Pretty good episode, but I have one big scientific nitpick:
The water on the ceiling had much higher electrical conductivity because it had been on the ceiling.
Pure deionized H2O is not conductive. Water's conductivity is due to dissolved ions. Tap water has a bit more ions, so it's more conductive. If you have very hard water, it'd be quite conductive.
Ceiling water has been on the ceiling and possibly in the walls in contact with drywall and other nasty stuff. It's going to have a lot more dissolved solids in it, so it's going to be far more conductive than average tap water.
I cringed at the conductive water thing.
