Transcription: When two objects are rubbed together, electrons may move from one to the other. When a plastic comb rubs on cloth, for example, it picks up extra electrons from the cloth, giving it a negative charge. Small pieces of paper normally have no overall charge. When the comb is brought close to the paper, however, the negative charge on the comb pushes electrons away from the atoms in the paper, creating positive ions at the top of each piece of paper. The positive ions and negatively charged comb attract each other, and the pieces of the paper stick to the comb.
