Do It for the Anthropologists of the Future

Describe something simple like how to microwave popcorn, how to get into a car or how to floss your teeth. Describe an every day activity in detail, as if you were writing directions for people in the future when no one knows what a microwave was or a car or tooth floss. Imagine you are writing it like a scientific report or technical support directions. Keep it simple and yet don't forget anything important.
