TORNADO/FOUNTAIN TUBE CONNECTION KIT
The Tornado/Fountain Tube Connection kit is a fun way for the young scientist to discover how a tornado or a fountain works. The kit includes two colorful connectors, tubing and instructions for each experiment. To create the tornado, fill one empty 2-liter soda bottle 2/3 full with water. Attach the connector to both bottles. With the bottle containing water on the top, begin swirling the bottles in a circular motion until you see a tornado funnel forming. To create the fountain, fill one empty 2-liter soda bottle 2/3 full with water. Attach the tubing and the connector to both bottles. The fountain will erupt every time you turn the bottle over.
