Picture of This Old Tornado
Description of how to build a tornado model. This instructable is faster paced as an old model tornado prototype is restored and operated. This design is by no means bomb proof and should only be operated under close supervision.

Step 1: Parts of the Tornado Model

In this step, plans for the foam insulation and chamber windows are given.
Thank you for the post! It looks like you rely on the lamp to generate heat and the motion of the fog entering the chamber at an angle to generate the tornado, is that correct? What does the fan do, then, if the lamp is the primary tornado generator? Does the fan assist the turbulence further?

great instructable and very similar to my tornado machine. if you used better materials like wood and painted it you could have a good lookin tornado machine.

I'm sure your design would hold up much better than this prototype. The science museum where I used this design eventually bought a permanent commercial tornado exhibit.
