Abstract
A display providing the illusion of a stream of liquid coming from an unconnected spigot, the stream flowing into a receptacle. A transparent tube, hidden within the stream, runs from the receptacle to the spigot to carry the liquid upwardly to the spigot. A second tube, colorless and transparent, surrounds the stream of water, to prevent evaporation and accidental spillage on a person. A small colorless and transparent air tube runs from the receptacle upwardly between the inner and outer tubes to a mixing chamber at the top of the tubes. Air is drawn upwardly through the tube by a Venturi effect within the mixing chamber and mixes with the water. As a result, the downwardly flowing water is filled with bubbles and can be seen.
