The Bottle Cap Challenge is the latest challenge among celebrities.
People like Jason Statham, Justin Bieber have gotten involved in the challenge and went on to nominate others to carry on the challenge.
The challenge requires that you kick the cover off a bottle without knocking down the bottle.
Mariah Carey was one of those who took up the challenge but, rather than kick off the cover with her leg, the singer did it with her voice.
This impressed numerous celebrities and they commented, crowning her the winner of the challenge.
Below is her video and reactions to it.
