Review title: Doesn't work
Product review: Strange as this will sound, this "prism" doesn't seem to work. I've tried it with a variety of light sources (flashlights, lamps, etc.) and can't get it to show colors. The packaging assures me that it does what prisms do (splits white light into a spectrum), but this just seems like a triangle-shaped piece of plastic. I've held it up to the light from literally every possible angle and...nothing. Not at all the fun toy I expected.
