A method and apparatus for suspending and spinning a spherical object includes a blower operably connected to a power source providing a variable airflow of forced air, with an airflow unit coupled to the blower to form a contiguous assembly of the apparatus. The airflow unit may include an integrally formed tubular portion for directing airflow through a nozzle to suspend and spin the spherical object. The assembly is placed in a first angular orientation with respect to vertical for loading the spherical object over the nozzle, and placed in a second angular orientation with respect to vertical different from the first orientation for enabling a user to engage the suspended and spinning spherical object.
