From the exstensive reserch I did after seeing your posts, I found that the diamond glitter is also called diamond dust. BUT from all the posts I found on this, everyone says the same thing, Does NOT work like the picture shows. That really sucks! Wonder if pinterest knows this? So Sorry everyone!!! I was looking forward to doing this as well! Lesson learned!! I will stick to cooking!!
1Cut a glow stick and shake the contents into a jar
2Add diamond glitter
3Seal the top and Shake hard! Watch their faces glow as well!
