Keva Contraptions Reactions Kits

With chain reaction kits, students become engineers and inventors, designing tunnels, ramps, tracks, and towers to set off exciting chain reactions. Precision-cut planks and unique components—like a bell, bowling pin, and toy car—bring STEM concepts to life as students experiment with balance, proportion, and stability. No tools or adhesives required—just creativity and problem-solving!

The included idea book jump-starts inspiration, but students may also design their own unique reactions. Includes 178 wooden planks, 8 dowels, 2 reaction balls, and more for limitless hands-on learning. Each plank measures 4-1/2"L x 3/4"W x 1/4"H. Accommodates 1-2 students per kit, or up to 8 students for a set of 4! Recommended for Lower Elementary and up.
