Riddle: What gets whiter the dirtier that it gets?
Answer: Chalkboard

Need a hint?

Teachers write on it with chalk.

Answer and explanation (spoiler!)

The answer is a chalkboard (blackboard).

A chalkboard starts out dark. The more people write on it with white chalk, the “dirtier” it gets, and the whiter it looks.

Most things look darker when they get dirty, so the riddle turns that idea upside down.

Are there other answers?

A blackboard or chalkboard is the classic answer. Some people suggest a black car covered in dust, which also works!
