This experiment was first carried out by Lord Armstrong in 1893. Read the historical tales of this experiment.
De-ionized water acts in a special way when exposed to high voltage. This experiment uses two normal household drinking glasses filled with de-ionized water and a wire in each glass from a 20kV flyback transformer, I used one of my older drivers for the supply.
7th may 2009
The drinking glasses are filled to the brink with de-ionized water and put close together, the water will climb up the sides of the glasses and form a bridge of water between the two. Very carefully the glasses can be pulled apart to gain a longer bridge, but eventually it will not be able to sustain due to gravity.
I was able to make a 12 mm long water bridge as seen in these images.

This is an easy and fun experiment to do if you already have a high voltage low current power supply at hand, reproducing experiments by scientists is a great way to acknowledge their discoveries and learn some new theory and history.
