Hypercolors: These are the heat-sensitive putties that change color before your eyes; they never cease to amaze.
Thinking Putty Sunburst hypercolor is thermochromic – meaning just a touch from your hands or a warm coffee mug will reveal a new “hot” colour. Allow it to cool off or stick it in the fridge! Then the “cool” colour will be restored.
Twilight – “Jumpstart your day with some sunshine! Sunburst Thinking Putty’s vibrant orange shifts into an awakening yellow with the touch of your hands or the warmth from your coffee mug.”
