Electrostatics experiment. Close-up footage of a balloon with an electrostatic charge being used to bend a stream of water. This experiment involves generating an electrostatic charge on a balloon or other object (by rubbing it with a suitable fabric such as silk). This ionizes the material (by removing electrons) and creates a positive charge. If the electrostatic charge is large enough, it will attract polar molecules (those that have unevenly distributed electrical charge) such as those found in water.
