Being in a hot tub is a good example of water + electricity mix. However,
this can be a bad example when the hot tub has not been designed properly.
There have been many cases where high power pumps have been used and the

A common domestic application of water
I'm thankful every time I start my car that water and electricity mix so
well with lead sulfate to produce sulfuric acid. It saves a lot of hand
cranking.

I missed the gist of the question the first time around.
A common domestic application of water and electricity can be found in
vaporizors. The devices are simply two electrodes at power line potential
immersed in water. The active area is restricted a bit to keep the water from
convecting
How about monitoring moisture in soil, where the resistance between two
probes changes as function of the amount of moisture (water) present, due to
the minerals/elecrolytes that get disolved by the water when present. This
would be useful for figuring out when to water indoor plants, or perhaps

Greetings,
A friend of mine is teaching elementary school students on the
dangers of
mixing water
Magnetohydrodynamics (MHD) was first proved by placing electrodes across the
Thames
river and using Earth's magnetic field, a potential was measured due to the
flow of
water (containing naturally disolved ions ofcourse, or it wouldn't have worked!)
I forgot who the scientist was, I want to say
You can say that electricity in a bathroom can be dangerous,
and in the UK, we are very cautious in this respect:
You don't have a wall mounted light switch in a bathroom,
it is either outside the room, or the light is operated by
a pull cord operated switch on the ceiling.
You are not allowed to

One may remember the time that
huge rotary variable capacitors where used
(filled with salt water) to regulate the AC-motors
on Disney resorts attractions. They were boiling
all of the time.
Lifting one set of plates reduced the current and the motors.
This was definitely before the invention
How about submersible pumps - used in wells, sumps, and even decorative water
fountains. Another example would be immersion heaters, used from making a cup of
tea to keeping stock tanks and bird baths from freezing.

Hi Joe,
Postive results from the mixing of water and electricity can be found in
primitive desalinization techniques, and also as a means of generating
small quantities of hydrogen for laboratory use. Level detection in
water-containing vessels is another one as is the indirect heating of
water
