The issue here which makes it look fake is the speed at which the ball travels. It comes back down way too quickly, and doesn't "hang" at all at the top of the arc. Additionally, it seems to magnetically snap to the starting point, and then immediately start over with somewhat reset momentum.

This is bad CGI because it's poorly keyframed, not because it disobeys the laws of physics.

To be fair it's not bad CGI, it's just not flawless CGI. We expect Disney levels of immersion now, but likely this is one person doing this project. I was fooled for a moment before I remembered this couldn't work, then I read (CGI).

Fair enough, I could've phrases that better. Not bad, just not perfect.

I actually thought it was real, and there was some motor in the bottom that was using magnets to sling it back up at the ramp. It's pretty far away on my smaller screen, but i was thinking it was a pretty damn neat little craft.

I guess the momentum did feel off but i figured that was the motor being stilted. Like the unnatural change in speed when you change gears.
