      Hi Hamza,

      By flying a plane up steeply and then plunging it back to Earth it is possible to remove gravity from the plane for about 20 seconds, the plane is known as The Vomit Comet for making people sick. NASA use it to practise weightless training on astronauts and also for research purposes. It is a very padded airplane!

      Without moving the room up and down like the plane, it wouldn’t be possible to create a room without gravity sadly, I do think that would be very cool.

      HI, James is right, a descending plane gives the illusion of zero gravity as you get put in free fall.
      Sadly we don’t have the ability to control gravity so can’t do that yet. But the force of gravity is related to mass of objects, so if you made a room with an incredibly dense ceiling then in theory you could make it counter earth’s gravity and you’d float. But you’d need a ceiling that was probably heavier than the planet. so a bit impossible
