The Newton's Colour Disc contains seven rainbow-colored segments: violet, indigo, blue, green, yellow, orange, and red, in that specific order. When rotated, the colors eventually fade into white, proving Isaac Newton's theory that white light is composed of the seven colors of the rainbow. This disc serves as a visual demonstration of this scientific concept. 

It is used to demonstrate color mixing and the spectrum of colors. By rotating the disc, it creates a range of colors formed by the combination of its colored segments. This product is commonly used in educational settings, physics demonstrations, and experiments related to optics and light where the color spectrum is significant.

This apparatus utilizes a drive system that involves a rotating belt to generate movement in the disc. Keeping a spare belt on hand is beneficial in situations where the original belt experiences wear or damage. This enables the swift replacement of a vital component, guaranteeing that the Newton's Colour Disc stays operational.

Smells great and works great too!
Style: Spray (2 Oz)
Great sunscreen and smells fantastic. Not sticky or greasy feeling, but the bottle seems a bit small for the price. Took it to the beach for the 4th of July week and it was the first time I didn't come back with my "base burn". So it really works well. Great size for carry-on travel, but again a bit pricey for the amount you get.

Amazing smell amazing feel
Style: Spray (6 Oz)
Product arrived without damage! My absolute favorite sunscreen! If it’s ever on sale, I highly recommend trying as it’s not the most affordable. Never makes me feel greasy and is so lightweight! I never have breakouts with this either. Smell just adds to my obsession more too
