Cork material is an impermeable, buoyant material, a prime-subset of generic cork tissue that is harvested for commercial use primarily from Quercus suber that is endemic to southwest Europe and northwest Africa. Cork is composed of suberin, a hydrophobic substance, and because of its impermeability, buoyancy, elasticity, and fire resistance, it is used in a variety of products, the most common of which is for wine stoppers.

A floating dock is a platform or ramp supported by pontoons. These are usually joined to the shore with a ramp that rests upon the dock on rollers, to adjust for the vertical movement of the dock. The dock is usually held in place by vertical poles embedded in the soil under the water or by anchored cables. Frequently used in marinas for small boats, this type of dock maintains a fixed vertical relationship to watercraft secured to it, independent of tidal, river, or lake elevation. It is less suited for larger craft as the docks cannot support large structures or cranes. In some regions of the world, a floating dock is called a pontoon.

The Great Crested Grebe (Lophæthyia cristata) is a fresh-water, migratory, diving bird of the family Podicipidæ. It has a duck-like body, brownish and white plumage, long neck, short wings, no tail, and large, flattened toes furnished with lobate membranes serving the purpose of webs. Most of its life is spent in fresh water lakes and ponds, but in winter and during migration, it often resorts to the sea. It is an excellent diver. The nest is made of rushes and other aquatic plants and usually floats on the water, being loosely anchored to weeds and grass. It is found in nearly all parts of Europe and Asia.
