The nail polish girlies have found a new favorite tool for magnetic cat eye nail polish — the Apple Watch charger. Reddit user peninkling shared photos of a stunning shimmery blue-to-black gradient achieved by pressing a finger to the charger, applying magnetic polish, and waiting about one minute for the effect to lock in.

Mooncat polishes Getting Even and Bloodbender recreate the look. Instagram user Sarah Kendall also demonstrated the method. Magnetic polish contains ferromagnetic particles that respond to localized fields, creating effects like cat eyes, velveteen textures, or shapes.

Redditor Glittering-Time-2274 notes MagSafe-compatible accessories — magnetic Pop Sockets, mounts, or wallets — work similarly. The trend highlights inventive repurposing of everyday tech for beauty routines.
