It simply creates a low pressure area and thus a pressure gradient. How the hell is a metal pipe gonna collapse? Ok. The pipe TENDS to collapse due to external atmospheric pressure. Happy? The vacuum FORCE is created by the MOTOR of the vacuum that you attached to the pipe. It actually exerts force on the gases within the pipe, but I simplified the explanation for the simple minded.

A force, created by burning the fuel pushes the gas away. The gas pushes back because it has mass. Not that you, lacking a capacity for abstract concepts, will be able to understand any of this. |
