Abstract: Disclosed is a magnetic housing assembly which may have a housing body, a first capping structure; a second capping structure; a water-tight chamber defined by the first capping structure and the second capping structure; a ratcheting face; a magnet enclosed within the water-tight chamber; at least one ridge on the perimeter of the housing body, where the magnet can flip to reverse polarity within the water-tight chamber, where the ratcheting face is configured to allow adjustment of the assembly when connected with another structure also having a ratcheting face. Also disclosed is a system including a structure configured to house the plurality of magnetic housing assemblies while exposing a surface of the magnetic housing assemblies.

Abstract: Disclosed is an improved model kit including a plurality of support members for constructing a hollow frame upon which one or more surfaces can be constructed. The kit may include flat support members having slots, a first material which is in the shape of a flat sheet when fully extended, and which becomes self-adhering when saturated with water and which dries into a hardened material, a second material which becomes moldable when saturated with water and which dries into a hardened material, where the plurality of flat members are configured to interconnect with each other to form a hollow frame, where the first material can be laid over the hollow frame to form a first surface, and where the second material can be laid over the first surface to form a second surface. The improved model kit may be efficient, cost-effective, visually appealing, easy to assemble, and compact when stored.
