Does NASA have an anti-gravity room for training astronauts?

Yes, sort of. The room is on an airplane and they create anti-gravity by flying the plane in a big arc. You may have experienced something like this if you've ever been in a car going over a little hill or arched bridge. Your body wants to go in a straight line but the car is going up and then down, so it seems to you like your body is going up - or floating out of your seat - when the car starts going down. NASA does the same thing, but since they use an airplane they can make the "floating" last longer than just a few seconds - I think it lasts a few minutes. You might get a better answer if you ask your question in the physics section (hint: the force that causes your body to float when the car starts going down is called "inertia").
