The Bottle Cap Challenge is a viral trend that started sometime in June 2019. While the origins of the trend are uncertain (though The New York Times credits taekwondo champion Farabi Davletchin with jump-starting the challenge), the feat itself is fairly straightforward: Participants try to remove the cap from a bottle in extravagant ways, usually using martial-arts-style kicks.The challenge is particularly popular on Twitter and Instagram, and most videos are accompanied by #BottleCapChallenge. It has also spread on other social media sites, notably Reddit, and numerous celebrities have participated.So, how are people kicking the caps off of bottles? Most loosen the caps so they’re barely on the bottle in the first place. To prevent the bottle from falling over, participants usually secure the bottle (or have a friend hold it, slightly off camera).Here’s action star Jason Statham successfully completing the challenge.

Mariah Carey took part in the challenge with this (somewhat dubious) video.

Some challenge attempts are less successful than others, as actor Ryan Reynolds showed.#BottleCapChallenge #Glass @AviationGin pic.twitter.com/joM20RhUid— Ryan Reynolds (@VancityReynolds) July 3, 2019Unsurprisingly, the #BottleCapChallenge hasn’t come without a little internet controversy. Twitter users recently pounced on Kendall Jenner for taking the challenge at sea, depositing a plastic cap into the water—Jenner did say, however, that the cap was recovered.Rap legend Snoop Dogg posted a profanity-laced tirade on Instagram, asking, in so many words, why people are engaging in such tomfoolery.We have no idea, Snoop. Our advice: Don’t worry about it. Either you enjoy this trend, or you don’t—and if it’s not your thing, nobody’s forcing you to participate.
