These beads react to UV light and turn from white to strong colours over about 1 minute in bright sunlight or UV illumination. The rate of change is slower as the UV intensity falls. Beads return to white when in the dark and may be reused over and over again. Useful in projects designed to investigate the effectiveness of sun-screen creams etc.
