT? Redesign your frame to balance strength, stability and shock absorption, add household materials for extra builds, or even try it with a real egg. Includes: 1 toy egg, 1 egg cup, 1 parachute, 3 landing balls, 1 slime bag, 73 connectors, 2 googly eyes, 1 instruction manual.

Turbo Trick Planes Build a plane launcher, then fold paper planes to recreate 5 flight designs, including the Dart, Drift, Trick and Stunt planes. Swap the power bands to change speed, launch angle and flight performance, then master the tricks. A brilliant intro to aerodynamics. Includes: 1 toy plane launcher, 1 plane clip, 3 power bands, 5 paper planes, 1 tool, 2 googly eyes, 1 instruction manual.

Slime Prank Lab Science meets mischief. Experiment with slime recipes to change thickness, texture and stretch, then build prank gadgets: a Snot Pump that dangles a slimy "booger" before snapping it back up, and a Fart Speaker that plays wet and dry fart sounds. Includes: 1 toy pump, 1 fart speaker, 2 slime bags, 3 nozzles, 1 tool, 2 googly eyes, 1 instruction manual.

Why kids (and parents) love it

CrunchLabs Crunch Kits make science feel like play. Kids learn problem-solving, engineering thinking and the scientific method (build, test, tweak, repeat) without it ever feeling like homework. With Mark Rober's videos guiding the way, they're ideal for curious kids, YouTube fans, birthday presents, Christmas gifts and rainy-day projects.
