This is why we should use the term "free-fall", instead of "zero-gravity". There is no way known to remove gravity. At best, you can cause the room to fall at the same rate as the things inside the room, causing the contents to float around. It's the same principle that allows specialized airplanes to create the sensation of weightlessness, while very-much in almost Earth-surface gravity.

>There is no way known to remove gravity Well, you can go far away from large masses to effectively diminish e.g. earth's gravity though, no? >It's the same principle that allows specialized airplanes to create the sensation of weightlessness, while very-much in almost Earth-surface gravity. Yes, but I was confused because space offers also regular diminished gravity, and we also have the example of the astronauts on the moon, where gravity was much much smaller. But I should have guessed that at the height ISS is it's too little to actually reduce gravity at any substantial way, and it's all the effect of the orbit/free fall.
