Jala Yantra is an ancient Indian astronomical instrument used for measuring time and determining the positions of celestial bodies. It consists of a large circular vessel filled with water and a small float with a pointer attached to it. The float is placed in the center of the vessel and the pointer is aligned with the North Star. As the Earth rotates, the water in the vessel moves and the float rotates with it. The pointer indicates the time and the position of the celestial bodies.
