YouTuber MrBeast breaks down in tears as he is buried alive for seven days

Popular YouTuber MrBeast spent seven days sealed inside a coffin and buried underground in a jaw-dropping stunt which has already garnered a staggering 85 million views in just six days.

While the mere thought of being buried alive is enough to send shivers down the spines of most claustrophobes, MrBeast, real name Jimmy Donaldson, spent a week in a box underground to entertain his 212 million YouTube subscribers.

The stuntsman, who has often gotten in trouble for his daredevilry, stated that the stunt caused him "mental agony" and urged his followers to not try the same at home.

Like Uma Thurman's character in 'Kill Bill', MrBeast voluntarily buried himself ten feet underground for a seven-day endurance test. Throughout, his team closely monitored his condition via multiple cameras installed inside the modified coffin. 

"I spent 7 days buried alive,” reads the title of the video shared on YouTube by MrBeast. 

The video opens to show MrBeast inside a transparent coffin, stocked with essentials - including dry foods and water - being slowly lowered into the ground.

As the video goes on, his team, who comprise his childhood friends and fellow YouTubers, uses 20,000 pounds of dirt to effectively seal the YouTuber below the surface. 

Throughout the video, MrBeast experiences emotional breakdowns, candidly revealing details of his daily routine, including bathroom activities, and expresses a loss of desire to communicate.

Towards the end of the video, he says, “It’s hard to describe what the sun looks like after not seeing it for seven days straight.”

While underground, the suit-clad online megastar continued communicating with his overhead team via walkie-talkies as they all engaged in friendly banter and silly jokes, one which involved MrBeast fooling around with a photo of one of his friend's mother.

During several gripping moments in the challenge, including when he was being freed from the casket and the dirt, the YouTuber started to cry, also admitting that he didn't understand why he was crying during these moments.

On the night of day four, MrBeast said emotionally, “I hope tomorrow’s easier. It’s a weird feeling. I am very tired, but for some reason I can’t sleep. I don’t know. I’ve never had this happen before. Why am I crying? I don’t know.”

After 7 gruelling days of being buried alive, his friends, who had brought along an excavator, started to dig MrBeast out.

But one risk remained - After lying down for 7 days, if MrBeast stood up rapidly, fatal blood clots could form in his body, so the group first brought in a medic to check his vitals.

After getting the green light, the YouTuber finally came out and celebrated hitting 200 million subscribers.

MrBeast's challenges have often been criticised by fellow YouTubers as being fake. His charity efforts, too, have also been panned severally by people accusing him of exploiting people's poverty and situations to create content and generate views.
