Dynamic ball game for two players in weightless environment with floating balls in box moved by air impact into opponent's goal in opposite box walls, with four orthogonal box edges locating each one nozzle

摘要

The game uses balls (3) in transparent box (1,2), which has apertures in two front faces serving as goals (4), while four orthogonal edges are each fitted with a nozzle (8). A pump (5) compresses air and moves it in closed tube system (6). Preferably air is contained in tube system by a non-return (7) and a release valve (9), which can feed air at each nozzle into box at a given time point to direct targeted pulses onto balls. Typically all transparent box faces (2) are made of break-safe, transparent plastics. Independent claims are included for training apparatus for leg muscles and a measuring apparatus.
