Demonstrate a vortex in your classroom! Some people refer to it as a tornado in a bottle. Show that in order for water to flow down, air must flow up. These amazing connectors screw onto two plastic soda bottles (you can buy new ones from E.I., Item number BOT-600 and allow students and teachers to create a water vortex. Or, connect two small soda bottles and make a sand timer. One of our all time favorites. Colors and styles may vary.
