20 Vortex Tubes:Classroom Set Create Cyclone - Tornado

 

You are buying a classroom kit of twenty Vortex tubes in four colors: red, blue, yellow and green. This is a great educational and fun experiment and activity for school classes, homeschoolers, scouts and any other group. Create a tornado from two 2 liter plastic bottles, water and a colorful plastic connecting tube. Swirling water creates a funnel-shaped vortex as it drains from one bottle to another. You can create different ways to work with it by timing the water draining, using bits of paper or food coloring or lamp oil. Go to http://www.exploratorium.edu/snacks/vortex.html to visit the The Exploratorium, www.exploratorium.edu to learn more about vortexes and this experiment. We also sell cyclone tubes individually that come with directions and scientific explanations.
