A collapsible container comprising detachable nested sections. The nested sections are tapered and coaxially disposed. Nested sections can be disposed within the largest section in its collapsed position. In its expanded position, the lower portion of a section engages with the top portion of the section immediately below the upper section to mechanically lock the sections into its expanded formation, such that the container is self supporting. The sections are detachable, and when overturned and removed, can be used as a mold for creating parts of a sand castle. The removed sections can be joined in sequence to other removed section to vary the volume of sand being molded. The sides of each section comprise decorative molding shapes or patterns for creating parts of a sand castle. The bottom surface of the mold further comprises mold shapes for creating part of a sand castle when overturned.
