How can we create Micro-Gravity room ?

This is actually done by some researchers. They took a plane and after reaching sufficient height, the plane will be driven at an angle from the horizontal, towards the earth, with some acceleration. This acceleration should be such that the component of it, almost balances the gravity. This can be done only for few seconds. Hence the plane is driven in a curve, similar to that of sine wave, to get the micro-gravity situations repeatedly.





So the course of the plane is a series of take off and landing, in the midair.
