From the brains behind brains on, this is the Moment of Um.

Um, um, um, um, um, um, um, um, um, um, um, um, um. Moment of Um, comes to you from APM Studios.

I'm Crocket Greff, the rocket chef from planet Calorpus.

Um...

Welcome to my space kitchen, where I'll whip up any kind of rocket you need. I just got a call

for my good friend, Colorpan Adventure, video game hero, and adorable alien, Fuzzbut

Pickle Star. She's looking for a new mixture of fuel for her spaceship. I think I can come up with

something to keep those hardworking engines of hers well fed. Let's head to the pantry for

ingredients.

I know we're going to need something spicy to get the engines really hot.

Maybe Venusian chili flakes.

Oh, wait, there's still some of that fire sauce I got from that mini mart next to the asteroid belt.

And we're going to need some prune juice and baking powder, obviously. And wait, what?

That's not how rocket fuel works on your planet? Huh, interesting. Maybe we can trade recipes.

It's a good thing Naomi asked about this, too.

There are three kinds of rockets, and they would use three different kinds of fuel.

My name is Eric Axall, and I'm an aerospace engineer for NASA.

The first kind of rocket is a liquid-fueled rocket, and so that's a rocket that has fuel tanks on board, and that fuel could be things like hydrogen, liquid hydrogen fuel, or a liquid kerosene fuel.

Kerosene are essentially very highly refined oil, essentially.

So those are two common fuels that are using a liquid rocket.

And then oxygen is a common oxidizer that you would burn with that fuel to make the hot gases that come

out of the engine at the end. Another kind of rocket is called a solid rocket. A solid rocket,
