Tornado Tube Bottle Connector Cyclone Tube for Scientific Experiment Including 10 Tornado Connector (5 Random Colors)
How can you create a Tornado inside a bottle? Amaze your students with this visual demonstration.
Connect two bottles together, one filled with water. Turn the joined bottles upside down, swirl the water round and round, then watch what happens. Only a small amount of water flows into the lower bottle because of the reduced pressure above. By swirling the upper bottle in circles, water begins to pour again and a vortex is created.
