This sculpture is composed of a bird cage with 152 white cubes made of marble. The cubes resemble sugar cubes. The sculpture also has a thermometer, a piece of cuttlebone and a tiny porcelain dish.An explanation for the piece given by Duchamp involves the coldness of the marble cubes, the "heat-giving" properties of the sugar cubes, the thermometer evaluating temperature, and the sneezing that can result from cold. In commenting on the title Duchamp pointed out that there is a "dissociation gap" between sneezing at will and sneezing against one's will.
