Just as an evening sky melts into the dark of night, Twilight Thinking Putty’s deep purple color disappears with a touch of heat to reveal a fluorescent blue complexion.
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. Please note that this product may contain colourants that can stain. Putty may stick to clothing, hair, eyebrows, eyelashes and fabric.
