about? Crazy jets of fiery stuff spraying everywhere, lava flowing, and maybe Hawaii?

But as scary as volcanoes are, they're actually an amazing window into the science and history of the earth.

So come hang with me in my neighbor Vulcan, and my aunt B, as we dig deep into the Earth's

crust on this very hot episode of Who Smarted.

Coming! Hello. Hi neighbor. Uh, we haven't officially met. My name's Vulcan. I just moved in

next door. Nice to meet you Vulcan. Cool name. I'm your trusty narrator. What's up?

Well, I have luck. Would have it. I was baking a cake when I realized I was all out of the key

ingredient. I feel so silly. No worries. What do you need? Sugar, flour? No, no, I've got that.

I need two gallons of lava, huh? Come again. I need two gallons of lava. Can you spare some?

Lava? Yeah, my new girlfriend is coming over. For dinner and I promised I'd bake my famous lava cake

for dessert. Oh boy. You mean like fiery molten crazy hot lava? Can't make a lava game without lava.

I'm a rat. Sorry. What did you say your name was again? Vulcan? Oh, like the Roman god of fire Vulcan?

Whoa. Good guess. That's me. Have we met before? No, I've just heard your name before.

I'm flattered. Uh, so about that lava. I don't have any. Shoot. Oh, well it's too late to go to

the store. My date's ruined before it has even begun. Hang on. Don't throw in the towel just yet.

I think I know where to find some lava. Really? Yeah, but we're in for quite a trip. We need to find

out where lava comes from, what it's made of, and how and why it exists in the first place.
