A Trinity senior puts electrostatic charges to work by spinning a plastic bird without touching it. One object will move away from another if both objects have the same electrical charge. By moving a charged rod near the charged plastic bird, the bird is moved faster and faster. By switching the rod to the other side of the moving bird, the bird slows down, is brought to rest and then spun in the opposite direction. In the end, the student’s arm gave out before the charge did.
