Help! Physics Project: Smoke Waterfall
1. The problem statement, all variables and given/known data
I have a presentation on our physics class and I have decided to demonstrate the phenomenon of Smoke Waterfall inside an airtight container. I saw my friend do this tons of times. It's really amazing but how can I explain the physics behind this trick? In general knowledge hot air is supposed to go up right? why is it the smoke coming out of the cigarette butt settle at the bottom? Help pls!
here's a video.
2. Relevant equations
3. The attempt at a solution

How much air is there in the container to begin with? Where does that air go when the smoke comes in? If you really don't know the physics why would you choose it as a presentation in a class?
Have you considered asking your friend?

And I guess out of curiosity too, I just want to know how this works.
thanks btw. your question made me think
