Hello all:  The discussion on disinfectants brings up a question that I have
been debating with myself.  Without much resolution.  To what extent are
tropical rains like a disinfectant wash?  My daughter has assured me that
distilled water acts as a disinfectant, killing thin membraned/skinned
parasitic creatures, osmotic pressure explodes them. Are tropical rains pure
enough to have this disinfectant quality? I assume dew is similar to distilled
water, however it does absorb surface particles that have not been washed
away. The absorption would reduce its purity.  But those great big tropical
drops, the ones that I have been hit in the eye with, when looking up in the
tropics are like a hydraulic eye wash. Could these drops be relatively pure?
Is it possible to create the same hydraulic pressure they deliver to the
surfaces they hit?

  The northern rains we have here do possess some cleansing ability, however
they are full of junk. Chemicals, various dust particles and tremendous
amounts of pollen during tree and weed pollinating cycles exist in the water
droplets.  You can also look up when it's raining.

    How does one create the tremendous surface cleaning/leaching/disinfecting
that the tropical rain potentially creates.
