This was a project I did a while back its pretty easy. All's you need is two bottles and water and tape. This got me a second place ribbon so it not a bad project. It was also very easy to conduct.
Comments for Tornado in a bottle.

Maybe modelling air pollution will get you the answers you need for this problem.
That's what I do full-time. Try it.
