Cyclone Tube Carded
Attach your tube to two 2-liter bottles and give it a swirl. Watch your vortex (tornado) spin in the bottle. 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. Instructions and scientific explanations are included. Cyclone tube is 2 inches long and comes packed in a nice blister pack on cardboard. Yours will be chosen at random from 4 colors (yellow, green, blue and red). This is a great educational and fun experiment and activity for school classes, homeschoolers, scouts and any other group.
