Since the touchdown of a tornado at Washington, IL in December 2013, my son has asked none stop about tornadoes and hurricanes.

Use two soft drink bottles and a connecting valve that you can purchase online or through Lakeshore Learning Store. Tornado Tube from Amazon.com
I bought this "ready" tornado without doing too much work of shaking a jar, and he can enjoy watching it whenever he feels like it. He eventually brought it to the kitchen table at meal times and to bed!
My son and I got all these books from the library!
