Equipment for building sand castles can include a body having a single, monolithic, hollow structure with a vertical axis and a sidewall that is continuous and uninterrupted in a rotational direction about the vertical axis. The sidewall can include an inner pattern that is castle-like in appearance. The inner pattern can form an outer pattern in sand located inside the body. The body also has an open bottom, an open top that is completely unobstructed and has no inward protrusion, and a top radial dimension at the open top is smaller than a bottom radial dimension at the open bottom such that the body is tapered. A handle extends from the body adjacent the open top. The handle can be used to vertically lift the body from the sand located inside the body to form a freestanding sand castle without support from the body.

A tool for writing with flowable sand includes a tube of flexible plastic that may be filled with a mixture of sand and water (the consistency, controlled by the user, sufficient to allow the sand to flow, such as when making a drip castle at the beach). A writing tip is attached to one end of the tube, where the user provides sufficient pressure to the tube so that the flowable sand exits through a properly-sized aperture formed in the writing tip. An end cap may be attached to the opposing end of the tube. Either the writing tip or end cap are removable (or both are removable) to allow for re-filling of the tube with flowable sand.

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., hydrophobic sand). In one embodiment, a mold system comprises a hinged mold comprising at least two mold sections, each mold section joined by a hinge to at least one other mold section. In one embodiment, the mold system may comprise a mold cap, a removable joining key, and/or a molding tool comprising at least one compactor portion.

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.
