A container, that includes a transparent portion, which reveals an interior portion of the container, an access aperture communicating with the interior portion of the container, and a lid adjacent the access aperture. A first liquid component is placed into the interior portion. A second liquid component is poured into the interior portion. The lid of the container is closed to fully enclose the first and second liquid components. The components are agitated until the first and second liquid components are a mixture of uniform color, without an appearance of marbling and swirling, when viewed through the transparent portion of the container. The lid is opened to expose the mixture of uniform color. The mixture of uniform color is poured from the container into a receiving structure. The mixture of uniform color is transformed into a closed-cell polyurethane structure within the receiving structure.
