Tornado Tube

Create a spinning vortex and explore real-world weather science with the Tornado Tube, a hands-on STEM tool that transforms two standard 2-liter bottles into a powerful tornado demonstration.

• Demonstrates vortex motion and rotational flow through visual experimentation
• Helps students explore weather science, fluid dynamics, and cause-and-effect
• Easy to use—connects two standard 2-liter soda bottles (not included)
• Encourages prediction, observation, and scientific discussion
• Ideal for classroom demonstrations, science centers, and STEM labs
• Durable design for repeated use in educational settings
• Includes complete instructions for setup and experiments

To use, simply attach the Tornado Tube between two filled 2-liter bottles, flip, and swirl to create a fast-spinning water vortex that mimics the motion of a real tornado. Students can experiment with speed, direction, and water levels to observe how vortices form and change.

Perfect for upper elementary classrooms, homeschool science, and hands-on learning environments. Recommended for ages 8+—an engaging, low-cost way to bring weather and physics concepts to life.
