Systems, methods, and articles of manufacture provide for a mold system for molding structures (e.g., sand castles) from one or more various types of molding substances (e.g., sand, clay, snow). In one embodiment, a mold system comprises a split mold comprising at least two mold sections. In one embodiment, a modular mold system allows for different types of mold sections with corresponding joining elements to be joined together to create forms for molding various types of structures. In some embodiments, mold sections are configured to facilitate the breaking of a vacuum created when molding substances are packed into the mold system, thus making it easier to separate a mold from the formed structure.

A mess-free sand play device is disclosed herein. The mess-free sand play device in accordance with aspects herein has a tray having a planar base and an upstanding wall rising from a perimeter of the planar base. A quantity of loose, granular sand and a moveable device or internal stylus are enclosed within the tray and a cover, the cover having a clear or transparent window through which the loose, granular sand and the moveable device or internal stylus are visible. The moveable device or internal stylus has a foam tip and a magnetic top, which allows for it to be manipulated with an external stylus having a magnetic tip. The foam tip of the moveable device or internal stylus, when pulled through the layer of loose, granular sand, forms a path in the layer of loose, granular sand, the path forming a desired pattern in the layer of loose, granular sand.

A raised bed garden and sandbox system comprised of rails and connectors, where the rails are connected to each other via a hinge-like system and joined by the insertion of tubular connectors that are circular in cross-section and open at one end to allow the insertion of a framework for a cover. A structure to support a cover is described, consisting of multiple cross-members, where one end of each cross-member is inserted into a connector and the other end of the cross-member is inserted into the opposite connector. An alternative design for a structure to support a cover is described, where for each cross-member one end is inserted into a connector and the other end is inserted into a central hub. A pattern is described to ensure that the raised bed garden or sandbox is arranged into a regular polygon. A heating element consisting of an electrical resistor arranged in a plane is described, as well as an planar insulator sized to fit the raised bed garden. An improvement in the design of a blow-molded rail provides higher quality and shorter cycle time by forming a partial bushing in the male end of the rail instead of a full bushing.
