Why does a balloon that is rubbed on someoneâs shirt stick to a wall at a party?

When we rub balloon on a shirt the balloon will steal electrons from the shirt and the shirt will become positively charged and balloon will negatively charged. The reason that the balloon will stick to the wall is because the negative charges in the balloon will make the electrons in the wall move to the other side of their atoms and this leaves the surface of the wall positively charged.
