I was cleaning out the water reservoir of my CPAP machine with alcohol tonight—the water is heated to humidify the air so that one's insides don't dry out overnight—and reflecting on the alcohol I was using, namely Everclear. Everclear is the brand name of an azeotrope of 95% ethanol and 5% water. I like to use it to clean stuff that I might eat or breathe since it's a relatively safe organic solvent in trace amounts. Sadly, because Everclear is booze, it's crazily expensive, heavily regulated, and actually banned in some states. (I'm not sure why a 50% mixture is legal and a 95% aezotrope banned, but there you are.) In particular, we really can't have it in our lab at work, where it would be quite useful sometimes.
No real point here; just sayin'. (B)
