Abstract
A ball launching device for children that has an outer housing, an inner bowl and a launch assembly. The inner bowl has an inner surface with an outwardly curved cone shaped wall and a vertical linear wall. The launch assembly is connected to the bowl. When the bowl rotates at high speeds, the curved cone shaped wall enables balls to ascend up the inner surface and eventually propel out of the ball launching device.
