Al Jazari designed a device that can be filled up from a whole on its top with four different drinks and water into separate reservoirs. After that, the fountain allows the guests to get drinks in a controlled fashion. The fountain allows mixing drinks as the guests prefer. The fountain mixes the drink in pre-specified rates. The guests may also prefer a single drink without any mixture. There are two engineering marvels that Al Jazari innovated in this device which is designed to be experimental and interactive. The mechanism on the neck of the cube is a multi-channel direction control valve. Al Jazari's automata offer 15 different unmixed or mixed drinks depending on how much the drinker wants to mix using this valve.
