When you rub a balloon on a cat, it charged.
Charged balloons can be attached to walls or cat.
The charged balloon rolls down as it discharges after a certain period of time.
If you peel off a thin vinyl wrapped in a book or candy, the vinyl may stick to your hands and may not fall well. Also, if you comb cat or dog in the dry season, it may become a booth. This phenomenon occurs because electricity is generated by friction between two objects. This is called triboelectricity because of the friction between the object and the electricity. Triboelectricity is also called static electricity because it does not flow and stays on an object.
Generation of triboelectricity
The material consists of microscopic particles called atoms. The atom consists of a (+) nucleus, and a (-) charged electron. An atom does not exhibit electricity as a whole because the amount of (+) and (-) charges is the same.
When two objects that are not electrically charged are fractioned, electrons move from one object to another. At this time, the object that received the electrons becomes (-) electricity, and the object that lost the electron becomes (+) electricity.
For example, when you comb a cat's fur with a plastic comb, the electrons move from the cat's fur to the comb, the comb is charged with (-), and the cat's fur is charged with (+).
