“Black hole” magnetic technique

Not sure if it’s a “new technique” but I figured out a way to get that “black hole” effect I see a lot with gel polish.

Base: ORLY nail defense
2 coats BKL beautiful in my darkness
Top: BKL I’m fast, very fast

Placed neodymium bar across tip of nail, skinny-side up, and moved up and down slightly, to create a curve of pigment at edge of nail. (Photo in comments).
