An automatic bubble/water gun employs an arrangement of gears and linkages to continuously produce bubbles. The components of the bubble/water gun are grouped by function and pre-assembled before installation into a bubble/water gun housing. An electric motor imparts motion to the gears and linkages so long as a trigger switch is closed. The bubble/water gun also includes a manually operated water gun. The water gun employs a manually operated water pump to produce a stream of water in addition to the automatic bubble-producing function.
