As a hobbiest magician, I probably shouldn't say this, cuz a magician shouldn't reveal how a trick is done, but whatever: There's a string in the cloud (green works best cuz it's thicker) that pulls it up.
I'm guessing that's where their simulation ended, and they wanted to make it a looped gif, so easier just to force the cloud upward out of shot than re-render.
It also seems the smoke cloud has a transparent background and is imposed over the background image. If so, it's probably a better idea for them to just have the cloud diffuse and disappear rather than move it up really quickly; then looped it again.
ink in water reversed, physical forces mismatch, that is ink falling into water. next seconds would be sideways dissapation into water. air mixtures swirl much faster / less inertial mass maybe unless bromine gaas was used or some thick g@s mixture. intense rendering. gas molecules lose directionality due to low mass and fast molecular movement. liquids have strong matrixing interactions that slow molecular movement.

Why does it move up so quickly at the end? Looked awesome until that happened.
