Abstract
A bubble making toy includes a bubble making device having an impeller and a bubble wheel including a plurality of apertures. The bubble wheel rotates within a bubble making fluid reservoir for forming a film of bubble making fluid over the apertures. The impeller is arranged to rotate within an impeller housing and delivers a flow of air through the apertures for forming a substantially continuous stream of bubbles. Each of the impeller and the bubble wheel are driven from a drive axle to which at least one wheel is secured, and preferably, each are driven at a respective rotational velocity that is a respective multiple of the rotational velocity of the at least one wheel.
