Sciencent Set of 3 Equilateral Acrylic Prisms 1" 2" 4"

Product worked perfectly.

I would highly recommend these for children under seven, once children are old enough to use glass you’re much better off with crystal optics as they are much more capable of bending light into it’s spectral properties. They do work but the spectrum spread is small and tight and requires some distance to fan out. This is not due to a product defect but to the lighter density of plastic over glass or leaded crystal. Although they can chip and scratch because they are plastic I am glad I purchased them for my two-year-old and four-year-old as there were a couple of incidents of the prisms been dropped. On a sidenote you should understand that prisms of any kind don’t always work with LED lights. Most LED lights operating in a narrow light spectrum unlike incandescent lights and aren’t always capable of generating complete rainbows.

Fun. Good price.

Some of the prisms had flaws.

I remembered having these as a kid, so I bought these for my kids. they're a little on the cheap side (as I expected), but they work as described and entertain the kids as I had hoped.

Bought these because my 4 yr old said the prisms were his favorite thing to use at school. After a couple minutes he put these down and said they didn't work. I tried them and admit they don't work well either. Going to find out what kind of prisms they have at his school because these are a dud.

My autistic son for some reason became fascinated with prisms so we bought these on impulse for him and he wouldn't put them down for weeks. Even asked for them the second he got off the bus for the first week.

Daughters are into rainbows so I got this to let them make their own. They work well except being plastic they got scratched almost instantly. They still work though and I guess scratches are better than broken glass.

They work and they're nearly flawless. I'm learning myself from the counter-intuitive things!

I bought this for my son's grade 4 science module (during the Covid 19 pandemic). The acrylic material didn't produce the rainbow spectrum with most light sources we had around the house ... and when we did find a light that worked the spectrum fan was extremely thin. For the cost, I was expecting a bit more. Pass this one up and spend the extra few $ for the optical glass version.

They are ok. Able to show the kids small rainbows in sunlight if you hold it just right. They are plastic and scuff easily. Mine came already scratched up and I had a hard time getting them working.

They work great and being acrylic are easy to clean and safe to bring into a kindergarten classroom! Thoroughly enjoyed by all!

Verrue good so good
