I'm not a flatard yet but heading that way. What does this video get wrong.

Also how does the earth transfer its 1000 mph spin up to the atmosphere? As the atmosphere gets thiner and at what point does the vacuum of space start to take effect?

There are two components to the motion of a bullet. The horizontal component and the vertical component. Gravity works on the vertical component and will cause the bullet to fall. Gravity does not affect the horizontal component, but air resistance will. The horizontal velocity of the bullet will go down as the bullet hits more air molecules along its flight. This horizontal velocity change, however, will not affect the vertical increase in velocity as gravity accelerates it towards the ground. There will be a small air resistance in the vertical component, which was what I was speaking of, that will slow the bullet's acceleration towards the ground. If the bullet were light enough, it could reach terminal velocity where the air resistance negates the increase in velocity due to acceleration. This is not much of a factor for our purposes though.

My explanation holds true, but you have to separate the horizontal velocity/deceleration from the vertical velocity/acceleration. I spoke only towards the vertical component, but I didn't make that clear.

Good explanation I can agree with except for this assertion which I find highly questionable.

Even if you had a bullet with the weight of helium it wouldn't work. Air resistance would have it floating like a soap bubble ten feet from your rifle. To overcome earth's gravity well and enter free fall orbit you must have a given speed regardless of mass.

Air resistance can cause low density objects to hit Terminal Velocity. Even a high mass object that has a shape that impedes air movement can hit terminal velocity. A large block of Styrofoam dropped from a tall building will not reach freefall velocity because it has too much drag as it falls. It won't stay buoyant like a soap bubble, but it also won't fall as quickly as a large rock from dropped the same height. In a vacuum, this is obviously not the case (feather and hammer).
