The St John Science Museum and Technotorium is going to build what we hope will be the World's Largest outdoor whispering gallery. Many famous whispering galleries exist in places like the U.S. Capitol Building. A whispering gallery allow an individual to hear what is being said in another part of the building because of the concentration of sound caused by the shape of the dome. Parabolic curves reflect the sound energy to a measurable focus point! See the video of the little gallery outside the Dallas Museum.
