I've tried a couple experiments using goo kits where I added metallic/holographic powder to the wax, and it was quite fine powder, and it was exciting for the first few cycles, but then the powder all settled to the bottom of the wax and would not flow with the goo, I also had a very small amount leech into the liquid.
I've seen a couple metallic goo kits on here and I'm wondering if I can find some guidance. How did you get the metallic look to stick in the goo? What did you use to get this effect?
This is a video of what mine looked like at first:
