Hopefully you're not
claustrophobic.
I will try to stay in there
for as long as I possibly can.
There's a lot of pro athletes
that can't do it.
- Okay. When you said how long
  can you--
- No. Meaning they jumped out,
- like, 30 seconds.
- Yeah, 30 to 40 seconds
  they come out.
But the way this helps
in my next stunt...
- Mm-hmm.
- ...Is when I'm going up
  on the balloons...
- Uh-huh.
- ...And riding all the way up.
Basically every 1,000 feet,
you lose three and a half
degrees.
On my first jump that I did
from 25,000 feet,
I had a full face mask on.
And the first breath
that I took,
the whole thing iced over,
so my sky dive, when I was
jumping down,
I had to, like, look through
this little hole.
- No. Ice while you're out
  of the plane.
- Yes.
Your breath becomes ice
immediately.
- That's crazy.
- Me and Jake are going to take
  our temperature
because once we go in
the cryogenic,
I want to see
if our temperatures drop, so...
- ( beeps ) 
- It will be 98.3.
 ( beeps )
- Good.
- That's lit.
We had one professional boxer
yesterday tap out.
- Wow.
- So he got knocked out
  in one round.
- Yeah.
- Wow.
Wow. this is crazy
right now.
One, two, and...
- You doing okay?
- Yep.
- Okay.
- You're halfway there.
He's get 45 seconds left.
He's doing great.
He's starting to shake.
All right, good job.
- Oh. Oh.
- Wow.
- That's amazing.
- ( groans )
He said that was one level.
What's the next level of that?
- More than ten.
- More than ten?
- Just crank it to the highest
  for me.
- Yeah.
In the stunt,
I do have to learn when
I'm going up to these heights,
how to stay
completely coherent,
and hypoxia kicks in much
quicker when you're in
an extreme condition.
- How you doing in there, bro?
- ( chuckles )
  It's good.
He said it was good.
We'll do two in a row.
Two in a row?
Now it's good.
( chuckles )
Three?
This man is trying to go again
for three.
- You want to go
  for a third time?
- Yeah.
Okay.
Just wanted to triple check.
He's gonna be in there
for nine minutes.
Dude.
This is the longest that I think
anybody would ever think
about doing.
You got about 25 seconds left,
bro.
I do not know how.
That was insane.
- Wow.
- That was good.
- Let's see if the temperature
  dropped.
- ( beeps )
- Look. Too low.
- Low.
  ( laughter )
That wouldn't even give you--
a low.
- Yo.
- It's good.
- ( beeps ) 
- ( laughter )
You did it, bro.
Yeah, you're gonna be good.
