With a plain old CD
With a plain old CD and a light bulb, we can create a range of eye-popping colors and even have before our eyes the entire spectrum of the rainbow. We can use an old record, you are not required to be unrecorded.
If it's a CD, but will have to "shave" the metallized part using the tape. If we use a DVD, you have to separate the two plastic layers that form it.
An experience very easy and incredibly fun to show in your science classes. The highest note is guaranteed ;-)
To observe this phenomenon perfectly, it is necessary to be almost in complete darkness. It can be performed in full daylight but it is not so spectacular.
We can find the explanation for this phenomenon in "Diffraction produced by a crack." Diffraction can be seen when a wave passes through a groove whose dimensions are comparable to the wavelength. Wave, to pass through the slot (in this case would microperforations having the CD or DVD), opens and instead of following the direction of the beam incident many rays fanning form.
A simple search of this phenomenon in the network, we will explain as complicated as we want.
