Fat Brain Toys Crystal Growing Hedgehog - Green - Chemistry Activity for Kids 10+;

Become a master of minerals!

This hedgehog has a big problem: it doesn't have any spines! And the only way it's ever going to get some? SCIENCE!

Following the detailed instructions, young scientists simply mix the special solution into a container of boiling water and then set the poor, spineless hedgehog into the mixture.

One day later and - (insert drum-roll) - Ta-da! Covering the hedgehog's entire back is a huge, spiky cluster of glimmering, colorful, sturdy, solid crystals!

Experience the playful side of science with the Crystal Growing Hedgehog, available in five fun colors.
