Info from Licensor: "My brother, my friend, and I went to San Francisco one October weekend to visit the Exploratorium. Outside that building is a free exhibit showing the scientific concept of parabolic shapes and sound waves. With one person on each chair, they can perfectly converse with each other at normal talking volume despite being super far away. SCIENCE!"
