A third tube passes through the dish A to the lower part of the globe B. This last tube being taken out, the globe B is partially filled with water, the tube is then replaced, and water is poured into the dish.

The air thus compressed acts on the water and makes it jet out as represented in the figure." — Hallock, 1905
