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 of the thyristors.

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.
