Super colourful suncatcher crystal

This big glass (not plastic, like some cheap ones) crystal is 12cm long by 2.8cm wide and 1.5cm thick and works like a prism. However, it is coated with a special layer that helps it create all sorts of colours by splitting an incoming light source, so it creates quite a colourful display.

Great for experimentation, or just hang it in a sunny spot. It has a hole at the top and comes with a hanging cord.
