What is the last stage of a tornado?
This is called the “dissipating stage”, which often lasts no more than a few minutes, after which the tornado fizzles. During this stage the shape of the tornado is influenced by winds of the original storm, and can be blown into some amazing patterns.

Is the eye of a tornado calm?
Tornadoes are small-scale storms that produce the fastest winds on Earth. Single-vortex tornadoes (tornadoes that consist of a single column of air rotating around a center) are theorized to have a calm or nearly calm “eye,” an area of relatively low wind speed near the center of the vortex.
How does tornado kill you?

Can a funnel cloud turn into a tornado?
A funnel cloud is a tight rotating column of air (that is often the start of a tornado) that never reaches the ground. Storms can produce funnel clouds, but never produce a tornado. So a funnel cloud stays up in the sky, and it doesn’t become a tornado until it actually reaches the ground.
