Color Wheel

(The wheel can be made with a paper plate, and the snap can be replaced by a paper fastener.)

Polarizing material and Karo corn syrup: When polarized white light passes through a sugar solution, each color’s direction of polarization is changed by a different amount. The colors change as the depth of the solution changes or as the polarizing filter is rotated.

All organically produced glucose rotates the direction of polarization of light clockwise. This sugar is called d-glucose. Another sugar, called l-glucose, rotates the direction of polarization counterclockwise. It can only be made by inorganic chemical synthesis. Both d-glucose and l-glucose have the same chemical formula: C6H12O6. However, the atoms in each of these isomers are arranged in a different pattern. The left-handed sugar (l-glucose) tastes just as sweet as the right-handed one (d-glucose), but your body can’t use it as an energy source. That’s how left-handed sugars can produce sweetness without calories.

All the proteins in your body and in all organisms on Earth are made from amino acids that rotate the direction of polarization of light counterclockwise. On the other hand, laboratory-­synthesized amino acids, and amino acids found on meteorites, are made up of equal numbers of amino acids that rotate light to the right and amino acids that rotate light to the left. No one knows why this is so. From https://www.exploratorium.edu/snacks/
