Bottle Top Challenge: Mariah Carey, Justin Bieber and Ryan Reynolds take part in new viral craze

Challenge is to remove the cap from the bottle without using your hands

Celebrities around the world are taking part in a new viral craze where people challenge themselves to knock the cap off a bottle without using their hands.

The Bottle Top Challenge, which has featured on various gaming shows for years, has now taken on new life on social media, with a number of famous faces – including Mariah Carey, Diplo, Ryan Reynolds, Ellie Goulding, Justin Bieber and Lizzo – having a go.

Reynolds really went for it in terms of production, although that was likely more to do with the fact that he was blatantly using the craze to advertise his own brand of gin, but ended up smashing the bottle.

Bieber, who infamously challenged Tom Cruise to a fight last month before backing down, imagined the bottle top was "Tom Cruise's face" before successfully swiping it off with a swift kick. Kendall Jenner took part in the challenge on a jetski. Obviously.

But it was Mariah Carey who has won the challenge (at least according to her fans), after she posted a video showing her removing the cap "with her voice".

While the video looks highly suspect, you've got to at least applaud Carey's sense of humour – not to mention the note she hits – as she is filmed singing at a high pitch while the bottle cap trembles and then flies off.

A bashful-looking Carey then beams and walks off-camera.

Her tweet has become one of the most viral of 2019, with more than 1.5 million likes and 25 million views on Twitter.
