Ready for some tornado action!? This is science at its exciting best, allowing a great visual demonstration of a tornado in a bottle. The valve joins two soft drink bottles together (not included) allowing you to create a swirling, twisting tornado. Use it to study properties of air as well as the atmospheric conditions needed to create a tornado vortex. This brightly coloured valve is great for any unit on weather or natural disasters.

Ages: 4 +

What you get

Plastic tornado connector. Colours vary. Plastic bottles not included.

How does it work?

Almost fill a one litre plastic bottle with water. Screw the tornado connector onto the almost filled bottle then attach the empty bottle to the other side (so it looks like an hour glass). Turn the bottles upside down, swish the water around and, presto, a cool tornado appears. This demonstration shows that air takes up space (or volume) and exerts a pressure. It also shows that when water flows down, air must move up. Add some food colouring to the water to get a different visual effect. Lots of fun!

FAQ

Any sized bottles will work, but one litre bottles are the best.
