This was a project I did for my wedding. Created nearly 100 of these "throwies" and set them throughout the woods in the area of our wedding. Overall the project took longer than I am willing to admit but the effect was worth it.

Enjoy this project?

So the GITD paint makes the light dim relatively slowly when the UV LED goes off? How did it look? I'd love to see a video showing the effect.
