Whirlwind in a Bottle DIY Science Project
Have you ever wondered how tornadoes form? With the Tornado in a Jar science experiment, you can create a mini tornado right at home! This simple yet captivating experiment is perfect for teaching children about forces and vortex formation using everyday items.
Materials Needed
To get started, gather the following materials:
- A clear glass or plastic jar (preferably with a wide mouth)
- Water (preferably warm to make swirling easier)
- Dish soap (a few drops)
- Optional: glitter or small lightweight particles to better visualize the vortex
Procedure
Follow these easy steps to perform the Tornado in a Jar experiment:
- Fill the jar about three-quarters full with water.
- Add a few drops of dish soap to help the water swirl smoothly.
- Add glitter if desired to make the vortex easier and more fun to see.
- Secure the lid tightly on the jar.
- Swirl the jar in a circular motion for several seconds, then hold it steady.
- Observe the spinning water forming a tornado-like vortex inside the jar.
Science Behind It
The vortex forms because of centripetal force, which pulls the water towards the center of the rotation, creating a spinning funnel shape known as a vortex. This mimics the physical dynamics of atmospheric tornadoes on a small scale.
Additional Experiments

Get Started Today
With the supplies likely already available in your kitchen, you can perform the Tornado in a Jar experiment right now. Fill the jar 3/4 of the way full with water, add a small squirt of dish soap, and put about a teaspoon of glitter inside. Secure the lid tightly, swirl the jar, and watch the magic happen!
The 'Tornado in a Jar' science experiment, which uses a clear jar, water, dish soap, and optional glitter, teaches children about centripetal force and vortex formation in an engaging and fun manner. This simple experiment, also known as a micro-tornado simulation, falls under the category of environmental-science as it helps to understand the physical dynamics of weather phenomena.
