The light slowly phases through multiple colours giving you a gentle mood lighting effect throughout the optical fibre strands.
The glitter in the base also transforms the light that's shown on the surfaces that you place this cool fibre optic light near.
To get this optical marvel of mood-light-awesomeness going simply place 3 x AAA batteries (not included) into the base and switch it on. The lamp will then start cycling through all the colours of the rainbow. Give it a shake to have the glitter swirl around for extra visual effects.
