Reviews and comments:
As a 7th grade student at Salk School of Science in Manhattan, I decided to build a Kelvin water dropper as my exploritorium project. So far it works great! Our question is if a spark will discharge earlier when we use liquids with a wide range of acidity. I believe the liquids with higher acidity will discharge earlier, what do you think?
I was bothered by your comments that the two sides of the water would be 'randomly' charged. The ratio of water to heavy water is 1 to 7000, and because the source water will polarize, you will get more - out of the south source, or (or east if in that direction). It is the delta between the two streams that you are playing with.
