One tornado is reported to have had a damage path only seven feet long. It was likely on the ground for less than a second.

Despite its reputation, Wikipedia is a good site to go to. Websites connected to NOAA, such as the online tornado FAQ is also a good place to go. The Tornado History Project has a decent database of tornado records going back to 1950.
A good hypothesis for a science fair project using a tornado vortex (tornado in a bottle) could be: "If the speed of rotation is increased in a tornado vortex model, then the strength and duration of the vortex will also increase." This hypothesis can be tested by varying the speed at which the bottle is rotated and observing the resulting vortex's characteristics, such as its height, stability, and longevity.
A tornado watch is issued by the National Weather Service when weather conditions are favorable for tornadoes to develop. It means you should stay informed and be prepared to take action if a tornado warning is issued for your area. It is a warning for potential tornado development, not a guarantee that a tornado will occur.
