Abstract

Short-wavelength laser pointers are readily available, dangerous and very affordable. Using 635nm, 532nm and 405nm laser pointers, we examine the fluorescence spectra of various color Play-Doh samples. The spectra are analyzed using a simple spectrometer made of a web-cam and a section of DVD. We present the spectrometer, and the laser induced fluorescence of the Play-Doh as an activity that helps students understand color, spectra, laser spectroscopy, and the energy of light.
