A hydraulophone is a water-based musical instrument that is played by pressing fingers against water jets to force water through or against an array of underwater whistles or similar sound-producing devices.
The world's largest hydraulophone is a large fountain that is the main centerpiece out in front of the Ontario Science Centre in Toronto, Ontario, Canada. It runs 24 hours a day so that anyone can play on it anytime.
