The Measurements Say So

It's me, says Terence. But I look like a pobblebonk.

Yes, I could tell it was you by your head, says Belle.

Are they your pyjamas? asks Leonardo. 

No, says Terence. My red drink spilled on my shorts.

We heard, says Belle. And some of the red drink seeped under our seats and made the floor sticky.

Sorry, says Terence. The red drink didn't have perfect balance.

Would you like to see my designs for circular hinges? asks Leonardo.

Why would I? asks Terence.

Leonardo is not used to this kind of response.

For your egg box doors, says Belle.

I've changed everything, says Terence. I only need one big door.

How big? asks Leonardo.

He is willing to make alterations.

Jump up onto the armrest, says Belle, and you two can discuss the plans quietly. I'm going to sleep.

Okay, says Terence.

He climbs up onto the armrest in his pobblebonk jersey.

Leonardo shows him several circular hinges that he has come up with. 

Choose one, says Leonardo.

Terence chooses.

Now I'll just alter the radius, says Leonardo.

He crosses out a number and writes a different one.

It still looks the same, says Terence.

But it's bigger, says Leonardo. The measurements say so. Now you can use it for one big door in your egg box. Would you like a lock too? I have a great idea for one. 

Yes! says Terence.

He watches Leonardo draw a perfect circle with a circular hinge at the top and a circular lock at the bottom.

Or, says Leonardo, we could split the door in half horizontally, with a fixed bottom half that can't open, so the eggs can't fall out, as long as the box is kept upright. What do you think?

That depends, says Terence.

Which is quite a good answer.

On what? asks Leonardo. The size of the eggs I suppose, or whether the box will be tilted during egg collection.

Honestly, says Belle. Some people are trying to sleep here. Have you finished?

I don't know, whispers Terence.

What don't you know? asks Belle.

If the egg box will be tilted, says Terence.

They're cuttlefish eggs, says Belle. The box will be in the water. It's bound to get tilted.

Now we know, whispers Terence.

Now we know, agrees Leonardo.
