I'm not sure how to make water wetter than water except to dilute it with
some water. DOH!

I would speculate, however, that these 'Wetter' additives are, in fact,
surfactants. You might want to try  dishwashing detergent (make sure its
phosphate free, tho) ;-)

joking aside, IF (I'd have made that a bigger 'if' if I could have) you
believe these chemicals to be beneficial to your cooling capacity, Kodak
also makes a wetting agent that is _very_ cheap, commonly available at
photo stores, and is effective at reducing surface tension in fairly dilute
solutions (it goes a long way).
