The invention is remote-controlled water toy that has an outer shell that is a continuous and external surface, a plurality of apertures in the outer shell that allow water to infiltrate the outer shell, and an interior volume that collects and stores water that has infiltrated the outer shell. The remote-controlled water toy can shoot water, be shot at by other similar vehicles, retain water that hits them directly in the interior volume, continue to be operational after being hit, and sink or otherwise become deactivated when a predetermined volume of water has infiltrated the exterior shell.

An apparatus or educational toy comprising a main body (120, 220, 320, 520) and a drive mechanism (140, 240, 340, 540), wherein the drive mechanism (140, 240, 340, 540) comprises a reservoir (142, 242, 342) for storing a driving liquid, a discharge outlet (144, 244a, 244b, 344, 544a, 544b) through which the driving liquid is discharged from the main body (120, 220, 320, 520) to generate a driving thrust, a liquid delivery path (146, 246a, 246b, 346) for delivering the driving liquid for a reservoir outlet (148, 348, 448) to the discharge outlet (144, 244a, 244b, 344, 544a, 544b), and a threshold setting device (147, 347); and wherein the threshold setting device (147, 347) sets a threshold thrust level so that the driving liquid is to pass from the reservoir (142, 242, 342) and discharged from the discharge outlet (144, 244a, 244b, 344, 544a, 544b) upon reaching the threshold thrust level during operation.
