Static electricity. After a plastic comb is used for straightening dry hair (or rubbed on wool) it becomes electrically charged. The charges create an electric field in the surrounding space. When the comb is brought close to small bits of styrofoam, the electric field induces charge separation in the bits thus leading to a net electrostatic attractive force between the bits and the comb. | |
