You can make one using a disposable plastic cup and one of those protective transparent discs you find when you buy a spindle. 1. Take a plastic cup and put it upside-down. Use the knife to cut a straight line in the bottom of the cup. Then use scissors to make the line into a slit of about 1mm (3/8 inch) wide. 2. Align the outside of a transparent CD or DVD with the rim of the cup and align the slit horizontally, then tape the two together with some cello tape. 3. Done! Hold the cup near a light source and move it around a bit to see the spectrum. Improve: remove the tape and colour the inside and bottom of the cup black with a marker pen, then tape it back together. This method requires no dangerous cutting into CD's, using razors or hard-to-get poster-tubes. Click my username for pictures! It’s a fun project, but I think you’ve made it a little complicated.
