How does a shadoof work?

Bobby: How does a shadoof work?

Zane: Well a shadoof works by propping a long stick on like a large table made of other long sticks. The long stick thats on the table like thing has a weight on one end and a bucket tied to the other end. They remove the weight and the bucket goes into the Nile and then they pull the bucket filled with water to drink. does that answer your question bobby?

Bobby: Yeah it does!
