Tornado Demonstration Machine
Want to experience the fury of a twister, but without all the death, destruction, and flat-out terror? The cool new Teaching Tornado Demonstration Machine generates a miniature swirling tornado that is not only fascinating and completely safe to witness, but also to learn from. Just add a little water to the base, turn on the atomizer to generate a cloud of fine mist, switch on the updraft fan on the top to draw it up, and adjust the six circulation manifolds on the sides to form the swirling funnel. It's not only way cooler than some boring old lava lamp, it can also be used in the classroom to teach students using seven different experiments. Either way, sit back, relax and enjoy the beauty of one of nature's deadliest forces - no terrifying tornado sirens or frantic searches for safe shelter needed.
