Probably because they can. Before we had transistors we had vacuum tubes. In them electrons move between objects. They also move electrons between objects in particle accelerators. If your community has a cancer center in its hospital, you might ask them if you could have a tour of the radiation therapy department. The "linacs" used to treat cancer accelerate electrons.
The electrons move from the balloon to your body.
Electrons move between the hair and the balloon.
ELECTRONS
It has electro static cells that form when re-peatedly rubbed wich creates friction ending with a attraction to the item of your choice. When you rub the balloon you create a static charge that is positive and the attraction that makes it stick to the wall is because the wall has a negative charge and like poles attract.

An insulator
It's due to static electricity build up. The balloons have become charged with electricity and it is the same charge on both balloons (either positive or negative). Opposite charges attract, identical charges repel each other.
The friction between two different materials in the right combination (this case your hair and a rubber balloon) causes free valence electrons (the electrons in the outer most orbit around an atom) to move from one item to the other, causing an excess of electrons (negative charge) in one and a deficit (positive) in the other. When put near the paper with an opposite charge, the paper will jump to the balloon. Opposites attract.

All matter contains positive protons and negative electrons. When you bring a positively charged balloon close to a neutral wall, the wall becomes polarized. The electrons in atoms move colser to the balloon, making the near side of the wall seem negatively charged and farther components seem positive charged. This has a net attractive force on the balloon.
The balloon has a greater affinity for electrons so it obtains a negative charge after being rubbed against the sweater. The balloon, containing a highly negative charge, sticks to the wall because it is attracted to the positive charges in the wall (opposites attract). After a while, the balloon's extra electrons move to the wall and both objects become neutrally charged. Lacking any significant attraction, the balloon will fall off the wall.
Both are originally have equal electrons and protons. After rubbing, electrons move to the duster, from the rod. The duster, as it gains electrons, has more electrons than protons, therefore becoming negatively charged. The rod, losing electrons, becomes negatively charged. then, the rod is able to momentarily pick up little bits of paper for short periods at a time.
They move with the wind
