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.
Materials:
- glass or plastic jar with a lid
- liquid soap
- vinegar
- water
Instructions
1. Fill a jar almost to the rim with cold water
2. Add a few squire of clear liquid soap to the jar of water. The more the merrier.
3. Add a tad of vinegar to the jar as well. We added about a capful.
4. Put the lid back on the jar tightly and then first shake then swirl the jar to form a tornado!
