The air-cushion table possesses a flat glass surface serving as a base for recording paper and carbon paper. Compressed air is supplied to the pucks via light hoses. The air emerges from the bottom of the pucks, making them hover over the recording paper.
The motion of the pucks is traced by means of spark recording. The air hoses contain thin metal chains via which a connection to the spark generator is established. The sparks jump over from a contact in the center of the puck, leaving marks on the recording paper.
As the pucks weigh 550 grams, their motion is not affected by the hoses or the attached spark wire.
