I was excited to see this experi because I had in my mind to try this. The difference was I was thinking about using a syringe. I imagine the syringe would give it more pressure in the release and possibly have more of the spread effect.
Yes a syringe is a good idea. I was also thinking of mixing up the mica and alcohol in a small, plastic squirt bottle and squirting it in. Maybe in a future video 😉
