ABSTRACT:
An apparatus for creating freestanding columns of compressible substances such as snow and sand. These freestanding columns can then be sculpted into any desired shape. The apparatus is placed on level ground, filled with the compressible substance after which the substance is compressed using hands or other implements. The operator then rotates the apparatus by pushing horizontally on the handles, thereby causing the apparatus to rise vertically due to the spiral grooves on the inside surface of the apparatus. As the apparatus rises vertically, the column of compressed substance remains stationary while creating space at the top of the apparatus for the addition of more of the compressible substance. The process is repeated until desired height is reached.
