- 1 Jar
- 3 cups of water
- 1 teaspoon of dish soap
- 1 teaspoon of vinegar
- Optional – glitter, small objects, food coloring, etc
- Flat surface
- Fill the jar with water. Make sure to leave an inch of space at the top.
- Pour the dish soap into the water.
- Pour the vinegar into the water.
- Close the lid of the jar. Double check that it’s screwed on tightly!
- Place one hand on top of the jar and one on the bottom of the jar.
- When your hands are in position, swirl the jar for five seconds.
- Then, set it down on a flat surface and watch your very own tornado in a jar!
When you are doing this experiment, you create a vortex by spinning the jar of water. A vortex is the motion of the fluid swirling rapidly around a center. As you swirl the jar, centripetal force causes the spinning water to surround the vortex, making a mini tornado! If you would like to learn more about tornadoes and how they form, watch the video below!
