Experiments from Ania&Jessika

To draw the balloon charged by the friction to the tiny trickle of water. The trickle of water is leaning toward the balloon. Description: This happens due to polarization of water molecules in an electric field of the balloon. A water molecule forms an electric dipole. Negatively charged balloon attracts the positive charges in the water molecule, water molecules are oriented such that thier positively charged side is closer to the balloon.
