Nina noted that all electrical plugs have three metal pins, while the rest of the plug is covered with plastic. Why?
Metal is used to make plugs' pins as it is stronger than plastic.
The metal pins are needed as conductors, so electricity flows through them while the plastic acts as an insulator and blocks the flow of electricity.
An electrical plug cannot be made of just one material so we need both plastic and metal.
Metal and plastic are the most popular materials and they are quite cheap to manufacture.
