Fart powered missile launcher

The patent office is full of it isn’t it?

To operate the assembly, the operator places the inlet tube with its valve open adjacent his anal region from which a colonic gas is discharged. The piston is then withdrawn to a degree producing a negative pressure to inhale the gas into the combustion chamber to intermix with the air therein to create a combustible mixture. The ignitor is then activated to explode the mixture in the chamber and fire the missile into space.

I had no idea that flatus could be used in such a manner. Could you imagine if Nerf picked up on this?
