Abstract: A water spouting bop bag includes an inflatable housing having ballast in a lower portion thereof. A spray head is connected at the top of the housing and water is delivered thereto from a garden hose via a tube in the housing. With water spouting from its top, a child punches the bop bag from an initial upright position, so as to tilt the water spout onto another player. The weight of the ballast restores the bop bag (and the water spout) to the initial upright position.

Abstract: A water toy includes an inflatable housing having ballast in the lower portion thereof. A spray head is connected to the top of the housing and water is conveyed to the spray head from a garden hose through a tube in the housing. With water spraying from the top of the housing, the toy can be hit from an initial upright position so as to tilt to various angles but will resume its initial upright position.

Abstract: A method of removing contaminants from the surface is disclosed. The method comprises coating the surface with a surface active agent having a first surface energy and into which the contaminants are combined, applying thereover a higher surface energy colloidal sol and then allowing sufficient time for the first surface energy material with the contaminants combined therewith to migrate through the colloidal sol so as to remove the contaminants from the immediate vicinity of the substrate surface. The surface may then be treated by exposing it to an acid or base to remove the migrated surfactant layer thus removing the trace of contaminants.

Abstract: A method of selectively depositing a metal on a surface is disclosed. The method comprises selectively coating a surface with a surface active agent, having a first surface energy, to form a coated surface having a coated portion capable of burying a higher surface energy material applied thereto and an uncoated surface pattern not so capable. The selectively coated surface is then treated with a solution, having a second surface energy higher than the first, comprising a species selected from the group comprising (1) a species capable of reducing an activating metal ion to an activating metal and (2) an activating metal species capable of participating in an electroless metal deposition, to form a surface having the species deposited atop the uncoated pattern.

Abstract: A method is disclosed for selectively depositing a metal on a surface of a substrate capable of retaining thereon a colloidal activating metal for electroless metal deposition. The method comprises coating a portion of the surface with a copolymer of maleic anhydride and a vinyl monomer, wherein the copolymer coat is selectively incapable of retaining thereon the colloidal activating metal species, to delineate an uncoated surface pattern which is capable of retaining the colloidal activating metal species thereon. The selectively coated surface is treated with a sol comprising the colloidal activating metal species to deposit the metal species only on the uncoated surface pattern. Subsequently, the colloidal species deposited pattern may be exposed to an electroless metal deposition solution to deposit a metal thereon.
