Drive-in movies are nice, but they can't provide you with anywhere near the workout that the Cycle-in Cinema can. The Cycle-in Cinema is a pop-up movie theater created by the UK's Magnificent Revolution that runs solely off of pedal power.
The Cycle-in Cinema offers free film screenings to anyone with a bicycle and a willingness to pedal. Participants ride into the theater where there bicycles are then hooked up to a generator. Riders can use either their cellphones or a small radio to tune into the movie just like at a real drive-in. All riders are given a small meter that lets them see how much power they are producing with their pedaling. The Cycle-in Cinema could be a huge hit in the U.S. depending on which city you bring it to. Here's hoping Magnificent Revolution decides to bring their awesome idea across the pond sometime soon.
