Crazy Aaron's Thinking Putty 4" Tin - Hypercolor Fire Storm
This color change is out of control! Crazy Aaron Hypercolors putty works beautifully as a fidget or sculpting material, but watch things heat up...literally! Pigments in the putty react to the slightest temperature change, even from just the heat of your hands. For extreme color change, pop it in the freezer or a warm bowl. Fire Storm colorway is intense and turns from a deep fiery red to a flickering flame yellow.
