If it's not CG. I can see how they "could " fake it.
It takes a bit of work, but for each picture they create the object/model in real life. Position it. And take the pictures. For the last picture they could have hanged it from the roof.
So just saying even if it's not CG remember it can still be faked the old fashioned way.
