The Glowhouse Colour Changing Smart Putty Heat Sensitive Galactic Green

Putty that you can mould? Check! That you can stretch? Check! That you can bounce? Check! This putty has all the fun of the original, but with an added extra: it’s Colour Changing Putty! Using nothing more than your own body temperature, you can watch this brilliant blob change from Deep Green to Light Green 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 a young scientist or anyone that enjoys mucking about with this marvellously malleable material! Colour Changing Putty comes in its own storage tin and is available in Galactic Green!
