Smart Colour Changing Putty
This Putty changes colour by using your own body temperature, you can watch this brilliant blob change from purple to blue 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.
