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 excessively. The result is that the water begins to warm due to
disolved minerals (providing ions). The elevated temperature increase
conductivity, increasing heating, until finally the water starts boiling. The
vaporizor "shuts off" when the level of the water drops below the electrodes.
If electroplating is a mixture of water and electricity, then so are most
batteries.

Subject: Water + Electricity
Greetings,
A friend of mine is teaching elementary school students on the dangers of
mixing water with electricity. However, he also wants to show examples of
situations where water and electricity mix, yet does not cause a problem.
Does anyone have any examples?
Also, does anyone have a great elementary school explanation as to what
elements or conditions are needed to be present before water and
electricity become dangerous?
All responses are appreciated.
