Abstract
A novelty drinking apparatus. The apparatus has a liquid reservoir with at least one liquid outlet (“first liquid outlet(s)”), ducted by a first ducting from at least one inlet (“first inlet(s)”) in the liquid pulled within the reservoir, at least one liquid outlet (“second liquid outlet(s)”) ducted by a second ducting from at least one inlet (“second inlet(s)”) outside of said reservoir yet in the vicinity of said first liquid outlet(s), and a chamber which holds said first liquid outlet(s) and said second liquid inlet(s) in a separated condition within said chamber. In the operation of the device, a suction applied at, on or about said second liquid outlet(s) induces a flow of liquid of liquid pulled from the liquid reservoir through said first and second ducting. The first ducting is arranged to direct the flow of liquid immediately before said first liquid outlet(s) in a direction to said second liquid inlet(s), such that the inertia of liquid leaving the first ducting through said first liquid outlet(s) establishes an unducted portion of said flow of liquid from said first liquid outlet(s) to said second liquid inlet(s).
