I wonder how?

The sandman is changing when he goes into this pit of sand that has some glowing stuff underneathing it almost looks like rock you see that glowing rock stuff @ the beginning but as soon as sandman gets in there they turn on the fan just to 'blow him out 'assumingly like a tornado but instead of doing that & it looks like he's getting ripped apart by the fan wind in ways then it seems as if he got disolved so out he comes slowly appearing from the sand like as if human body print was thrown down there & so he can make his apperance look 'realistic ' but he just only has a body of sand -everything is sand.

i was thinking, the things were done by an animation software.
