Why do socks stick together?Although they are much too small to see, atoms make up everything around us. And atoms are made of protons (positive charge) and electrons (negative charge). In the dryer, as your socks rub together, electrons move from the atoms of one sock onto the atoms of the other. As one sock becomes more loaded with electrons than the other, an attraction is created, causing one sock to stick to the other. As they say, opposites attract!
