Thinking Putty is an amazing material - stretch it, bounce it, mould it, snap it, fiddle with it! UV Reactive Thinking Putty reacts to UV light! 'Draw' on the putty with the mini UV torch light included, and the putty will magically change to blue where the light has been. Great for writing messages and drawing patterns. The blue colour disappears and the putty goes back to normal after a short time. Choose from 'Mystic Glacier' (light green putty turns purple under UV) or 'Foxfire' (white putty turns blue under UV light).
For ages 8 years and upwards. Tin measures 10cm in diameter and contains 3.2 ounces of putty plus a mini UV flash light which comes with batteries supplied.
