In "End Times" (Season 4 Episode 12) of Breaking Bad, there is a scene of Walt sitting near the pool. He places his gun on a table and spins it. The gun ends up pointing at him. He spins it again, and it points at him again. The third spin ends up with the gun pointing at a potted Lily of the Valley plant (awesome Chekhov Gun scene!). Here's the clip:
Now the spinning and the stopping of the gun are all done in one shot (the first two spins are both in one shot). So how did they manage to get the gun to point at the desired locations like that?
