Al Jazari calls this mechanism as strange and surprising in a single mechanism. He used this mechanism both for fountains and Zamr devices. In this mechanism, the flow of the water gets interrupted and a thin pipe fills a spoon. This device is designed and fabricated to be well-built and interactive for the students. The mechanism feeds the water coming out of the thick pipe into the fountain pipe system or the air pressure chambers of Zamr devices. The mechanism directs the water flow out of the thick pipes to the chamber underneath the device and pumps up to discharge. In this way, the device functions in a closed system without getting connected to plumbing system of the home. The device uses the same water through recycling. In addition to the panel that comes with the device, a separate panel with text and figures as well as balance equations explains the phases of the operation of the device just like Al Jazari designed.
