Fluor minerals*** WARNING **** THIS PRODUCT IS NOT AVAILABLE ANYMORE ***** OPGELET **** DIT PRODUKT IS NET MEER LEVERBAARa box with fluor minerals . All kind of different colors. UV light needed to see color change. When some minerals are exposed to ultraviolet radiation, the electrons orbiting the nucleus can be excited to such extent that they jump to a higher energy scale. This is an unstable condition and when the electrons return to their stable state the excess energy is emitted as light. The colour of the light is determined by the difference in energy between electrons in the higher and lower energy electron shells.
