Create a tornado in a bottle!
With this colorful plastic tube, learn about the science of vortex energy, the swirling, twisting and spiraling action that can be found everywhere in nature.

How does it work?

Fill one of the 1 or 2-liter bottles with water. Connect the empty bottle to the first with the Tornado Tube, so it looks like an hourglass. Tip this "hourglass" upside down, swirl the bottles, and in seconds a beautiful "tornado" appears.

What does it teach?

Use this experiment to introduce students to kinetic energy and potential energy. Help students discover how air pressure and density work together to create an incredible force of nature."

Bottles not included! Color will vary.
