Naff Movie into 'DVD Spectra'

Step 6 Fitting it together

Fit the DVD into the case, shiny side up. Fit the wedge in place, slit closest to the front of the case. If you want to be able to break the DVD Spectra apart for storage, fix it using a little blue tack. If you want a permanent construction then a little stickytape to fix the wedge sides in place, and a little along the top edges will make a stable wedge shaped spectrometer.

If you are making this to be permanently constructed, you may like to use thick tape to block any light from entering the case, except via the slit itself.
