Rubber creates sparks when rubbed against the floor due to the buildup of static electricity from friction. This occurs as electrons are transferred from one insulator to another, resulting in a discharge when the electric field strength reaches approximately three million volts per meter. While rubber is commonly used for shoe soles, it is not a perfect insulator, which contributes to the sparking phenomenon. Understanding this process is crucial, especially in environments with flammable materials where even small sparks can pose a danger.
