These amazing connectors screw onto two plastic soda bottles (you can buy new ones from E.I., Item number 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. Helpful tip: When the cap is removed from a soda bottle it often leaves behind a jagged "security ring". To ensure the best seal, cut off this ring before using our bottle connectors.
