<p>A toy which can be played within water consists of a cage made from four parallel bars (2) held together by a number of equally spaced rings (3). A model rocket (11) which is lighter than water is placed inside the cage and secured to the lower end by a catch (5). The catch can be released by a cable (8) attached to a handle (7) at the upper end of the cage. The toy is held below the surface of the water and when the catch is released, the rocket (11) shoots to the surface and up into the air.
