The Teaching Tornado by American Educational Products is an 18-inch-tall desktop storm simulator that creates a tornado-like swirling air vortex using an atomizer and a fan. Recommended for grades 5th through 9th, the system features adjustable air circulation direction and updraft and intake speeds to demonstrate the role each play in the creation of a tornado funnel. The Teaching Tornado is available for purchase through Hammacher Schlemmer and Amazon.
