摘要
The invention relates to a module with a hollow, flexible, cylindrical base, with nestable male and female ends, for use as a lightening accessory or belt for teaching swimming. On the basis of basic modules, the invention also relates to a series of moulded plastic pieces and a dense solid cylinder which make it possible to construct, according to the user's imagination, floating or underwater (sub-surface) plane or volumetric figures for playing and moving while gaining confidence in the water.
