You wouldn’t be able to press a gas with your foot though.

I can imagine a scenario where you a gas is encased in a volume that you can reduce by stepping on it with your foot, thus pressurizing it.

Gasoline is a liquid.

Depends on what you mean by "press" really

Moving your foot through a gas will displace the gas, and there will be a (albiet small) pressure difference around the foot as it moves through the gas. An increase on the side in direction of movement, a decrease on the opposite side of direction of movement, and some vortices on the sides.

Basically a very poorly designed wing.

Mathematicians: "Always has been."

There's this Finnish joke that doesn't translate well, about a physicist who got pulled over by police. "Uh, I guess I accelerated a bit."

Tap for spoiler

(A particle accelerator is a machine that accelerates little bits. Do you get it now?)
