Static electricity is an imbalance of electric charges within or on the surface of a material. There are positive and negative charges. It can also be created by friction, rubbing two different materials together.

Static electricity is the buildup of electric charge on the surface of objects. It is created by the contact and separation of materials. Static electricity is caused by the buildup of electrons on one surface. When two surfaces are rubbed together, electrons are transferred from one material to the other, creating a static charge. Static electricity can cause a number of effects, including attraction and repulsion of objects, electrical shocks, and sparks.

Static electricity can cause fires. It can cause the buildup of flammable gas in an area to ignite if it reaches a certain level of voltage. Static electricity can be used to create levitating objects. This is known as Static electricity can also be used to create 3D holograms. By manipulating tiny particles of dust with static electricity, images can be created that appear to be floating in the air.

Question: Why do balloons stick to your hair after you rub them on your head? Clues: • Rubbing the balloon transfers electrons from your hair to the balloon. • This creates an imbalance of electrons, which creates static electricity. • Opposites attract, so the balloon is attracted to your hair. In pairs: Select and solve one of the tasks: A. Draw a picture of the static electricity between the balloon and your hair. B. Explain how the static electricity works using words and diagrams.
