Experience a rocket car with your imagination or watch this low-quality, silent video featuring the X-12 model: http://www.youtube.com/watch?v=tcA4KHZOLG4. The X-12B uses similar fuel and had a successful launch, as seen in another video: http://www.youtube.com/watch?v=TIAwVWGTbzU. Although not visually impressive, it was entertaining. Consider adding wheels to the design for improved functionality, along with a high-density, infill solidity.
