Duchamp regarded chance as a means 'to combat logical reality'. This work was made by dropping three threads, each a metre long, from a height equal to their length, then cutting wooden rulers to record the shape in which each had fallen. Duchamp described these as
'a preserved metre, preserved chance'. He later used the templates in his composition on glass The Bride Stripped Bare by her Bachelors, Even (The Large Glass) to draw the capillary tubes connected to the nine Bachelors' heads.
