This is a hybrid motor - nitrous oxide is the oxidizer. The ignitor starts the tar burning and nitrous oxide is injected to sustain the reaction. My hobby is high powered rocketry. You can use anything from a polyethylene rod, compressed newspaper, or literally, a pepperoni sausage No kidding with the latter, it's been done!

Heh, it was invented by a russian scientist for the KGB in the early 70s. i spoke to the guy while working for Popular Mechanics/Russia. He was selling a modification for pulbic health (it's essentially a miltiple-sensor vital stats detector). Anyway, the technology is inferior to modern detectors which monitor brain activity via MRI.

While this is correct, it is somewhat misleading, as the tar needs to be mixed with an oxidizer for it to combust fast enough for meaningful thrust. The technically challenging part of mixing a tar rocket is stabilizing the oxidizer: perchorate. The “rocketbike” article mentions that the rocket engine uses roofing tar as fuel.
