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 experiment became a subject of the television show MythBusters in 2006. [ 13 ] [ 15 ] Spangler signed a licensing agreement with Perfetti Van Melle , the maker of Mentos, after inventing an apparatus aimed to make it easier to drop the Mentos into the bottle and produce a large soda geyser.

Weather modification is the act of intentionally manipulating or altering the weather.The most common form of weather modification is cloud seeding, which increases rainfall or snowfall, usually for the purpose of increasing the local water supply. [1]
if fixed, undisturbed, in free air, not exposed to radiation, fire, or sun, but in the ordinary light of a well-ventilated room or outer air, the chemical mixture in a so-called storm-glass varies in character with the direction of the wind, not its force, specially (though it may so vary in appearance only) from another cause, electrical tension.
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.
[6] [1] The experiment attempts to assess the subject's spatial reasoning. The subject is shown an upright bottle or glass with a water level marked, then shown pictures of the container tilted at different angles without the level marked and asked to mark where the water level would be.
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]
