LOx spilled on asphalt can be explosive. Lose a foot explosive. We always moved LOx while on clean concrete or dirt surfaces at the rocket company. It doesn't take too much looking to find a video on YouTube of a diamond burning in a test tube of liquid Oxygen. Granted, diamond is pure carbon, but still....
The Mythbusters once tried to make a rocket motor from a sausage and NOx. They got stymied by the structural strength of sausage as the exhaust velocity would always push the bits of meat out of the motor casing. Sugar can be used as a rocket fuel. Sugar Shot to Space has been working on perfecting a sugar motor for a few years (small hobby group).
LOx is very dangerous.
