In the lecture demo with the plexiglass rod, rabbit fur and tinsel, why did the tinsel flare out when charged, as opposed to doing something else?
The negative charge added to the tinsel when the rod touches it spreads out everywhere in the tinsel (the tinsel is a conductor, meaning that charges can flow freely). The extra negative charges repel each other and try to get as far away from each other as possible… so the strands of the tinsel flare out to get as far away from each other as they can.
