The model comes in kit form - easy to make

The idea of this small model is to show that the white light we look

through is made up of the spectrum (rainbow colours). By using the solar cell near a light source the small rainbow disc will spin - the faster it goes the whiter it goes. Light topic

The kit consists of: a white card template, correx disc, solar cell,

solar motor, motor bracket, small rainbow disc, wire connector +
