What is an object that does not allow electricity to flow through?

An object that does not allow electricity to flow through easily is an insulator. It is so hard that it often won't go through at all. Sometimes you find an exception, like lightening. There is nothing that electricity cannot flow through altogether.


Why can't electricity go through rubber?

Rubber is what is known as an electrical insulator. The difference between insulators, which block the flow of electricity, and conductors, which permit the flow of electricity, lies in the availability of mobile electrons in the material in question. Electricity is composed of moving electrons. Some materials, such as metals, contain electrons that are easily moved, hence electric currents move easily in those materials. If a material does not have electrons that are easily moved, then it resists the flow of electrons.
