ABSTRACT:
A toy floats on the water surface of a pool. A hydraulic jet propulsion unit is connected to the bottom face of the toy. The propulsion unit includes a rigid tubular member with a straight central portion, a forward right angle elbow and a rear exhaust tube extending at an acute angle to the central portion. The forward elbow is connected by a flexible hose tether to a water source. Thee hose is anchored at an intermediate point to the pool bottom. The rigid tubular member is rotatably mounted in a housing so that it is free to rotate about the long axis of its straight portion. Water forced through the rigid tubular member is ejected from the exhaust tube, forcing the toy forward. When the elbow is vertical, the toy moves straight forward. When the elbow is rotated to the left or right by the pull of the tether, the exhaust tube also rotates to left or right causing the exhaust jet to leave the stern at an angle, turning the toy as it moves forward. This creates automatic random forward propulsion with random left and right turns with various angles for an unusual and appealing continuous unattended operation.
