A flotation recreational device consists of a buoyant vessel having a semispherical exterior surface and a sufficient internal area adapted to accommodate an operator. The vessel is configured to have a geometrical center which is a metacenter of a spherical buoyant body serving as a base of the partially-spherical exterior surface. The center of sphere is spaced from and located above the center of gravity of the operator, so the radius of sphere is greater than the height of said center of gravity. The stability of a vessel-operator system is determined by a stability of a distance between the metacenter and the center of gravity of the operator. The vessel can be in the form of a circular shell, an elliptical shell, or a barrel.

A method and apparatus for weed removal, wherein using a depilatory method (new use) with an extension spring having an arcuate axis and being driven in a rotational sliding motion relative to the soil-bearing weed to be removed. For this purpose the apparatus is equipped with a spring (), having an arcuate axis that is bent at 180 degrees and the spring is made in the shape of a spring of variable rate, so that the spring has a large diameter in its middle zone and conically reduced cylindrical ends of smaller diameter.

A personal propulsion apparatus for controllable gliding a rider over a water surface includes a buoyant body unit, a power unit and a thrust assembly with at least two independently pivotable thrust nozzles. An intake unit having receiving and directing portions. A height adjusting arrangement is formed with the directing portion. During motion over the surface of water, the intake unit with the height adjusting arrangement, remains submerged. Upon excessive lifting force being generated the height adjusting arrangement is elevated above the water surface, causing entry of air into the power unit, resulted in decreasing the thrust and lowering the height adjusting arrangement below the water surface into the submerged position, so that the rider assumes the longitudinal motion over the water surface.

A personal flying water jet apparatus consisting of two autonomous units: one is a towing inflatable tube (A) (and so on) equipped with water jet nozzles () directed downward and mounted on both sides by means of brackets (); the other is an inlet port () fixed on a tow line (A) and connected with the nozzles () by mean of lay flat discharge hose (). While the tube is being towed, the kinetic head appears and pressurized water is discharged at the nozzles () making a thrust, so the rider () will fly. Additional versions of the apparatus' performance are possible, such as: Inflatable can be made in the shape of a life jacket (B) with the nozzles () on a Backpack, so the rider () will fly in vertical position; water-supply of the nozzles () can be realized by means of a water pump () mounted on an unmanned tug (B) connected with the nozzles by means of the hose (), so the rider (), while flying, remote controls the propulsion (), including the driven water pump (); water-supply of the nozzles () can be realized by means of a water pump () mounted in a pool (), so the rider () will fly around the pump () tied to a rotating swivel fitting (); the water pump () performs like a motor pump () and can be mounted directly on the Backpack (B), but pump inlet is connected to the inlet port () (located under the water's surface) by means of the hose ().

One is a floating platform made in the shape of a segment of a sphere (so in the shape of spherical dish,—previously in the text: “Dish”). The radius of the sphere is longer than the height of the center of gravity of the child (). The Dish () is equipped with a round rim () and a flexible bellow () located on the edge of the Dish ().The other is a round pool (), mainly inflatable, for placing the Dish (), so the pool () diameter is about that of the submerged Dish diameter, corresponding to the sum of the Dish's weight and the child's weight.The floating platform can be made also in the shape of a zone of a sphere (so in the shape spherical barrel,—previously in the text: “Barrel”). The Barrel's () radius is equal to the Dish's () sphere radius and the Barrel's () width is equal to the Dish's () diameter.For either the Dish () or the Barrel () the round pool () can be formed by placing a circular float () on the surface of the water, for example a swimming pool ().
