The hand crank is rotatable and is connected to a main drive shaft anddrive gear. A propeller which is positioned within the housing and above the drive shaft isdrivingly interconnected with the drive gear by a gear train for rotation at a speedgreater than the speed of the shaft. A bubble dipper is secured to the drive shaft forrotation through a reservoir of bubble- forming liquid within the housing and for forminga film of the bubble- forming liquid.
