This Hydraulophone is located outside the Ontario Science Centre. I would love to know more about how it works because it sure looks, and sounds, great. I wonder how they play it during those long Canadian winters? Hydraulophone video

Presently the world’s largest hydraulophone is the main architectural centerpiece out in front of the Ontario Science Centre, one of Canada’s landmark architecture sites. It is also Toronto’s only freely accessible aquatic play facility that runs 24 hours a day. (Wikipedia)

  1. As Steve Mann and company are academics, this project has been well documented in conference and journal papers. To get started, there’s the paper titled “Hydraulophone Design Considerations: Absement, Displacement, and Velocity-Sensitve Music Keyboard in which each key is a Water Jet” that includes diagrams and some of the relevant math.

    The paper presented at NIME 2007 (referenced on the Wikipedia page for your convenience) may also be of interest: “Natural Interfaces for Musical Expression: Physiphones as primordial Infra-Instruments”

  2. I took Steve Mann’s course at U of T last year. Really nice and interesting guy. This is just one of his neat inventions. His official site for it is . If you want anything else let me know!
