Negative electrical charge on water?? Help!

Hello everyone:

I have heard about paint sprayers that put a charge on the paint as it exits the sprayer - the charged paint is then attracted to the metal surface being painted, provided the metal surface is charged with the opposite charge.

My question is this: Is it possible to do the same with water, except without any wiring? For example, if I wanted to put a negative charge on falling rain to repel it from a metal surface that is also negatively charged? Is it possible to remotely charge water - maybe with an electron gun or something similar? Is this even possible?

Thanks!

Try the Kelvin water dropper as explained in Wikipedia. There are numerous videos on the internet showing the actual gadget in operation. You can make one of these at home. You get positively charged water as an extra bonus with this!
