A vortex connector for threaded plastic bottles is provided in which the connector has a pair of opposed recesses, each connecting with an inner female helically threaded recess, the recesses connecting to one another through an axially elongated constriction venturi. One of the bottles is partially filled with water. The so-coupled bottles are pivoted so that the water containing bottle is on top, the upper bottle is given a circular swirl or two and the water flows in a clearly discernable whirlpool or vortex from the upper bottle to the lower while the displaced air flows from the lower bottle to the upper through the thus-formed vortex in an educational or entertaining display.
