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.

Fantastic tool for dog owners!
Size: 1-pack
This is a great tool to keep your dog active without getting your hands messy! I discovered it launches better when you don't push the ball completely into the holder, but just have it in partially. The ball included is nice and bouncy. The launcher also works with Kong balls.

Endless Fetch Fun—Perfect for My Jack Russell!
Size: 1-pack
This ball launcher has been a total game-changer for fetch time with my Jack Russell! She has tons of energy, and this helps me keep up without wearing out my arm. It works great with most standard tennis balls, so I don’t have to worry about tracking down special ones.

It is good for small yards but not so good for distance.
Size: 1-pack
Getting used to a ball thrower takes practice. This one is no exception. The angle is off for me. If I use it as an extension of my arm it goes straight to the ground, but once I got the hang of it. Balls launch with great height. Distance isn't a feature for this tool.

Get a longer launcher. This only throws 30 ft
Size: 1+3pack
Buy a longer launcher!!! I got what I paid for! A 12.2 inch launcher does not build up enough energy to throw it very far and it is tweaking my elbow. The dog is very disappointed since the ball only goes about 30 feet. I’ll keep it for small dog park use. The balls are hard and my 22 pound Cockapoo can’t get it to squeak.

These are dog tested and approved.
Size: 1-pack
The launcher works very well and will probably last forever unless your dog chews it up while bring it to you to get you to play, but the balls, well, they're not made for labs, that's for sure. That's the bad news. The good news is that worn out or abandon tennis balls fit the launcher just fine. Save your throwing arm. Do your dog(s) a favor. Buy this thing.
