These premium quality diffraction ‘rainbow’ glasses are great for birthday parties, electro-magnetic spectrum investigations or to spice up any science lesson or diy science workshop. Take them to a firework display and you will never watch a display without them!
The diffraction grating in these cool glasses creates the rainbow spectrum of colours. Look at any artificial light source of light such as a bulb, torch, candle, led or street lamp (preferably when the ambient light is low) and prepare to smile at the effect.
