🔥 Rob's Super Fun Store Fireworks Diffraction Glasses - 50 Starburst Effect Glasses + 1 Rainbow Hearts Effect Glasses - Optimize Your Search! Review

It was a great price. We used them to teach our fifth and sixth graders at church. The diffraction worked well to distort her vision, but for our purpose I'd like to do it even more. However, they work as advertised, so I have no complaints. One nice thing about these choices is that they're fun and bright, with a glossy finish (as pictured) rather than monochromatic.

Bought these as a birthday present for my preschool classmates. The kids had a blast with it and it was a great alternative to candy. You get a lot of product for the price but as a science teacher with a lot of experience with spectral glasses they weren't the best in terms of spectral diffraction. The rainbows worked reasonably well, seem durable and should last a while, but we didn't see any diffraction in the heart diffraction glasses.

These diffraction glasses are made from thick paper material and printed with a colorful vibrant design. This year I ordered them to put in my daughters gift bags and they were a hit with her classmates in 2nd and 3rd grade! They are suitable for both children and adults. I would recommend them because they are so much fun and I can't wait to use the extra pairs we have for the 4th of July fireworks! If somehow the two extra pairs we have go away sooner I wouldn't hesitate to order another…
