A craft stick is made of wood. Wood is generally considered an insulator, meaning it does not conduct electricity well.

Here's why:

* Atomic Structure: Wood is composed of organic materials with tightly bound electrons. These electrons are not easily freed to carry an electrical current.

* Moisture Content: Dry wood is a better insulator than damp wood. Moisture can make wood more conductive, but it's still a relatively poor conductor compared to metals.

Therefore, a craft stick is an insulator.
