Vortex valve
The vortex valve is a designed to demonstrate how a tornado swirls. The vortex valve connects two large soft drink bottles.
With a flick of the wrist a tornado in a bottle is created. Scientific fun. Now supplied with two ‘0-ring’ seals to protect against leakage.
These fantastic connectors easily screw onto two plastic bottles. Begin by removing the labels from two empty fizzy drink bottles (preferably the same size) to provide a clear view of the tornado. Fill one of the bottles with water, about two-thirds full. Attach the second bottle to the first using the vortex valve connector. Initiate a circular swirling motion with the connected bottles, and then flip them around, ensuring the water-filled bottle is at the top. As you continue the circular motion, observe a tornado forming in the top bottle as water rushes through the valve connector.
For added fun, experiment with adding glitter or food colouring to create a visually captivating effect.
