Rubbing both pieces cause each piece to have a negative charge.
When two parts have the same they repel each other, so holding one piece up tot he end of the other piece would push it away.
Because one piece is held in the middle by a string, it would rotate the piece in a circle.
If they held the piece to the other end of the one held by a string it would start to rotate in the opposite direction.
When hockey players push the puck along the ice it slides causing heat which melts the ice causing the friction against the ice to be less.
Friction stole the book's kinetic energy, and turned it into heat energy ... which blew away in the breeze.
