After the OPI shatter craze, nail polish gets even crazier with magnetic nail lacquers from nails inc.!

Each bottle comes with a magnetic cap that creates instant patterns when held over the nail due to the metallic particles in the lacquer. See it in action here.

Available in Trafalgar Square (silver/ chrome), Houses of Parliament (deep purple) and Big Ben (gold) from Sephora US and nails inc. London. A perfect marriage of physics and beauty. :)
