Crystal Growing Hedgehog – Fun Science Toy

Fat Brain Toys offers a large catalogue of toys for children of all ages and abilities.  One of my favorite things about their website is that you can search for toys based on different special needs.  When I selected Sensory Integration Disorder (also referred to as Sensory Processing Disorder), the Crystal Growing Hedgehog popped up.  I read its description and thought it would be fun to write about!

The Crystal Growing Hedgehog is a fun science toy that helps children “become a master of minerals!”  Unlike your usual hedgehog, this toy has no spikes – until children create them.  Here’s how it works:

“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!”
