ABSTRACT:
A method and apparatus is disclosed for adjusting the resilience of a hollow ball having an internal pressure. A ball, particularly a tennis ball, is held in a confined position. A mixture of inflating medium and sealant material is injected from an aerosol container into the tennis ball. A ball test gauge is incorporated within a ball holder to enable the player to continuously and simultaneously determine the necessity for increasing or decreasing the internal pressure of the tennis ball in order to achieve the desired resilience. The frame structure is provided for fixing the storage canister or aerosol container in a stationary relationship with respect to the ball holder. A combination of elements is then provided for adjusting the internal pressure within the tennis ball.
