Well, first we better get the spelling right. It's generally two words, not one, in referring to any kind of water glass.

This is a guess), but I would wager that Jackie didn't mean the water glass that's part of a formal place setting. Too easy.

I'll bet she's referring to either the water glass that measured time or the one for underwater observations.

Guess we'll have to wait till she returns, huh, of troy?
