![]() Because the CD’s surface is mirrored, the light is reflected to your eye. These tracks are evenly spaced and diffract light (separating the colors). Compare what you see!Ī CD is a mirrored surface with spiral tracks or pits. Now try your spectroscope with other light sources like fluorescent light, neon light and candle light. Point the top slit up at the sky (NOT directly at the sun). Start by taking your spectroscope outside. Insert the CD into your 45° angled slit with the shiny side facing up. Burn discs, erase them and everything in between. Tape the circle to the top of your spectroscope.ħ. CDRoller 11.60.10 Powerful, easy-to-use and low cost toolset for CD/DVD/BD/HDD/Flash data recovery. Cut a straight slit right across the center of your cardboard circle.Ħ. Trace one end of your paper towel roll onto your small scrap of cardboard or cardstock. Directly across from the slit, make a small peephole or viewing hole using your craft knife (another step for an adult).Ĥ. Use a craft knife (an adult should do this) to cut a thin slit at a 45° angle toward the bottom of the cardboard tube.ģ. (This step isn’t necessary, but it’s hard for us to pass up an opportunity to paint something!)Ģ. If you’ll be painting your paper towel roll, you’ll want to do that first and let it dry.
