Nars is drumming up a Twitter frenzy with its new digital giveaway campaign for its limited-edition Christopher Kane collaboration. Tune in to the oddly mesmerising glossy orb, via the Nars website or YouTube livestream, which contains the covetable collection.

Each time someone enters the giveaway by using the dedicated hashtag – #NARSChristopherKaneUS – a chisel takes a chip out of the orb. As the Twitter activity translates to more and more cracks in the orb, ultimately there will be one tweet to break the orbs back, and that person will be the winner. Take a look at the competition teaser video above before checking out the livestream.
