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.
Heat Sensitive Thinking Putty really makes it mark. Heat sensitive Thinking Putty is thermochromic – 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! You can even do tricks with Heat Sensitive Thinking Putty! Each tin comes with 90g of putty.
