(water splashing)

00:03

- So I'm here today in Florida filming with Kevin,

00:06

more commonly known as The Backyard Scientist.

00:08

- That's right.

00:09

- And today we're gonna take these two live grenades,

00:11

and we're gonna be dipping 'em

00:12

in this tub of liquid nitrogen.

00:13

So go ahead and hand 'em to me.

00:15

And then dude, baby alligator.

00:18

(grenades bouncing)

00:21

(water splashes)

00:28

(classical uplifting music)

00:35

So now we're both about 15 feet away,

00:37

except I'm on land with a grenade on land,

00:40

and Kevin is in the water with a grenade in the water.

00:44

00:46

of us has a better chance of survival?

00:48

Take a moment to decide, do you dive

00:50

on the pool deck or jump in the pool?

00:52

We both had very different theories for survival.

00:54

So as firm believers in the scientific method,

00:57

we decided to test out our hypotheses.

01:02

So we devised some experiments.

01:04

But before I get to those, I think it's important

01:06

to understand how a grenade actually works.
