Thinking Putty is great for children and adults. Terrific for keeping hands busy, plus offers a great option for stress relief and relaxation. Thinking Putty can be shaped, kneaded, stretched, bounced and much more. Extra soft and pliable. Created to mimic the effect of a giant swell, Tidal Wave Thinking Putty comes with a powerful magnet to help you create incredible effects. Charge the putty with the magnet and watch as the iridescent blue crest moves toward it in an invisible magnetic field. You'll even see ripples on the surface just like the sea. 3.2 oz. tin.
