Thanks.** A: No...it appears to be made of an acrylic-type substance. I would have liked it more if it had been glass. **Q: How many are there?** A: I bought this product 3 years ago, the price is per one item; the size (2.75in X 2.75in X 2.75in) refers to the dimensions of the box that contains the prism. A lot of fun for sure! **Q: if i put it above the light bulb in my lamp shade would it create the illusion of a rainbow beam?** A: I believe it should be possible to get the rainbow effect with a lamp but the trick is to get it at the right angle to get the desired effect. **Q: Is this crystal really not crystal?** A: If you think about it, the "crystal" that most people think of when they think of prisms is cut glass, which is not actually a crystal, but is amorphous. Acrylic, which this prism is made of, also is amorphous and non crystalline. A true crystal is anisotropic and would be less optimal than either glass or acrylic for making rainbows. So the answer is, "No, it isn't crystal, but it works fine for separating white light into its constitutive colors." ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works *by A***R on June 18, 2025* I was looking for an acrylic prism to teach my son about light and rainbows. This is simple and does the job with natural sunlight. ### ⭐⭐⭐⭐⭐ Great For Teaching Science! *by H***A on March 22, 2013* My kids have always been fascinated by rainbows and enjoy them even more knowing they can make them themselves. This is a simple, lightweight prism they can use for doing just that. It's fairly clear in order to make some decent rainbows. It also comes with a simple instruction booklet with images to make some neat kaleidoscopic images. It works great as a prop for describing the properties of light in our homeschool. ### ⭐⭐⭐⭐⭐ Perfect for dramatic color spectrums *by D***S on March 17, 2013* I bought this prism for my grandson's 2nd birthday because he always marvels at the rainbows produced by the beveled glass top on our dining room buffet when the sun strikes it just right. For the most dramatic spectrums from this prism, I use sunlight streaming through a window and project the spectrum on the floor or the opposing wall. Indoors works best when the spectrum is projected onto a wall in the shadows. Outdoors, the spectrum is attenuated by the brilliant sunlight. You have to exercise care (as with all prisms) to orient the prism at just the right angle to disperse the colors for maximum effect. If you have the incorrect orientation, you may just get a reflection from the prism with no colors, or a white shape with color fringes at the edges. When you achieve the correct orientation, however, the spectrum is dramatic and brilliant. My grandson is mesmerized by it. Highly recommended to stimulate the scientific curiosity of children. ## Frequently Bought Together - Constructive Playthings Light Crystal Prism, Rainbow Maker for Kids, Science Class, Ages 8+ - Light Makes a Rainbow (Science Readers: Content and Literacy) - Curious George Discovers the Rainbow --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/284321-constructive-playthings-light-crystal-prism-rainbow-maker-for-kids-science](https://www.desertcart.co.uk/products/284321-constructive-playthings-light-crystal-prism-rainbow-maker-for-kids-science) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-16*
