Buy 5-3/4" LONG GLASS TANK PRISM. 1-1/2" ON EACH LEG.

Customer Ratings:

As a homeschooling mom, I ordered this prism for a science unit on light later this year. However, it was a huge hit in my house from the moment I opened it! Both kids had a blast making rainbows and seeing the optical illusions from this. I only subtracted a point from durability because it is glass after all, but it is extremely heavy duty.

It came very well wrapped in bubble wrap, and was shipped extremely quickly. Despite the warnings about chips, I haven't noticed any. The company also sent me a catalog chock full of stuff I never knew I could buy ;) The product descriptions often had me in stitches.

Absolutely recommend this wonderful company.

Prisms are amazing in that they educate us on the physics of light behavior as they relate to various mediums. My son is 4, and he is enjoying the brilliant light behavior as he looks through this prism. Later, we will shine a makeshift light box through the prism and cast the refracted light upon paper in a dark room.

Remind your child that this prism is glass, and it must be handled with care. I recommend making a point to the child that it is best not to run around with it on concrete. Keep it safe above a soft surface in case it falls.

I am very happy with the product. It is hefty and heavy duty. Definitely not cheap.

Best Deals for 5-3/4" LONG GLASS TANK PRISM. 1-1/2" ON EACH LEG.

I bought this for my 11 year-old grandson's birthday. I Was tired of buying toys that lasted or were interesting for only hours. My grandson's are fascinated with all things WWII right now and this boy, in particular, likes to know how things work. His prism came with a small chip but no scratches. The chip actually makes it seem more authentic and he is excited to think it just might have been in a real army tank 65 years ago! It is a lot of fun to play with but remember, it is glass and it would break if it was dropped. Very heavy, very cool, no batteries to replace. It was delivered quickly and was well packaged. Not exactly a toy but lots of fun.

Honest reviews on 5-3/4" LONG GLASS TANK PRISM. 1-1/2" ON EACH LEG.

This is a large and solid piece of glass and does a beautiful job splitting the light. Mine was however nowhere as perfect as mentioned in other review. Light scratches and a big chip. Good for using it to split the light, not good for a showpiece/decoration however.
