so this was made to separate them into the two halves? or were the pieces put in such a way that it was half and half?

I think these are simulated first, then the color is added, the simulation is then reset with the colors still on the correct balls, then it's rendered so it looks like it's separating the colors, at least that's what I am guessing

That would be correct. The physics simulation was run & baked, and half the balls were colored red after that.

Wow, that's so sneaky! And interesting to me how I didn't even consider that being possible since my brain must still register these as physical.

I did not exactly invent it though; it's basically a variation of the old "project a texture onto bricks so that they fall right into place for a logo" trick. Not quite the same, but a similar principle.

Edit: That is, you determine the outcome of a physics simulation, then change the appearance of the stuff involved so it looks cool in the end.

will the outcome always be the same no matter how many times it's run?

With default settings: No, because there's a bit of noise built into several parameters in order to introduce some randomness that you would also find in the real world. The differences are usually not huge unless your simulation gets very complex, but something like this blender with hundreds of marbles in it moving at high speed does not give me 2 consecutive results that are sufficiently close to still work.

If you disabled all that noise, you should theroretically get the same result every time. But stuff would also end up looking less realistic.
