This water thing is getting kinda funny. The loss of water from small plastic bottles is much more likely to be from the screw cap-bottle interface than by leakage through the plastic. It's just a hard plastic to hard plastic interface, with no soft gasket in there to completely fill the voids and make a more complete seal. That's the reason the large jugs hold their water for very long periods of time; they have a gasket under the cap. That's also the reason that you see full bottles of Coke at antique shops and flea markets... they have effective gaskets under the caps to hold the pressure and the contents. Let's move on from this water evaporation mystery??
