- Dr. Ocho should be here any second.

Wait, I hear footsteps.

[dramatic music] ♪ ♪ - Hi, Mom!

[all exhale] - Hi, kids.

Um, this isn't the best time to visit.

We're expecting an important visitor.

- Very important, Dr. Ellen Ochoa is about to walk in.

She is the director of the NASA Johnson Space Center.

- We know, we already met Ellen.

all: Ellen Ellen?

- Yeah.

She said, call me Ellen.

Probably because it's her name.

- Uh, the Ellen Ochoa we're talking about is a famous astronaut and inventor.

- And she really likes lemonade.

- And she loves to play the rain coat.

Uh, I mean, the flute.

- [laughing] It's all true.

Hey, kids.

all: Dr. Ochoa!

- Hi, Dr. Skelly, Rafferty, Bergs.

- Hi, Dr. Ochoa.

I see you've met my daughter.

- Ah, Sydney's mom.

What a bright, curious, fun kid.

They all are.

I had so much fun with these guys.

Amazing treehouse.

Jet's rocket chair.

Wow.

- Um, treehouse?

- Oh, yeah, we played in the treehouse, flew to outer space.

[laughs] - [nervous laugh] What fun.

So we're excited you're here, and ready to show you our design for the Orion rocket part.

As you can see, we're still working on the design.

The rocket part vibrates a lot when it reaches the upper atmosphere.

- That's a big problem, I hear ya.

- Right.

Here's our design in action.

[computer beeps] - You know what, the kids and I were just talking about this, and I think I have an idea.

You see, Jet showed me his very innovative rocket chair.

- Oh, yeah!

- When Jet tried to fly it too high, the chair also shook a lot.

The kids tried different things, and they got the idea to try a valve spigot thingy, as the kids called it, from their lemonade machine.

- And this spigot thingy helped stop the vibrating?

- It did.

I suggest we try it for your design here.

- Okay, but it could take a while to design it.

It would be good to see one.

- [squeaks] - Here you go.

One valve spigot thingy.

- Wow, what's next?

Jet flies his rocket chair into the upper atmosphere?

- Well, that's my plan.

- I've added the spigot to our rocket design.

Let's see if it works.

[computer beeps] all: It works!

It's not vibrating!

- What a wonderful, simple solution.

Thanks, Dr. Ochoa.

Brilliant.

- The real credit goes to your kids.

They had an engineering problem, but kept trying until they found a solution.

- We all worked together and solved the problem.

- It's an honor to be nominated.

- A toast to excellent work by Sydney, Jet, Sean, and Mindy.

all: Excelsior!
