1620 Cubic Feet (2006, destroyed)

Plastic sheet, packing tape, vacuum motor, hose.
(72 x 72 x 540 inches)

The inflated volume is six feet long and wide, and forty-five feet tall, exactly fitting the dimensions of the void created in the center of the spiral staircase. Because the plastic was not rigid, as air filled the volume, it flexed around the wooden stairwell's railings and into the stairwell itself as if spilling over or pressing into a separate void-space. The column of plastic slumped over when it reached the top of the room, unable to sustain its own weight without the support of the surrounding staircase. The object is kept inflated by a constantly-running vacuum motor. At the same time an exhaust tube allows air to flow out of the piece to prevent over-pressurization.
