The Bottle Cap Challenge is the latest viral video craze and involves a roundhouse kick unscrewing a bottle cap with your foot without knocking the bottle over.
It apparently began with mixed martial artists trying and successfully doing it and now a few celebrities have uploaded videos of them doing it.
Jason Statham, who is a martial artist, has done it as has John Mayer, who is not a martial artist.
The videos are usually in slow motion to enhance the effect of the cap unscrewing and flying off.
This compilation shows some successful BCC participants but you may notice that some of them show someone holding the bottle and others don't show the bottom of the bottle so someone could be holding it.
