A tennis ball support device is disclosed which is adapted to hold a tennis ball in mid-air without any contact thereof by the blowing of air from underneath. This device includes a housing having side walls being generally cylindrical and a top and bottom. A blower is positioned securely with respect to a mounting platform generally centrally within the housing and the housing defines apertures for receiving and expelling air therefrom. An outlet controlling device is affixed to the upper end of the housing within the outlet aperture to control the distance and speed of upwardly moving air used to support a tennis ball. The devices within the support device are resiliently mounted or insulated with respect to one another such as to minimize sound transmission between parts of the support device to provide a quietly functioning design. Also insulation is used throughout the chamber defined within the housing to further minimize noise and vibration. The height of the ball can be controlled by movement of the outlet control device or a change of shape or design thereof.
