The document describes a science experiment to test how electrons move in an electric circuit using a fluorescent light bulb, balloon, and wool sweater. The student hypothesized that rubbing the balloon on the light bulb would cause the light to flicker repeatedly, but when they rubbed the balloon on their head and sweater first before the bulb, the light only flickered once, allowing them to conclude that the electrons jumped from their hair to the sweater and then to the light bulb.
