Telekinesis is the paranormal ability to move objects (and people) with one's mind. This ability is held by witches, but most notably, Sarah and Nancy.
When she arrived to her new school, she used telekinesis in class to telekinetically rotate a pencil on it's tip. When she lost concentration, the pencil fell. This marks Sarah as the first witch to use telekinesis in the movie.
Nancy Downs is also a user of this ability. Most notably, she used this power to kill Chris by opening a window and pushing him out of it. Secondly, she used it to unlock a bathroom stall that Sarah was in.
