Optical Glass Triangular Prism, 2 Pack 1.97 Inch Crystal Rainbow Maker for Photography Science Experiments Physics Teaching Light Spectrum11

My 4th grader had a big school project and the topic was rainbows. So this was great. She was happy with it. It even came in cute packaging!

Got what I expected. Nothing damaged. Nice box with two nice prisms inside.

It does what it says and is great for kids to learn about light!

I've been using prisms since I was a young child; I'm now a teacher and was excited to use these with my students.They do not work. Where there is supposed to be a rainbow spectrum, it's a spot of plain white light -- no matter how I turn it, no matter what kind of light source I use, no matter the angle, how bright, etc. I've never in my life seen a prism that produced plain white light instead of a spectrum.

Overall good value for price but one of them did come with a small chip in the corner. Not enough to make me return it because it's still in working condition but a little annoying considering the amount of packaging.

These glass prisms came in a bubble mailer. Upon opening, I found that the boxes were crushed and one of the items was chipped in several places. Other than the condition of the product from mailing it was as expected.

The media could not be loaded. Nice packaging, bends light to casts a rainbow, sand blasted sides that help to keep fingerprints off the prism. Good price and very giftable.

Received exactly as pictured. One is wrapped and not broken, the other is NOT wrapped and has a massive crack as if it were dropped on it's corner. It's clear this damage happened before shipping and the seller figured it would be fine for customers to receive this.
