A building set includes a plurality of building components. The components m ay be configured so that one or more predefined structures may be constructed with a set of the components. For example, the set of components may be configured any number of predefined structures may be constructed, such as a table and chairs, a boat, a plane, and so on. The components may be made fro m a composition including polyolefin. The polyolefin may have a density in the range of about 1 pound per cubic foot (lb/ft) to about 9 lb/ft3. As such, th e components are compressible, resilient, and elastic. One or more of the components may include a first retaining element, and one or more of the components may include a second retaining element. The retaining elements ar e configured to engage together for securing or coupling the components together. For example, the retaining elements may be defined by one or more dimensions, with at least one of the dimensions of one of the retaining elements being greater than a corresponding dimension of the other retaining element. The retaining element with the greater size may be urged or inserte d into the other retaining element, thereby being compressed. When received within the other retaining element, the compressed retaining element exerts a spring force, thereby causing the components to be retained by friction between abutting surfaces |
