Ever wondered how Astronomers find out the chemical compositions of things that mankind has never reached? They use  large Telescopes connected to Spectroscopes.

You can make this simple Spectroscope (designed by Arvind Paranjpye) and yourself use it  to look at the Spectra of various light sources and even the Fraunhofer lines in Sunlight (reflected for safety).
