Don’t worry, this mini tornado is not powerful enough to blow you away. The swirling winds of a tornado are called a vertex. In this experiment, you can create a vortex that looks like a real tornado! The water in this experiment moves similarly to air in real life.
So, how does it work?
When you spin the bottle in a circular motion, you create a water vortex that looks like a mini tornado. The water spins around the center of the vortex very quickly because of the centripetal force. This fancy term means that an inward force is directing the water towards the center of its circular path. Tornadoes and hurricanes are both examples of vortexes that we see in nature.
