The Tornado Tube is a device made of molded plastic that can be used to connect two two-liter soda bottles. When one of the bottles is filled with liquid and the two bottles are connected with a Tornado Tube, they may be used as a children's educational toy demonstrating a vortex. [1]
Date: 1994 and 1995: Location: Tornado Alley: Also known as: Verification of the Origins of Rotation in Tornadoes Experiment 1: Outcome: Documented an entire tornado, which, in conjunction with deployment of the NEXRAD system, helped the National Weather Service to provide severe weather warnings with a thirteen-minute lead time, and reduce false alarms by ten percent.
The bottle is partly filled with water. Chunks of dry ice are added and the container is closed tightly. As the solid carbon dioxide warms, it sublimates to gas and the pressure in the bottle increases. Bombs typically rupture within 30 seconds to half an hour, dependent largely on the temperature of the air outside the bottle. [1]

Mariotte's bottle is a device that delivers a constant rate of flow from closed bottles or tanks. It is named after French physicist Edme Mariotte (1620-1684). A picture of a bottle with a gas inlet is shown in the works of Mariotte, [ 1 ] but this construction was made to show the effect of outside pressure on mercury level inside the bottle.
