The idea is to prototype a time piece that functions like a sand clock. The design consists of two containers connected through pipe underneath. When all the water moved from one to another container, the container would slowly move down and touch the ground which has spring underneath. Therefore, the water would go the other way around.
Water as the material inside is chosen in order to give aesthetic effect for the user. The water movement including its ripple would be projected to its surroundings and give amusing visual effect. Ones may be agree that water and lighting are such a decent combination.
