 Check the machines. These technicians was in this big old room. Interesting. Literally would check each machine one by one. You, as an observer, stands behind these ropes and you watch them. So I did that for like an hour or two. They did it all day. But you watch them check each machine and how they do it and they explain why they did it. Thanks, Deborah.
