Angelique Kerber may have become world No. 1 and won two Grand Slams in 2016, but a new challenge awaited her in the new year: bottle flipping.

She embraced the latest trend sweeping YouTube and social media outlets where you literally just flip a full bottle and try to get it to land perfectly upright. Kerber, of course, is actually good at it, nailing it on her first attempt.

Kerber will start off the season in Brisbane by facing wildcard Ashleigh Barty.
