- So I'm here today in Florida filming with Kevin,
more commonly known as The Backyard Scientist.
- That's right.
- And today we're gonna take these two live grenades,
and we're gonna be dipping 'em
in this tub of liquid nitrogen.
So go ahead and hand 'em to me.
And then dude, baby alligator.
(grenades bouncing)
(water splashes)
(classical uplifting music)
So now we're both about 15 feet away,
except I'm on land with a grenade on land,
and Kevin is in the water with a grenade in the water.
So the question is, which one
of us has a better chance of survival?
Take a moment to decide, do you dive
on the pool deck or jump in the pool?
We both had very different theories for survival.
So as firm believers in the scientific method,
we decided to test out our hypotheses.
So we devised some experiments.
But before I get to those, I think it's important
to understand how a grenade actually works.
