I wouldn't mind knowing how they do that, then I'd make a small machine that just does that in my living room.

Yeah, I'm curious as well.

Did they do it mimicking how nature works, by pumping different temperatures in different places in the room, etc.?

What's with the lack of details?

Cool stuff.

The creator put some answers in the comments:

How the heck did i make it?

The living room of my father's place had a very strong ceiling fan, which could go in reverse. Instead of blowing air down, it would pull the air up. That would create an updraft strong enough to sustain the vortex. Next, I had a box fan and a blanket set up to redirect the air flow so it rotated around the center of the room. You can see it as the dark blue object in the back right. After the fans were turned on, I laid out an old dark red bed sheet with a small PVC pipe underneath it connected to a fog machine. The bed sheet allowed the fog to gently seep through and get pulled into the vortex, as opposed to being blasted out of the pipe. And then it was all a matter of letting the ceiling fan's updraft and the box fan's rotation mix into a 10 ft tall indoor tornado!!
