How the hell did they do that
I'm guessing if you pour liquid nitrogen over the metal ball, it'll become obvious.

Im assuming that would shrink it sufficiently is that your point? I wonder how many shatter getting it through if that's the case

That's what I'm assuming as well. Do metals get brittle when it's cold? I didn't really consider that. I assumed it would remain pretty malleable, but I guess I could be wrong.

Well usually if you pour nitrogen on anything it will become brittle. But Ive just thought about the possibility a little more and I think that maybe you've taken the wrong direction. When you freeze something it expands. Easy experiment to demonstrate this is to fill a glass to the brim and then place it in the freezer. It overflows because the molecular structure is less accomodating, causing the water to occupy a larger volume. Heat it on the other hand and it loosens up and allows the deformation that would be required. Heat it too far though and you will get plastic deformation which means the object wont return to its previous shape.

Actually I think I might be able to. The rubics cube was probabley taken apart, and reasembled inside the jar, the same with the scissors. The tennis ball was probebly flattened and crammed inside, and that golf ball looks small enough to fit inside the jar all on its own.

How would you assemble a pair of scissors in there? Or even the cubes?

It's the other way around - cold contracts, heat expands. Water is the only exception (or one of the few exceptions), and only within a certain temperature window, I understand.
