Cardcaptor Sakura, Season One

Yamazaki:
Do you know what the origin of the water yo-yo is? It was first seen in the Edo era, and it was more like a regular summer past time for peasants.

Sakura:
Wait, did they have rubber way back then?

(Sakura holds up the water yo-yo)

Sakura:
This is rubber, right?

Tomoyo:
Yes.

Yamazaki:
Yeah, so they used to make it out of glass.

Chiharu:
It's getting pretty fishy now...

Sakura:
Glass? Then they couldn't play with it like this- (Sakura bounces the water yo-yo into her palm)

Yamazaki:
No, the classy people invented ways to play with it without breaking it.

Chiharu:
It's a lie, a lie.
