Create a tornado in a bottle! This exciting experiment is a hands-on demonstration of "vortex action". Use this experiment to study kinetic and potential energy as well as the atmospheric conditions needed to create a tornado vortex. Introduce students to a fascinating weather event with this experiment. Kids can learn about the difference between kinetic and potential energy, and the atmospheric conditions that tornados require. The vortex action allows an interactive experiment that creates a tornado in a bottle. Details:5.8" x 3" x 1.8"Vortex action creates a tornado in a bottleFor ages 5+Pack of 8
