(Amaya) So our next step is we're going to make prototypes out of, like, cardboard boxes.

- You have to do a little bit of math here: 8 feet into thirds.

- Yeah.

- How many inches is 8 feet?

- 96.

- One wall size is 32 inches long.

- That looks right.

And then the other side.

- Yeah, we have to do the same thing.

Like that.

So it's a confined space just for you.

- Good job.

- All right, let's fold.

(Amaya) We're each gonna take one home and do little, like, video diaries.

And then we can make this one like this.

(Lily) Our goal is to spend, like, 15 to 30 minutes in there each day.

And we're, like, gonna customize it to our needs and, like, what we want in there.

- I think that'll help us in the next phase by mimicking what the astronauts would do.

(Amaya) I'm excited to, like, tell my sister to leave me alone and to, like, give me some privacy.

- Yay.

- This was actually... - There we go.

- This was a good one.
