Last night, my 3-year son decided to make a "magic" potion after
watching a Harry Potter movie. He tapped the two sinks in the bathroom
on the second floor to fill them with water and "forgot" to turn them
off. As a result, the magic potion spilled on the floor resulting in a
3'x3' size puddle for some 20-30 minutes. The water found its way to
the first floor ceiling. We discovered this accident after seeing that
water is coming through the chandelier hole on the first floor which
is directly below the bathroom on the second floor.

Things I've done so far: I removed the chandelier from the first floor
to let the water out. I deployed two fans - one on second floor to dry
out the carpet (an area of 1'x1' of the corridor adjacent to the
bathroom got saturated) and another one to dry out the ceiling on the
first floor. This morning I inspected the ceiling on the first floor.
I can see a few small wet areas mainly around the chandelier outlet
but no other serious damage at this point. I open up all windows on
the first and second floor and switched on the ceiling fans. Our house
was built in 2000.

What possible interior and exterior damage should I expect and what
should I do from here on besides sending the magician to Hogwarts?

If possible get a strong wet vac and get all the water that you can out
of the carpet. Sooner the better, so it doesn't get musty or soak into
subfloor any more than it has.

Keep the magician away from the fans and the wet areas. Have the
magician explain again what he was doing and make a video. Someday, it
will be hysterically funny )
