The Air Table has a flat glass surface that supports the recording and carbon paper. Light surgical tubing supplies compressed air to the pucks. The air exits from the bottom of the puck, causing it to float over the recording paper. Spark recording marks the motion of the pucks. Fine metal chains run down the air tubes, providing a connection to the spark generator. The spark jumps from a contact in the center of the puck, leaving a mark on the recording paper. The spark gap is completely enclosed and cannot be seen or heard during operation. The spark source operates at 10, 15, 20, 30 and 60 Hz when used with 60 Hz line power.
