Newton proved this in 1704. Try it yourself.\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eWhite light is not a single thing. It is a superposition of all visible wavelengths, from 380nm (violet) to 700nm (red). Newton demonstrated this by splitting white light with a prism in 1666 — and proved it reversible with a spinning colour disc in 1704. When the sectors spin fast enough, your visual system integrates them over time, averaging the colours to produce white. This is additive colour mixing — the same principle used in every screen, TV, and monitor you've ever seen.\u003c\/p\u003e\u003cp\u003eIncludes multiple disc designs: standard ROYGBIV, complementary colour pairs (which produce grey), and blank discs for custom experiments in perception.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIncludes:\u003c\/strong\u003e Motor-driven spinning base · 4 Newton discs · 2 blank discs · Colour pencil set · Additive vs. subtractive colour mixing guide\u003c\/p\u003e\u003cp\u003eAges 7+.
