Abstract
A decorative tank includes a main body and an air-introducing means. The main body, which has a bed portion and a wall portion, defines a water reservoir therein. The wall portion of the main body has a substantially upright-sloping surface formed thereon. The wall portion defines a passage therein which extends substantially upwardly from a lower end to an upper end. The passage communicates with the bottom portion of the water reservoir at the lower end. The water reservoir contains a quantity of particles therein which have a specific weight greater than water. The wall portion of the main body has a window portion through which the view within said main body can be clearly seen from outside. The air-introducing means can introduce air to the lower end of the passage, so that the particles, such as sand, can be carried upwardly together with water by air to flow along the passage and to finally exit from the upper end of the passage, to allow the sand to fall along the substantially upright-sloping surface of the wall portion of the main body to give the appearance of a waterfall.
