 Acrylic RainbowsAug 30, 2010
A prism made of plastic. I thought that word "crystal" meant glass and was surprised to find a toy made of plastic. It's a bit "milky" and there are discernible imperfections, but to illustrate the basic properties of light, specifically that bending light changes its frequencies, this product suffices.
 Not what I remember from school.Jun 16, 2010
As others have said, it was not the vibrant and bright rainbows I remember from school. I remember getting SOME color separation out of a bright flashlight. But as others have suggested, that was probably because those prisms were made from something other than acrylic.
This one, I could not even get a separation of colors with sunlight through a window. Much less using a flashlight or any other artificial light source. Maybe a photographers lamp or bright worklamp would get something.
All that said, there is a way to get a pretty dramatic set of bands. What you want is for there to be very bright direct sun near an open doorway or a shadowed area, preferably about mid-day. You want the sun to shine into the prism and refract such that the resulting rainbow forms in the shaded area (I did mine at the door to my garage). I managed to get a band of color that was about 4-5 inches wide and about 12 inches long on the floor of my garage doing that.
 Wish it was made out of glassMay 17, 2010
After looking for a glass prism, I just couldn't find it, so I ordered this one that is made of clear plastic.
It probably doesn't work as well as a glass one, and it's a little bit tricky to get it to produce rainbows.
But eventually it does, you just have to make sure that is very, very clean, wiping off any fingerprints with a microfiber cloth -the ones used to clean eyeglasses.
Great educational value, I'd say a classic. But again, I wish it was made out of glass!

Well, yes, it looks good on display sitting on your shelf. But as for creating a striking prism rainbow i remember creating in 5th grade (decades ago) with a real crystal prism - it simply does not deliver at all. A standard household flashlight with new batteries should be enough to do the job but it doesnt. You can barely see colors on the outside fringes of the beam and you will need to hunt for them by rotating the prism. :(
Sun BeamJan 28, 2010
The Prism worked as expected. The challenge is to find the optimum sun beam.
