I believe it is nominally a hyperbolic paraboloid in shape�, so the parabolic cross=section would have a focal point. It suppose it*might* work if you covered one with aluminum foil and used it to collect and focus signals on a receiver, though my guess would be that a metal mixing bowl (or metal-lined plastic or ceramic bowl) would probably work better. _____ �Since fewer people today are as familiar with the shape of a horse saddle than earlier, some mathematicians and cosmologists use a Pringles� chip as a visual aid to show students what a two-dimensional surface of negative curvature might look like. If nothing else, you can bring a can to class and after discussing the concept, pass it around on the principle that students who are eating in class are at least awake . . . -- Ronn! :) Ronn Blankenship Instructor of Astronomy/Planetary Science University of Montevallo Montevallo, AL Disclaimer: Unless specifically stated otherwise, any opinions contained herein are the personal opinions of the author and do not represent the official position of the University of Montevallo.
