One of my 2nd graders was mesmerized by the foaming action of the newest soap dispenser from Johnson&Johnson; press the pump and foam surges out the spout and into your hand. I *thought* I could explain it quickly but even after we tore the spout apart, it defied our attempts.Would there be someone here that understands how the soap is processed into foam without water being added and rubbing your hands together? Diagrams that I might blow up and use to explain the process are _always_ appreciated!The Ranger

It is probably more complicated than a simple venturi system, but I pretty sure that is the basic operation of it.
