Watch the clip and describe what's happening.
Narrate it as if you're the one doing it, and you're explaining it to a friend on the phone who wants to follow along and do it themselves. Not just what happens, but how it's done:
- Which way the tap turns
- How the plate is held
- How much pressure goes into the scrub
- When you'd stop and check something
They can't see any of it. They don't know the room, they can't see the hands, they have no idea what's being held at any moment. Everything they know comes from what you write. When they're done reading, they should be able to picture the whole thing and repeat it themselves.
Write it in the present tense, in the order it happens.
