Static-E Attraction on Knitting Needle

Quote Quote by Greg-ulate View Post
The presence of the electric field form the static charges can polarize the charge on the water droplet. Opposite charges are attracted and move to the face closest to the needle and like charges are repelled and move to the far side of the droplet.
I think your first sentence might explain it. The charged rod is brought near to but not touching the end of the droplet dispenser. This attracts charge in the water towards that end of the dispenser. As droplets are dispensed, they carry with them some of this charge, making them charged droplets. So simple!
