rainbow prism

A rainbow prism is a clever little optical device that splits white light into its glorious spectrum of colours, much like nature’s own rainbow but in a neat, geometric form. It’s made usually from glass or acrylic, designed to refract light and separate it into red, orange, yellow, green, blue, indigo, and violet. Perfect for science lovers, photographers, or anyone wanting to add a splash of magic to their day.

In Australia, these can be snagged from specialty science stores or online for anywhere between $10 to $50 AUD, depending on size and quality. They’re great educational tools but don’t expect them to double as sunglasses or anything practical. For buying options, check out Tradingpost or CarShowroom for novelty items.
