Notebooks of Scott

This is a Tornado Chamber I built for one of our Science Saturday workshops. Air enters the box through the two slits in the side and exits through the hole in the top. The positioning of the slits sets up a clockwise vortex inside the box (the rotation of the air in the box should be in the same direction as the blades of the fan). The window is made of some extra lamination film and allows a view into the box while still keeping air out. When the dry ice is put in the cup of hot water, it creates fog which subsequently follows the circular path of the air, thus creating the tornado.
