I’m looking for a yoyo that will glow under UV light. I’d love for it to be POM/Delrin, as I love the material. Wondering if anyone knows what colors of POM will be UV reactive? If you have pictures/videos of the effect for any color of POM, please share them!

I’ve seen a video of a pink POM yoyo glowing really well, and I saw someone comment here that red POM glows well, but I haven’t seen it. I have a green POM yoyo, but it does not glow under UV light.

My green Desert Island Yo (DIY), with a string that glows really well:
