It happens to the best of us, whether we drop it in a puddle, use it in the rain, or knock over a glass of water – but what if there was a simple at-home solution that was easier than putting a sack of rice in it?

A YouTube video that has been viewed 45 million times promises to do just that through sonic vibrations that will theoretically “push water out of your phone speaker, completely removing the water from your cell phone speakers.”

Hundreds of thousands of viewers are praising the product in the comments, swearing that the two-minute video has fixed their phones after spills, drops, or other liquid mishaps.

But skeptical technology experts wanted to test the so-called panacea for soaked devices, whose new editions lose their water resistance over time.

According to The Verge, speakers work by pushing air around them, meaning this force could remove water from a phone’s speakers.

“The lowest note the speaker can produce, at the highest volume it can play,” Eric Freeman, senior research director at Bose, told the outlet. “That creates the greatest air movement, which pushes the water trapped inside the phone out.”

However, one caveat is that smartphone speakers are small—unlike larger speakers that can produce deep, loud sounds—and YouTube videos cannot reproduce “really deep bass.”

In theory, however, the sounds from the YouTube video should act like the water ejection function of the Apple Watch.

“It’s just a certain oscillating sound that pushes the water out of the speaker grills,” Carsten Frauenheim, a repair technician at iFixit, told The Verge. “I’m not sure how effective the third-party phone versions are, as they’re probably not optimally tuned. We could test it.”

Working with the team at iFixit, The Verge writer David Pierce selected four phones he was “willing to destroy in the name of science” – the Nokia 7.1, iPhone 13, Pixel 7 Pro, and Pixel 3 – and submerged them in a UV bath. The next day, the team checked to see if water had entered the phone and not come out.

While the Pixel 7 Pro was dry, the Nokia was “ruined,” while the iPhone 13 and Pixel 3 were left with some liquid.

When the YouTube video was played on the phones, a detailed video of the device speakers showed water droplets spurting out. However, this did not resolve other water-soaked parts of the phones, such as the USB port or SIM card slot.

“I think (the videos) kind of work,” Chayton Ritter, an engineering student who works with iFixit’s editorial team, told The Verge. “It can’t hurt, but I don’t think it’s the ultimate solution or a way to get all the fluid out.”
