Also known as: ボトルキャップチャレンジ
A Memetic internet challenge where a person attempts to unscrew or uncap a Bottle using a Roundhouse Kick without toppling the bottle over.
The origin of the challenge is unclear, but the spread started when Farabi Davletchin, a Kazakh Taekwondo champion, posted a video on Instagram successfully using the roundhouse kick to uncap a bottle and then challenged celebrities to do the same (several celebrities, martial artists, and ordinary folk accepted with varying degrees of success, not necessarily with roundhouse kicks but with other techniques and/or objects).
