Intended as an object that can be easily constructed, the conical object designed by Polish designer and architect Hugon Kowalski, uses common materials and processes to aid its creation.
A PVC fabric which easily absorbs water is sewn into a cylinder, then soaked and hung by clothes pins from the top while, at the same time, a hoop of PVC piping is attached to the bottom.
Due to gravity and the below-zero temperatures, the material adopts a form that resembles a tree. The structure then sits over the top of a light, which illuminates it in the night. To preserve the structure you can spray it with water forming a thin layer of ice that glistens in the light.
