The clock does not need a battery at all. By filling the bottle on the back of the clock with water, the time and date can be clearly displayed. Water, the source of electricity, triggers an internal chemical reaction. The chemical reaction is mainly the top 20 elements of the periodic table, free of heavy metals and not harmful to the environment (mainly magnesium and aluminum, which are common in our lives).
This product can work normally by adding tap water. If the product display is dim or disappears, water or other liquids (except corrosive liquids) should be added until the liquid fills the positive and negative terminals in the container.
Note :(different types of perfume can be added according to personal preference)
