Professor Marty's Genius Putty - Chameleon

Professor Marty's Genius Putty Chameleon changes colour in response to temperature, which is the whole trick and the reason it holds attention longer than ordinary putty. Warm hands, cold surfaces and a bit of stretching all shift the shade, so the play is as much experiment as fidget.

It works as a sensory toy for children and as a desk fidget for adults, stimulating the imagination and encouraging tactile exploration in both cases.

Putty like this ends up in pencil cases, on office desks and in party bags, and it costs little enough to buy several at once. Please check the packaging for age guidance and care before use.
