Abstract
A ball launcher for launching a plurality of soft closed cell plastic compressible balls, one ball at a time, by causing a plurality of balls in a line, one ball at a time (each time the plunger is moved back and forth), to squeeze past a constriction at the front of the launcher. The front most ball in the line of balls, to be launched, is urged against the constriction by a resilient biasing carriage engaging the rear most ball in the line of balls.
