FIRE STORM
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.
