There is no real such thing as a room without gravity, but you can create the illusion of zero gravity by accelerating downwards very quickly (i.e. in an aeroplane). This is one of the tests that they use for training astronauts!
In addition: there is now a gravity-free plane! It's the "Zero G" plane and simulates no gravity as it dives. It is still extremely expensive, but provides a "once-in-a-lifetime experience".
In free fall is should be gravity, obviously if an object is falling it should be gravity.
Gravity does not effect mass, weight is what you get when you resist the effects of gravity. (Note that in "free fall" and/or "micro gravity" you are not resisting.)
free fallThe term that describes motion that does not resistance to gravity is called free fall. This means that gravity does not caught you.
The acceleration in free fall IS the acceleration due to gravity, since "free fall" is the assumption that no forces other than gravity act on the object.
Gravity and free fall are similar because they are both a force that pulls objects downward. <><><><><> Gravity is the force that pulls you down. Free fall is when you have no opposing force keeping you up.
You raise a room very high in the sky with a helicopter, then get in, close the door and drop the room. Inside the rooms frame of reference you will experience zero gravity force acting upon you. Until the sudden stop at the ground of course. If you want a truly zero gravity room you must launch a room into space and send it infinitely far away from any other masses in the universe. Then of course the room itself will have a very small gravitational effect upon you so it won't technically be zero gravity. The truth is, zero gravity does not exist in the known universe, since the visible universe contains matter which has mass which leads to gravitation. Other than putting a room in a free fall frame of reference such as the falling room or in an orbiting space station there is no zero gravity room.
to buy a 0 gravity room would cost over millions
The gravity isn't any different, so it must be your talent at balancing is improving. :)
how does the gravity free water stay inside the cup
without gravity there can be no free fall. The only time humans have eperienced free fall is within a space craft where gravity is regulated.

Sorry, but earth is not a gravity free system. No matter where it is placed in the universe it will still have gravity that will affect all around it and that upon it.

gravity is the only force in free fall because free fall is when gravity is the only force acting upon an object
