They key though, is the induction created to the water droplets which you can read about it here (http://www.eskimo.com/~billb/emotor/kelvin.html)
What is happening (my guess) is that the nylon when rubbed is positively charged (lost electrons) when placed near the tip of the syringe, the water is positively charged because its electrons are given to the nylon needle, creating a positive charge in the water. The Teflon needle, on the other hand, is a very negatively charged material (gained a lot of electrons through rubbing it with paper) and thus the positively charged water is attracted to the negatively charged teflon needle and the orbit through these opposing fields is achieved in microgravity!
