How to make a light splitter using CDs

To create a CD spectroscope, start by cutting a narrow slit in a cardboard box to control light entry. Position the box so that light hits the shiny side of a CD at a shallow angle, causing diffraction. Often used to look at stars or gemstones, the resultant spectrum enables the viewer to determine the makeup of the. With a simple tool called a spectroscope, astronomers can break light apart to study stars, planets, and galaxies—even from millions of light-years away!
