Two 2 liter bottles plus one Tornado Tube equals one tornado in a bottle!
Fill one bottle with water. Connect two bottles with the Tornado Tube so it looks like an hourglass. Tip it upside down, swirl the bottles, and in seconds a “tornado” appears! Use this experiment to study kinetic and potential energy, as well as the atmospheric conditions needed to create a tornado vortex. This colorful plastic tube experiment is a great introduction to any weather unit.
Help kids discover how air pressure and density work together to create an incredible force of nature. Learn about the science of vortex energy, the swirling, twisting, and spiraling action that can be found everywhere in nature.
Great for hands on demonstrations. Add food coloring for greater visual effect!
Contains: one Tornado Tube - assorted colors. (Bottles not included.)
