Professor Pengelly's Colour Changing Putty ��� Radiant Purple to Pink

Made for the fingers of creative thinkers, Professor Pengelly’s Putty can be bounced, squeezed, twisted and sculpted to create all sorts of crazy shapes. This purple putty is heat-sensitive, meaning that it reacts to heat by changing colour. As you play with the putty, the heat of your hands will transform it from radiant purple to a shocking shade of pink. Fiddling with the putty is scientifically proven to relieve stress and help you focus, making it great for keeping on your desk. The putty comes in a storage tin to stop it drying and provide endless hours of fun.
