Weightlessness

Weightlessness is the experience (by people and objects) during freefall, of having no apparent weight. This condition is also known as microgravity (see below).

NASA's Zero-Gravity Research Facility

NASA's Zero-Gravity Research Labrotory is located at the Glenn Research Center in Cleveland, Ohio is a 145-meter vertical shaft, largely below the ground, with an integral vacuum drop chamber, in which an experiment vehicle can have a 5-second free fall, and then is decelerated at ca. 32g by pellets of expanded polystyrene. Alternatively, the vehicle starts at the bottom and is projected upward by a high-pressure pneumatic accelerator, after which it falls down again. Then the total duration of the weightlessness is 10 seconds.

Nearby there is also the 2.2 Second Drop Tower.

These are not for people, just for packages: the deceleration, and in the upward mode, also the acceleration, are too high, and the vehicle is too small.
