<p>Undeniably dangerous, a firestorm is a wildfire that burns so intensely it creates its own storm system. This natural phenomenon produces exceptional fires that blaze and gust with gale-force winds in all directions. A much safer alternative, Firestorm Thinking Putty® glows a fiery red that changes to flame yellow with just the heat of your hands.<p>As part of the Hypercolor® Collection this color changing Thinking Putty® is heat sensitive, meaning it starts one color and changes to another through heat transfer. The more you play the more the color will change!<p>Thinking Putty® helps build hand and finger strength through a fabulous tactile play experience with unique, unexpected properties and provides relaxing, yet stimulating interaction for anyone with sensory integration issues.<p>Crazy Aaron's putty is non-toxic, won't dry out, and won't leave a sticky or slippery residue on your fingers, so it's great for stretching, molding, bouncing, tearing, popping and playing by kids and adults alike.<p><ul></li>Includes tin with 1/5 lb.
