A jar of water with a little vinegar and liquid soap added can be transformed into a Tornado-science lesson with this cool activity! A tornado is a violent rotating column of air that forms under the right weather conditions. When a tornado forms it creates a vortex which is a spinning, often turbulent flow of air. We can create our own vortex by swirling the contents of the jar (soap and water plus a little vinegar) to observe the motion of a tornado. Explore the science behind tornadoes with this easy activity and open up a discussion with your kids.
