Overview
Body heat triggers the color shift in this putty, moving it from purple to orange to yellow as warm hands work it. It stretches, bounces, pops, tears and sculpts, then goes back into its tin.
Watching the color change while kneading makes it a calming desk fidget for all ages. Putty can work into fabric or carpet fibers, so it needs a hard surface for play.
Who it's for
Kids and adults who think better with busy hands get a quiet desk fidget. Families with very young children should supervise or wait, since putty is easy to mouth.
Pros and cons

Performance notes
Heat-sensitive pigment shifts color as the putty warms in the hands and returns as it cools. Its texture flows slowly when left alone and snaps when pulled fast.
