Crystal Hedgehog Grow Kit
Learn about chemistry in the cutest way possible by giving this plaster hedgehog a back full of colorful, elongated crystal quills!
It's easy--just dissolve the crystal powder in water, place the hedgehog with the plaster base in the solution, and wait 24-48 hours. Each hedgehog is unique, so no two crystal kits will look the same!
Each kit comes with everything you need to grow quills: crystal powder, a growing container, a stir stick, a plaster base, a hedgehog figure, and instructions. (Just add water!).
For ages 10 and up; adult supervision required.
