Making Tornado In A Glass

A tornado, also called twister or cyclone, is a violent rotating column of air extending between the Earth’s surface and the base of a thunderstorm. This vortex of wind, usually funnel-shaped, can be very destructive. It can destroy large buildings, uproot trees, drive sticks into trees and hurl cars hundreds of yards away.

But in this experiment, we will make a water tornado safely at home. Let’s see how a rotating vortex is formed.

What you need

• a tall glass or jar (lid is good but optional)
