LOS ANGELES, CALIFORNIA — In the summer of 2019, the internet was dominated by the “Bottle Cap Challenge,” a global trend where celebrities and athletes showcased their dexterity and martial arts skills by attempting to spin-kick the cap off a loosely closed bottle without knocking the bottle over. While the world watched action stars like Jason Statham and martial arts fighters land perfect roundhouse kicks, pop icon Mariah Carey stepped into the arena and won the entire competition without breaking a sweat, using her legendary vocal range as her “secret weapon.”
On Sunday, July 7, 2019, the singer posted her submission to the viral challenge. The video begins with Carey standing in front of a wine bottle, striking a poised, mock-karate stance, implying she was about to join the physical feat. Instead of performing the strenuous kick, the ultimate diva simply put a finger to her ear—the iconic gesture signaling an impending high note—and let loose.
Mariah Carey unleashed one of her signature whistle register notes. The piercing, high-frequency sound, delivered with maximum vocal power (a G#6 note, according to later fan analysis), causes the bottle cap to spin, lift, and magically fly off the bottle. Carey then smiles, looking bashful, and walks away as if to say, mission accomplished, no physical exertion necessary.
The Power of the Whistle Register
The video, which quickly amassed tens of millions of views across platforms and was universally declared the “winner” of the challenge, was a perfect blend of high-level comedy and musical flexing. It confirmed Mariah Carey’s status as a vocal legend whose instrument is so powerful, it can seemingly manipulate the laws of physics.
The technique she used to “kick off” the cap is the whistle register, the highest vocal register, which utilizes only the back portion of the vocal cords to produce notes at exceptionally high frequencies, a technique synonymous with her early career hits like the song “Emotions.” While experts acknowledged that the frequencies required to physically shake a cap loose were likely aided by clever video editing, the humorously audacious use of her five-octave voice proved her diva status effortlessly.
The Bottle Cap Challenge was popularized by celebrities like Jason Statham, John Mayer, and Kendall Jenner, who all relied on intricate physical movement. Mariah Carey’s non-physical, yet ultimately victorious, entry redefined the challenge, showing that sometimes, the greatest power lies not in strength, but in a world-class, world-stopping voice.
The video is often cited as one of the funniest celebrity entries into a viral challenge.
