Here's why:

* Metals have free electrons that can easily move throughout the material. This allows electricity to flow through them easily.

* Insulators, on the other hand, have tightly bound electrons that cannot move freely. This prevents electricity from flowing through them.

Therefore, a fork is a conductor of electricity.

Important Note: While a fork is a conductor, it's important to be extremely careful when handling forks near electrical sources. Even a small amount of electricity can be dangerous.
