Ok, so, I'm doing a little project on water molecules. More specifically, on, well as the title suggests, realigning them. Now, at first, i thought it had to do with magnetism, when in fact magnetism has to do with electron spin rather than charges. As I tried using an electromagnet, for the electric field, nothing worked. The only thing that seemed to work at realigning the molecules was through static electricity from a glass rod or comb. However, I am not trying to redirect the movement of a stream of water, but to just rotate the molecules, in say, a jug (quasi-stationary). Any suggestions on how? Also, from my reading of van de graaf generators, they don't seem to have to same pulling capabilities as a comb does, with static electricity. Some equations pertaining to how to calculate the charge needed and force acting upon them would also be nice.
