Am I the only one who only saw a soup kettle fly up in a tower and then back down at falling speed. Where is the zero G.? cant they fire humans into the tower its like a moment of flying but not zero G still could be fun being launched in air.

What matters is that the objects and instruments they send up there are in zero-G relatively to each other, because everything is in free fall.

The force of gravity they're talking about here is the combination of gravity pulling you down and normal force of the object underneath you pushing you up, giving you that sensation of being pulled toward the ground. By evacuating all air and launching it, you practically eliminate all normal forces, removing the stress from the force of gravity and attaining the kind of conditions you'd have in space or orbit for a few seconds. If they were to not evacuate the air, the capsule would accelerate at different rates than what was inside of it because it's fighting against air resistance, making the results of the experiment inaccurate and the data not very useful.

Much like the planes designed to simulate zero-g environments, the environment and the objects within it are subject to gravity, but to the objects (or people in the case of the plane), the enclosed area acts as a reference to which we can see what it'd be like to be in a zero-g space, without air resistance effecting the actual test subjects.
that looks fun

Its fun until your blood vessels explode because you have no atmospheric pressure containing them

and also the drop causes you to turn into

Did anyone else find it extremely satisfying? that arc is beautiful
I really like how Tom Scott presents stuff.
Also, this experiment is insanely cool and practical.

This was Einstein's biggest insight, that except for tidal forces, an object in freefall feels the same as an object far away from any gravitating body. Freefall is zero-g.
