28.5, which is the kids' size.

And this ball does not work very well.

So, it leaks air. So it's a good one to cut up.

We were just gonna throw it away just this last week.

Okay, here you go.

- [Lincoln] Here is my new hat.

How do you like it?

- [Man] Lookin' good. Okay. Alright, Lincoln.

Okay buddy. What do you think

is gonna be inside the basketball?

- No idea.

- [Man] Do you think it's gonna be the soccer ball is?

- No.

- [Man] No. Okay, let's check it out.

- [Lincoln] Nothing like the soccer ball.

- [Man] Toss it over for the last time.

Woo! Good throw. Ouch. That was a hard one.

We are going to use our knife again, if I can find it.

Oh, there it is, right in front of me.

Okay, Mr. Spalding.

Let's see if we can still see it if we go like that.

Alright.

This one has lines on it, so we can choose,

this is only straight -- ah, there's two straight lines.

We wanna leave,

we wanna make that be the front for the image.

So let's do this one.

(air escapes ball)

- That's a lot of air.

- [Man] A lot of air in that one.

This is one sharp razor. Wow.

It's like cutting through butter.

- This is a lot harder than buttle.

You said "butta." (laughs)

- [Man] Not buttle.

- This is a lot harder.

- [Man] Woo! Bingo. Pretty easy on that one.

No inner lining, like the other one.

- This one's a little bit bigger than my other one.

- [Man] Yup.

- A little big. Oh, look at this!

This is where you put the hole.

This is where you put it.

- [Man] Yeah, there it is. That's where the air goes in

and the needle goes in.

Look at it. It has like a cover over it.

You can see that.

It's like, I don't even know how the air goes in it,

because it... - [Lincoln] It's weird!

- [Man] What in the world? That is strange.

I don't know where the needle, how it goes all the way in.

Does it like, go through there?

- [Lincoln] That is so weird.

- [Man] We're gonna have to look that up on Youtube,

see if we can find the answer to that.

- See, 'cause here's the part,

and then you stick it through here,

and then, how do you get the air through?

It's cool. - [Man] That's cool.

Nice soccer ball hat.

I never would've guessed that that's a soccer ball.

Looks like the inside of a basketball, right there.

Doesn't it?

- [Lincoln] Yeah. But there's just this little lines.

And the outside is a lot different than it.

- [Man] Feel this soft leather.

It's like, some string or something glued on it.

Alright, well let's put it over here.

- [Lincoln] Aren't we supposed to have a football, too?

- [Man] Ooh. We need a football.

That's a good idea.

That's a lot of balls, though.

(Lincoln laughs)

Looks pretty good. I'm pretty pleased.

- [Lincoln] I'm pretty pleased with my hat.

- [Man] Alright, now it's time

to get to work on our projects for --

- Do you wanna wear a phone?
