Copernicus Vortex Device - A Portable Tornado Toy

Create and control a phenomenal vortex. Connect two bottles with the device and see this force of nature. Instructions included.

A vortex is a spinning, often turbulent, flow of fluid. Any spiral motion with closed streamlines is vortex flow. The motion of the fluid swirling rapidly around a center is called a vortex. The speed and rate of rotation of the fluid are greatest at the center and decrease progressively with distance from the center. When fluid is drawn down a plug-hole, one observes the phenomenon of a free vortex.

3. Connect the two bottles with the device.
