Why We Love It

The Crystal Hedgehog is one of our bestselling science kits, and it is small but mighty. An easy activity that takes only an afternoon to start, but wait - leave that hedgehog out, and in about 24 hours it's grown a carapace of colorful crystals! Kids love mixing the ingredients and observing the changes.
