Abstract: A method of manufacturing a snow sliding device includes forming a core by forming a core body including an outer surface including an upper surface, a lower surface, and a first thickness, and shaping the core body to include a second thickness; providing a plurality of elements, including a base with a sliding surface, and a top surface; incorporating in at least one of the core and the plurality of elements a first material, the first material exhibiting a shear rate-dependent shear resistance; and laminating the plurality of elements to the core.

Abstract: A motile buoyancy apparatus for use in a fluid. The motile buoyancy apparatus includes an outer layer, the outer layer having a performance surface. The motile buoyancy apparatus includes at least a portion including a first material. The first material is a non-Newtonian material. The at least a portion causes the performance surface to exhibit a shear rate-variable shear response.
