I think it is a safe bet that most of us have passed a dirty vehicle with the words 'wash me' written on it. Not exactly what you call 'art'. Russian street artist, Nikita Golubev is creating really cool art on the back of dirty vehicles with a paintbrush and his finger.
If this bartender was pouring 17 tequila shots at once - I would really be impressed. All kidding aside this really is quite a bar trick and potentially many bad decisions to whomever is partaking in the shots. Cheers and bombs away!
