This prism was significantly more expensive that the least expensive but is listed as having a book that goes with it. The book is actually about 2 inches wide and 4 inches long and contains so little that its hard to believe anyone could list it as a "fun and informative guide book".

Pass on this one.

Itsalso not optical grade and edges were a little rough cut. This just a section cut from a long plastic extruded rod. You can get them all over the web from plastic suppliers and cut them yourself if you have a power saw table. I don't. You can (carefully!) melt the cut edges with a torch to polish quickly. Glass works much better, but breaks,this doesn't, and the scratches that happen can even create interesting effects sometimes.

i could not get this to produce the rainbows with office lighting,led-type flashlights. i am going to try regular lilghtbulbs. it works with sunlight. i am not a science teacher so i do not know if a glass (breakable) prism would give me more light sources for the rainbow effects or if it has to have sunlight. They were still fun to watch the refracting angles it would send the light to, but i was trying to produce rainbows at a nighttime class. It es extremely tough and durable and cheap compared to the allglass ones though.

While the description clearly states this product is made out of "high quality optical glass" it is in fact made out of plastic. I paid twice as much for this prism specifically because it was advertised as glass. Bad seller
