    Abstract: A bubble making toy comprising a rotatable ring member (34) having a hole (36) for forming a bubble. A pivotable wand element (32) is mounted near the outlet side of the hole and can be pivoted across the face of the hole by actuation of a trigger (12). The toy further includes a pump (14), also actuated by the trigger, for directing a soap mixture from a reservoir (16) to the wand element.
