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.
