In class we have been doing science and learning about electrostatic force. Our first experiment was when we tried to give a ruler and electric charge to pick up small pieces of paper. The reason it could pick up the paper was because the electrostatic force enabled the paper to defy the gravitational pull. Then we went into groups and got a balloon and some bubbles and we rubbed the balloon on various surfaces (including our heads!) and blew bubbles on to the surface. The force we created helped to fight gravity.
