Would you bury
yourself underground for 50 hours
with only a walkie-talkie
as your lifeline?
I know. Me neither.
But there's one guy who did it
on purpose and survived.
We're talking about you, MrBeast.
"Seal me up."
But how did he do it?
Could anyone survive this challenge
if they had a big production
crew like MrBeast?
Or does it require
a certain set of skills?
There’s only one way to find out.
Grab a shovel and pay attention,
because we’re about to go six feet under.
Jimmy Donaldson
is a brave young
American YouTube star,
better known as MrBeast.
In 2021, he subjected himself
to one of the most terrifying nightmares
anyone can experience,
being buried alive in a coffin.
"Bury me alive."
It's a challenge that
even the most famous
and experienced
escape artists in history
had never managed to pull off.
But he did.
Today we take you underground
to explain his secrets of survival.
Start the clock,
because you have to stay down there
for 50 hours.
The timer is set,
and the dirt is piled on top of your coffin.
You've prepared for the challenge
mentally,
so you stay calm
for the first few hours.
But soon,
you notice you're running out
of the most essential resource.
Oxygen.
With a body inside,
the average coffin
can hold about 820 L of air,
but only one-fifth of that
is breathable oxygen.
Someone like you and me
consumes 0.5 L of oxygen every minute.
Do the math.
You have only five hours
before you die of asphyxiation.
I'm sorry, buddy.
But let's assume that, like MrBeast,
you've installed a ventilation system
that provides you with fresh air
so you can make it through
to the end of the challenge.
You can survive 50 hours
without drinking or eating,
but there's no point in
making this even harder, right?
So you'd better prepare
some snacks
and drinks.
Remember to bring hand sanitizer,
especially for this next part.
Drinking also means you'll have to,
you know, take a leak.
You can't hold your pee
for more than 10 hours
without potentially
damaging your bladder and kidneys,
so you'd better have
a sealable container ready
so you can pee
without contaminating
the air inside the casket.
As for poop,
you can follow MrBeast's advice.
Just hold it in.
You've spent 20 hours
underground and counting.
At this point,
Jimmy was smelly,
experiencing back pain
and becoming claustrophobic.
He was also incredibly bored.
Having ways to distract yourself,
like with a radio,
can help with the boredom.
You can also bring a couple of books
to keep you entertained.
When Jimmy shifted himself around
to explore the other end of his coffin,
it was a move that might’ve been
the key to his survival.
After more than a full day lying
flat inside a coffin,
your lungs are being held down
by gravity
in a position that can lead to mucus
being trapped.
This can cause
fluid build-up in your lungs,
which could result
in a nasty case of pneumonia
waiting for you
when you make it back to the surface.
You're almost there,
but the last mile
is always the longest, right?
You feel anxious,
claustrophobic
and even experience a panic attack.
If that happens,
experts recommend
some techniques to stop it.
Closing your eyes
will reduce the stressful stimuli
around you.
Deep breathing will help
fight off the risk of hyperventilating.
You can also focus on an object
and describe it to yourself in detail.
That will clear your mind
and help you cope with anxiety.
The fireworks go off.
You've made it.
”So long. Oh my gosh”.
Feel free to cry for joy
as a tractor pulls
you out of your temporary
early grave.
You might want to celebrate
with a special dinner.
Speaking of fireworks,
how about trying
the hottest pepper on the planet?
People all over the world
are undertaking this challenge,
but many don’t know
that they can actually die
doing it.
Do you want to know how?
Just keep watching.
