​Task

​Scenario: An alien has landed on Earth. It's never seen toast, a toast, or even bread before. It wants to make toast. You need to give it step-by-step instructions - in the right order - to help it make a slice of buttered toast.

Rules

• The alien will only do exactly what you say.
  If a step is vague(not specific enough), missing or out of order, it could go very wrong.
