Tornado in a bottle.

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.
All's you have to do it shake it and explain whats happening and put down your observation on whats happening in the bottle. To put it together just fill 1 bottle 3/4 full then put the other bottle upside down on the other one and tape it securely. So no matter what grade you are in this is an easy project to do and get an OK place (2).
Barry's Response - Right, especially if you make an honest-to-goodness attempt at explaining what is happening with the liquid. I'll bet it was fun. Thanks, Annette.
