Review: It works for rainbow chocolate! - I bought this purely for my elementary science class so we could make rainbow chocolate. (We've been discussing light, so this seemed like a great last-day-of-science treat.) It worked really well! I just melted the flat side of the Dove chocolates on a frying pan and then pressed the chocolates down firmly onto the sheet. It shows up best on dark chocolate, but you can see it on other kinds as well. (Sunlight shows off the rainbows best.) You can wash and reuse the film but you have to dry it (or you might get water residue that will mess up future chocolate rainbows). Also, be very careful not to crinkle it. The sheet comes in a cardboard tube, which I thought was great until someone threw it away, thinking it was trash. Big sad. If you buy it, put a label on the tube so that doesn't happen to you! The kids loved just looking through the sheet at each other and the windows, etc. Definitely a good investment!
Review: Excellent value and perfect for 3d printer first layer "rainbow" effect - I ordered this specifically for utilizing it on my 3d printer bed in order to give the first layer of my 3d prints a "rainbow" effect. I appreciate that desertcart had it at such a great value. The package arrived at a moderate pace but was packaged safely in bubble wrap packaging and comes rolled up in 5 individual sheets. Each sheet is long enough to cover 75-80% of my Creality V3 bed. It would require two sheets to fully cover the bed in entirety. In order to determine which side needs to be facing up, you can run a fingernail across the grating, if you can feel a slight ripple, you have the correct side up. If it is completely smooth, it is the non-grated side. You can also determine it by the reflecting light, if you see rainbows, then you are looking at the correct side (up). I applied this to my 3d printer's bed by laying down an initial layer of Elmer's gluestick, then rolled this on top of the glue, then used Frog Tape (slightly better than normal blue painters masking tape) all around the edges. You will want to ensure that there are no bubbles under the diffraction grating otherwise they will appear in the first layer of the print. You can re-use this over and over for quite some time as long as you don't wreck the diffraction grating sheet when removing the print. PLA and PETG stick quite well to the diffraction grating. I do not use any elmers on TOP of the diffraction grating (only under it to hold the sheet down). I really liked the effect this leaves on my 3d prints (see photo). Overall I would recommend this to others looking to do the same.

## Questions & Answers

**Q: Can you please tell me *precisely* what type of plastic these defraction gratings are made of? Not all plastics can be laser cut.**
A: the film is a polyester substrate with an embossed holographic pattern.  the diffraction pattern is not actually cut...it is embossed!

**Q: how do you apply this to a window?  I have a window on the top 1/2 of the main door to my house.  If I apply in strips, will the lines look bad?**
A: Diffraction grating works by having 100's of tiny lines that basically diffract the light into rainbows. These lines are physically etched into the thin plastic. Even finger print smudges effect this. You couldn't glue it on bc the glue would fill in the lines. I'd recommend those sticky "glue dots" in the corners. I don't know if the strips will look bad because I can't see where you are putting it but I doubt it would be that much of an issue. I'd think that something like this would have to be redone every few years b/c it can't really be cleaned. You'd also want to make sure that it wasn't touched often or... you could set everything up and screw a piece of plexi over top  that's cleanable and wouldn't have to be worried about how delicate it is. That would protect the diffraction film. Also, as a side note, there has to be direct light in order for this to cast rainbows.

**Q: I want to put this on the outside or inside of a glass elevator. What should I use to attach it to the Glass so that the other side also looks good.**
A: There is a video where EvanandKatelyn use UV boat resin to mount it to wood. It looked fairly good. If you can remove the glass to attach it, it might work.

**Q: I want to make my own fireworks glasses.  Is this what I would want as the lenses (the double axis)?**
A: Yes, I would recommend you that. Sheet 13500 lines/inch reflects in 8 directions, so it's really good for firework glasses.
