Tin of heat sensitive putty that changes colour in your hands.
Mould, stretch, bounce and even watch this putty melt as you play with it.
The warmth from your hands causes the putty to change colour, only reverting back to its original shade when it is left to cool down.
Available as four assorted colours including light purple that turns to blue, purple that turns to pink, orange that turns to yellow and green that turns to lime green.
