    Is one of those "natural" inventions that has been around for millennia, rediscovered/reinvented and then used/discarded/dennied by countless generations of pubescent lads.

    So the real question is: why did it take mankind more than 10,000 years to figure out you could bottle the stuff, slap on a colorful label and sell it for a huge profit?

      until relatively recently.

      And what I'm talking about is the soap that you pour into the bottle and it looks like regular liquid soap.

      But somehow when it comes out, it has magically been transformed into foam.

      I've been thinking long and hard about this overnight, and now think that the magic must be in the nozzle/pumping mechanism - and not necessarily the soap itself.  So that should have been the technological advance I alluded to, not necessarily the soap itself.

      •  Actually, it is in the pumping action (2+ / 0-)

        Which vents air through a tube at the return valve.

        Some Japanese brands like KAO make incredibly small bubbles, it's like 10% soap.

        Take one to the hospital and use the MRI to make a tomograph, it will only cost you about $5000.
