Okay, we admit it. These are kind of juvenile, and at first glance, they do very little for your brain cells. But these are Brainbows - colorful chemistry wonders that are a major step up from the old-school kind!
For starters, they grow up to 100 times their original size when immersed in water, and (most awesome of all) can be reused repeatedly. They are designed for bouncing, throwing, smashing, spitting from a straw, and other delightfully immature activities we have yet to think of.
Brainbows™ need 2-3 hours completely submerged in water to reach their full multi-colored potential as marble-sized spheres that are perfect for tossing, smashing, and anything else your child wonder can think of.
