BVSA Rocket Bike

It may take NASA decades to finish construction on a shuttle, but it only took the Bay View Space Program a weekend to build its BVSA Rocket Bike. It was originally made so founder Jason Broemmel (who also built the Golden Gate Bridge Bike) could attempt to jump over Islais Creek in San Francisco for a bike rodeo. (He fell straight into the water.) The ride features rockets on either side that are powered by highway flares, illegal fireworks and propane. Broemmel's next project: a five-wheel bike capable of hauling two kegs of beer -- every astronaut's dream.
