Stan runs a comb through his hair then brings it near several strips of paper. The paper starts to move without Stan
touching it. His little sister is amazed and wants to know how the trick works. Stan says that the comb has a static
charge, but doesn't know how it got its charge. What would you tell Stan?

Protons from Stan's hair transferred to the comb giving it a negative charge.

Electrons move from the comb to Stan's hair giving it a neutral charge.

Electrons from the paper strips jumped to the comb causing the strips to move.
