It's a really cool effect, but never in a million years did I think you could actually drink something like this. Turns out I was wrong. Worse, it looks like mixing shimmer powder into a drink might be a million dollar idea. I present to you..."Viniq Shimmery Liquor"!
And here's a far more entertaining look at the product. Lots of F-bombs, so it's NSFW. Heh.
While Viniq is obviously a novelty, infusing consumable liquids with food safe mica powder seems like a bang-up idea for Halloween parties and LARP potions. Unfortunately, in pure water it settles out of suspension pretty quickly. I suspect you would need to increase the specific gravity of the liquid with glycerin or sugar syrup to keep the particles in motion.
