Colour Changing Putty 

Stretch it! Mould it! Bounce it!  The perfect gift for any young scientist.

Please note that the retail packaging may vary from the picture.

This putty has all the fun of the original, but with an added extra, it’s Colour Changing. Using nothing more than your own body temperature, you can watch this brilliant blob change colour and back again. How does it work? Well, the boffins in our lab have been working with reversible thermochromic pigments, which are coloured molecules that react to changes in temperature. Our Colour Changing Putty is the perfect gift for any young scientist or anyone who enjoys mucking about with this marvellously malleable material. Colour Changing Putty comes in its own storage tub and is available in 3 colours.

Thanks For Viewing & Buy With Confidence.
