Colour Changing paint for your Car!

The people who dreamed up self healing paint a few years ago have now come back with a paramagnetic concoction, which is supposed to enable motorist to change the colour of their car.

This is done using a special polymer containing paramagnetic iron oxide particles and an electrical current. The electrical current adjusts the spacing of small crystals with in the iron oxide particles to reflect light differently and change colour all at the touch of a button.
