Have fun with the Heat Sensitive Hypercolours Putty, a thermochromic putty that quickly changes with the touch of your hands or a warm coffee mug to reveal a new "hot" color. To reset it, just allow it to cool off or stick it in the fridge and the "cool" color will be restored.
The tin measures 10cm x 3.5cm and contains 90 grams of putty. Suitable for ages 3+
