HOLY WATER
Another integral
part of the basic Slayer's kit. Holy Water is basically water that has been
blessed by a preist. (There is probably more to it than that, and I apologise
if I offend anyone) There is a possible problem with Holy water though,
Priests (or other men of the cloth) might get suspicous when you come in
every week with dozens of bottles of Evian to bless. (This is something
that isn't ever mentioned in 'Buffy' and I think it really should be addressed.)
However, you might be lucky and have some of your Irish family within the
Catholic priesthood/nunhood (like I do)
How To Use
You throw it in the face of a vampire and it makes thier skin melt and
then they die (as far as I can tell from the horror movies) That's all
there is to it. Just remember to take the top off the bottle, before you
throw it, or use a bottle that easily breaks.
Best (so far) Vampire death:
Helpless (season three) Buffy tricks Zackary Krallik into drinking a glass
of Holy Water and he burns away from the inside.
Other possible uses:
You could always drink Holy mineral water.
You have plenty of bottled water if there is ever a water shortage.

Ooh, look! Someone's
got themselves Holy water on tap!
