The Glowhouse Colour Changing Smart Putty Heat Sensitive Galactic Green

• Heat Sensitive Colour Change

Product description 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! Directions 1. Shape the putty as you like. 2. Stretch it to see how much you can do it without breaking it. 3. Bounce putty on the floor or soft surface. 4. To change color, use the heat of your hands or put the filler in a heat source, such as a cup of hot water. Watch the putty change from deep green to light green and vice versa.
