What a special prism. This quality, acrylic prism comes in a pleasingly large size, measuring 11.4 centimetres (or 4.5 inches) long. Best of all, it allows you to bring a rainbow indoors. Correctly positioned, this unique prism bends (refracts) an ordinary beam of light and disperses a colourful spectrum onto a wall or other surface.

Although the Light Crystal is perfectly clear, it looks like its internal walls are lined with mirrors as light is reflected by the angles within. This pretty prism comes with a base and tear-out coloured designs... look through the top of the bevelled edge for a cool, kaleidoscopic pattern effect.

Age: 8+

How does it work

Since the first moment a rainbow appeared in the sky people have been fascinated with prismatic effects. Light travels more slowly through the prism than through the air. When a beam of light enters the prism at an angle, this slowing, bends (or refracts) the light. How much it bends depends on the wavelength. Since white-light is made up of all the colours of the rainbow - each with a different wavelength - the colours are dispersed into a spectrum with the longest wavelength, red, bent the least and the shortest wavelength, indigo, bent the most.
