Truly to open 1st zero-gravity hard seltzer bar aboard astronaut training aircraft

Yes, most people just watch the ISS crews on TV and think of weightlessness as swimming in air instead of water - and then are surprised that it feels more like falling continuously - because that is what it is, really.

When swimming in water, your inner ear still tells you which way is up. And, the contents of your stomach have a "down".

But, what gets really interesting is when it is time to use the toilet. At least the parabolic flight paths are not long enough to require that experience.
