I saw a youtube video where some photographers were using a prism to create faux light bleeds in their pictures so I decided to purchase one for the same reason. I tested it out yesterday (I definitely need some practice with it, still) and it actually created some cool effects with my subject so I'm excited to mess around with it some more and see what else I can do with it!

I frequently conduct optical experiments and simply enjoy playing with light. I received these prisms as a birthday gift this year, and I'm impressed with their high-quality glass, free from any visible defects. The edges are also quite sharp, making them excellent prisms for the price.

I absolutely adore this product! The packaging is so charming. I purchased this prism for my students, and they were thrilled by the rainbows it produced. It served our purposes well, allowing us to observe all the colors when exposed to sunlight. However, please note that these prisms are made of glass and can break if mishandled by children. Exercise caution.

We bought this for our child's 5th-grade science class. Due to budget constraints, the classroom didn't have a prism to demonstrate the color spectrum visually. This prism arrived on time, just before the end of the chapter, and it gave all the kids the opportunity to witness an indoor rainbow. We believe that hands-on experiences like this are crucial for effective learning. It worked perfectly.

I purchased this as a gift for my nephew and decided to test it before giving it to him. With some practice, I was able to produce decent results. I used a small flashlight and adjusted the angle and distance until I had beautiful bands of color. The prism is heavy and of high quality. I'm giving it 4 stars because a perfect prism would have sharper edges, but I'm satisfied with my purchase.

The item was very well packaged and arrived earlier than expected. The sturdy box it came in is of great quality. The prism itself is of excellent quality and produced beautiful rainbows as expected. It's definitely a valuable addition to our science teaching materials.

I used this for a science experiment with my daughter, and while it worked, it doesn't meet what I would consider optical quality. Given the price, I'm not particularly surprised. It was sufficient for refracting sunlight in a simple demonstration, but not much more.

When I looked out the window through the prism, I was able to see multiple rainbows inside it, each spanning the entire length of the prism, with several rainbows stacked beneath one another.

Ideal for homeschooling, these charming glass prisms serve as the foundation for numerous science activities. They are the perfect size for classroom or home-based explorations.

I recently added this prism to my camera gear, and it's been fun experimenting with it through the lens.

I bought this hoping it would help realign the gyroscope on my flux capacitor. It was just okay for that, but it did create awesome rainbows for my 6-year-old!

This prism has a substantial feel to it and works exceptionally well. It came in a beautifully packaged box with a styrofoam insert wrapped in a soft cloth material, which can also be used for safe storage. It would make a lovely gift box as well.

They're a bit smaller than I expected, but they work wonderfully for my rainbow-loving kids.

The packaging is aesthetically pleasing, refracts light to create a rainbow effect, and has sandblasted sides to prevent fingerprints on the prism. It's reasonably priced and makes for a great gift.

Works perfectly, producing a rainbow in the sunshine, unlike the cheap plastic one I bought from another source.

Bought this to assist with a science lesson for my kids while we're at home during the coronavirus pandemic. Initially, I couldn't get it to work, but eventually, I discovered that the key was to aim the light at the edge of the prism. Sure enough, we managed to create some pretty good rainbows.

I had hoped for a more spectacular rainbow display! Nevertheless, it is well-made and still emits some light during a specific time of day. I personally prefer teardrop prisms.

I can't really blame the manufacturer for the chips; it was perfect when it arrived. I accidentally dropped it twice, which was my fault. It did withstand the falls reasonably well, but it did chip in a couple of spots. However, considering it's made of glass, this isn't surprising.

I purchased this for my photography, and I absolutely love it!

I purchased one of these for my child, and he absolutely loves it. He has a blast looking through it. When you peer through the end pieces, it creates a kaleidoscope effect, and when looking through the long part, it produces a rainbow outline effect. It's quite entertaining, and anyone observing the viewer can't help but find it amusing. Thank you for such an enjoyable product.

This item is great but somewhat fragile. It chipped at the top when it fell over after being bumped.

I tutor a 14-year-old boy in eighth grade, and his science class is struggling. I purchased these prisms to demonstrate sunlight refraction. With the Sun behind me, I placed the prism over my shoulder and projected the spectral display onto the shadow in front of me. It was beautiful - violet, blue, green, yellow, and red.

I appreciated the size of this piece. It is suitable for both physics experiments and photography. I look forward to working with it.

It works exceptionally well to make a small room more visually appealing, especially when used with a 50mm lens. The packaging is premium, and the glass is quite durable.

It works with sunlight to create a rainbow. However, I couldn't get it to work with LED flashlights. This might be because LED flashlights have a different color spectrum.
