ABSTRACT:
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.
