  1. “What kind of coins are those?”

    Unsolicited advice: we need to lock that camera down on a tripod, or anything stable really. It’s really tricky to motivate a question from a short video. Even trickier if the camera is unfocused and bobbing around.

    Can’t wait to see what you come up with next time.
