In "Car-E-Oke," you can choose the make and model of a car and sing along to its exhaust sounds. Regular engine noises have fun karaoke subtitles. But there's a catch: the sound system is bike-powered. Visitors are encouraged to hop on the bike and "pedal-power" the PA. In addition, I bike every other day of the exhibition, wearing bike shorts, a sequined top, shiny sunglasses, and a fanny pack that emitted sound tracks from classic car chase movies.
