The invention is directed to a ball support practice tee whereby a ball is suspended on a column of air. The apparatus involves a housing having an annular cone shaped nozzle extending upwardly therefrom. Within the nozzle is placed a blind core which prevents axial flow of air from the nozzle, but will cause air to flow between the nozzle and the inner surface of the nozzle to produce an annular flow of air from the nozzle, thus suspending a ball. A compressor is placed within the housing for producing a supply of air under pressure through the nozzle.

A ball practice tee comprising: a housing; an air compressor positioned within the housing; and a vertically oriented frusto-conical outlet nozzle of shallow taper connected to the compressor and opening from the housing, the nozzle having a coaxial blind core fixed within said nozzle and forming with the nozzle and annular outlet passage whereby air will pass from said nozzle only between said core and said nozzle, and whereby upon actuation of the compressor a laterally expanding annular air flow issues from the nozzle to stably support a ball in mid-air centrally above the nozzle.
