Static Electricity with a soda can
What we are seeing is a property known as electrostatic induction. Left to its own devices, the can has no net charge - it has an equal number of positive and negative charges, distributed evenly throughout the material of the can. But because the aluminum can is an electrical conductor, some of those charges can be free to move around if acted upon by an outside force. When the negatively charged rod is brought near the can, the electrostatic force (or Coulomb force) that this negative charge exerts affects the atoms in the can. Some of those free electrons, also carrying negative charge, are repelled and move to the far side of the can. This leaves the side of the can nearest the rod with a net positive charge, which is now attracted to the rod! And so the whole can, being quite lightweight, can slowly start moving towards the rod.
