You might not think robots have anything to do with makeup, but NARS Cosmetics is enlisting a robot to help you win a massive stash of beauty products. Tomorrow, to launch its new collaboration with designer Christopher Kane, the beauty company has filled a mysterious onyx orb/egg with its entire collection, along with a Kane handbag. Starting at 1 p.m. EST, tweets hashtagged with #NARSChristopherKaneUS (U.K. residents can use #NARSChristopherKaneUK at 11 a.m. GMT) will summon a robot arm to strike the orb/egg over and over until it breaks. The winning tweet will win the orb’s contents. Note that robots of the spam variety, however, cannot help people win. Watch the video below to learn more and catch the whole thing on the livestream here. Consider it the Twitter version of a giant makeup-filled piñata.
