What are rainbows made of? Kids can learn about them with this Light Crystal Prism. When they hold the prism up to sunlight, they'll discover how white light gets refracted into the whole spectrum of separate colors. They can also create their own kaleidoscope using colorful cardboard cutouts and the provided instructions. Made of hard clear plastic, the 4.5-inch prism comes with a hexagonal display stand. In addition, a package insert describes the science of light refraction and reflection in language that's easy to understand. --Joan DeClaire

Bought this for a school science project, ended up being too small. 100% my bad as I didn't look up the measurements!!

This is a high-quality prism and stand that makes it easy to teach others, especially children, about the wavelengths of visible light. It provides entertainment and a colorful outcome. The stand is nice for storage or placing in a window.

I was very disappointed. It was acrylic. not crystal.

Very disappointed. The "Crystal" prism was plastic, and as much as I tried, I did NOT get a single color of a rainbow. The "instructions" are not worthy of being called "instructions" either. The prism is tiny, and the kaleidoscope is a joke. This is my first review, I wrote it for this reason. Unfortunately, I should have read reviews before purchasing; I hope you see this!

I bought 4 for the grandkids, remembering how much I liked a (glass) prism when I was a little guy. But these see plastic and lack the brilliant clarity and sharp focus of glass... so quite disappointed. That said these will work to make a small rainbow. Children will have a bit of a learning curve figuring out how to do that but I think that is ok, and they'll come back to it every now and then over time.Tips: Being plastic out will easily smudge and that will prevent it from making good rainbows. Gently clean w detergent or glass cleaner and very carefully dry without scratching. Second, direct sunlight it's best, and seems brightest from about 11 am to 1 pm, though earlier/later will work. Third, on it's little pedestal, set it on a window sill in the sun and you should see a little rainbow, maybe w with a slight turn now and then. Oh, the "rainbow" it's on the surface of the floor, wall, whatever it shines on, NOT IN THE AIR.

Some time ago, i put a little lead crystal in my mother's window. She loved the rainbows it threw all around her kitchen whilst she washed dishes, etc. She didn't know that's where the rainbows were coming from. When i told her that was the cause, she wanted to learn more. I found this item & gave it to her as a gift. She loves playing with it and using the internet to learn more about prisms and rainbows. Did i mention that she's a Pensioner? Educational & entertaining at any age.

Overall I am satisfied with this prism. I don't use it very often since it just sits on a shelf in my office. It works okay at splitting light but isn't a high end optical device by any means. The plastic base is rather cheaply made as well. Overall for $10 It's a good deal. I wouldn't pay much more than that for it though.

My 3 year old daughter wanted a "rainbow" for Christmas. I thought this would be a nice way to give her one - and teach a little science lesson at the same time. I liked that it was acrylic, which makes it much safer and more durable for a young child. Unfortunately, it barely works, which just makes it frustrating for a young child. If I shine a very bright light on it, in an otherwise dark room, and get the angle JUST right, I can see a tiny, dim rainbow. That's it. I'm keeping it b/c it was inexpensive and not really worth sending back, but it was a bit disappointing.

I'm not sure what the expectation level is of those considering purchasing this prism, but I recall being handed these during science class when I was in elementary school and thinking that they were the coolest thing ever! My daughter, who is still young enough to believe that there is a pot of gold at the end of the rainbow, recently watched an episode of the Magic School Bus which dealt with light refraction and, this summer, saw her first atmospheric rainbow following a rainstorm. So I decided to get her one of these for Christmas. She thinks it's as cool as I did when I was a child. On a sunny day, we sit this in her bedroom window to catch sunlight and cast rainbows in her room (she's just yelled downstairs to tell me that there's one in her room right now!).This prism works just as the ones we used in elementary school, and on the Magic School Bus worked; I suppose because the sun and prisms haven't changed much in these few years! It does not spray the room full of rainbows, but what happens with it is the same, amazing, beautiful, incredible thing that happened when I was a kid, and when Isaac Newton first used this tool to break apart sunlight to reveal every color known to man. That happens to be enough to impress me and my daughter.Footnote: you will not get a full color spectrum with lamplight or fire because all light sources do not contain the full spectrum of light present in the sun. Doesn't make it any less fascinating to look at other light sources through the prism however. The prism just helps you to learn what colors are present in light from different sources.Have fun!***Update: 7/31/2012: My daughter still has this. It still occupies prominent space on her desk. The acrylic surface has held up well through years of play and being knocked into--still shiny and still works!
