Amaze your friends and learn about gravity, air pressure and vacuums with this great hands-on science activity. This experiment, called Heron's Fountain, dates back to ancient Greece. The fountain defies gravity because water is draining down and spurting up at the same time!
The Soda Bottle Fountain Connector attaches to two 2-liter soda bottles (not included) and makes a fountain. Demonstrates partial vacuum and air compression. Add food coloring to the water for special effects. Use only with plastic bottles. Ages 6+ Made in USA.
