How does it work?

To create your rainbow spectrum, find a light-coloured wall with a nearby light source (like a window or lamp) and hold the prism up to the light. You may have to move it around a little to see the rainbow. 

When white, or ordinary light, moves from air to the glass prism, it is bent (or refracted) at different angles depending on wavelength. Upon leaving the glass prism, the wavelengths are bent again at different angles allowing the spectrum to be displayed. Violet light is spread one way, and the red a different way, with the other colours arranged in between. 

Natural rainbows occur because rain acts just like tiny prisms bending and splitting light.


  • Light and colour properties
  • Light is composed of different wavelengths and colours
  • Spectrum
  • How rainbows are formed
  • How light travels in different mediums.


The intensity of the spectrum produced depends on a number of factors, including the source of the light, room brightness, wall colour, and angle of prism. A bright, vivid spectrum can only be produced under very specific conditions, and with a lot of patience. In the event of breakage, or splintering, dispose of immediately.

WARNING: CHOKING HAZARD Small Parts. Not for children under 3 years.
