A fluid compression system includes a gaseous fluid compressor having a fluid inlet and a compressed fluid discharge, a prime mover coupled to the gaseous fluid compressor in driving relation, and a demand sensor positioned to measure a compressor demand and output a demand signal. The tactile elements are positioned on an outer surface of the football in locations that correspond with locations that contact the hand of an individual when properly throwing a football. Other bearing retaining arrangements are disclosed including the use of tapering races. The plunger mechanism is actuated via rotation of the inner tube using a control switch. The first layer of nanoparticles is chemically modified using functional surfactant molecules applied thereto, such that a second layer of nanoparticles may be formed on top of the first layer and chemically bonded thereto via the functional surfactant molecules.
