This is a hands-on demonstration of vortex action.
Children use the experiment to study kinetic and potential energy, as well as the atmospheric conditions needed to create a tornado vortex. Create a tornado in a bottle!
A simple device connects two plastic bottles and suddenly your students are discovering a whirling vortex of air and water!
The ingenious design of a simple piece of tubular plastic opens a world of thought-provoking possibilities for your class.
The Twister Tube connects two plastic bottles in such a way that when water is added and the bottles are swirled, a vortex of water and air is created. The experiment is simple, but the possibilities are endless. Your students can use this device to hypothesize, observe, measure, experiment, and discover.
Great science fair experiment!
