This talent must be draining.

TikTok star Aidan Parker of Chicago is sharing the mind-blowing technique that allows him to polish off a glass of water, fruit drink or even a fizzy beverage in under 10 seconds.

The 23-year-old self-proclaimed “chugging influencer” has amassed over 776,000 followers on the platform with his H20 hack.

“I made a tutorial, and the next day, I woke up to like a million people who had seen it. I sort of let that snowball into being a chugging influencer,” Parker told Caters News, adding that he spent five days mastering the party trick during the COVID-19 pandemic.

On TikTok, Parker revealed he achieves the feat by “taking a little liquid” in his mouth to open his throat and looking up as he swallows.

Then, he’s prepared to consume a whole glass in one gulp. 

Parker’s followers challenge him to gulp down everything — from the “biggest glass in the world” to the smallest one to a can of Sprite — or use various straws to slurp liquids. 

He claims his personal record is five 500-millilliter bottles of water in just 10 seconds — but says “he’ll never do it again” due to safety reasons.

Parker’s viewers are both impressed and confused by his videos.

“This boy is HYDRATED,” one fan commented on a video of him quickly making three different liquids disappear.

“Where’d all the liquid go?” another stunned viewer wondered.

Reacting to another video, one supporter wrote: “That was both impressive and terrifying.”

“OMG! I want to look away, but I can’t,” a second exclaimed.
