This cool vortex valve tornado tube is designed to demonstrate how a tornado is created.
Simply choose two large soft drink bottles of the same size, fill one with water, then connect them together with the special Tornado Tube Vortex Valve. With a flick of the wrist you'll create a tornado in a bottle!
It's great scientific fun. Add food colouring to the water for an even cooler effect!
