Q: How does a water organ work?
A: Water and air enter together into the camera aeolis (wind chamber). Here, they are separated and compressed air is driven into a wind-trunk on top of the camera aeolis to blow through the pipes. Two perforated ‘splash plates’ or ‘diaphragms’ stop any water spray from entering the pipes. The separated water then drives a water wheel which powers musical cylinders and movements attached to it.
