This one is useful for taking to impress your kid's classmates in a school show, but not bright or dispersive enough for use when you have the better versions available.
SUGGESTIONS:

EQUIPMENT: Mounted 100 watt clear straight filament bulb with "light shield," slit, 10 cm focal length convex lens, and cheap prism.
