How did Zecora make water out of nowhere? HOW?
Maybe she just teleported the spilled water from the table back into the glass. Or drew water vapor out of the air.
How did such a powerful amulet wind up in a curio shop?
A bigger question, I think, is: Why does the owner even display the amulet if he thinks it’s far too dangerous to sell?

He doesn’t actually care; “No, it’s far too dangerous” is just what he says to encourage potential buyers to fork over even more cash.

"What about Red Herring, ma'am?"
"I'm not sure. Is Red Herring a red herring? Or is it the fact that we're supposed to think Red Herring is a red herring that is actually the red herring?"
"Or perhaps the fact that you're supposed to think Red Herring isn't a red herring makes Red Herring a red herring after all."
"We're talking serious meta-herrings here."
That would be running a punchline into the ground.
