Did you use Microsoft Air Simulator to do this?

You haven't answered my question.

OK, now wave your hand through a real fluid, I'd suggest water.

Did it feel the same as waving your hand through air?

If you look in books on aerodynamics, you'll find that air is effectively an
incompressible fluid at low speeds, such as those encountered in small
aircraft. It isn't until you get to the transonic range that compression
starts to be an issue, and the rules change substantially at and beyond the
speed of sound.
