Compressed air mechanism for propelling toy halls, constituted by a sealing plug provided with two holes, an upper one in which an air intake tube is housed whose outer end is open, and the inner one in the form of "duck bill", is equipped with a tongue that prevents the circulation of air in the opposite direction; and a smaller lower one, open, for the exit of the air, located below the waterline of the ship to which it is applied. This plug has a balloon whose entrance mouth is the ship to be applied so that the force of expansion of the air does not exceed the dimensions of that cavity, and that of understanding is made entirely.
