The man who started the bottle cap challenge
The bottle cap challenge is taking social media by storm with loads of celebs giving it a go.
But where did it start? Taekwondo ace Farabi Davletchin is the man believed to have, ahem, kickstarted the bottle cap challenge trend.
Action star Jason Statham then got involved, posting a slow-mo video of him taking the challenge.
Since then everyone's been trying it.
