Description
A "tornado tube" is formed by filling a bottle with water, inverting a second bottle over the first, and sealing them together at the mouths to form an hourglass-shaped device. When the tube is swirled and then flipped, water drains smoothly into the lower bottle while a standing vortex forms in the upper one.
