Always seeking new "thrills," I guess. Some guys up in Boulder CO came up with the idea of marketing caffiene-infused soap, so you could get your coffee jag on while taking your morning shower.
Don't know how that worked out, but I'm surprised nobody tried mixing pot with soap by now, since it's halfway (Statewise-only) legal now.
Just for grins and the sake of wisdom-seeking, I just mixed some club soda with half a cup of coffee.
Different, but not "better," and slightly worse. Slightly more bitter, I guess. Threw the half-and-half cup of reactants out.
Only a half-assed inconclusive experiment, and my taste buds are probably highly habituated to plain old strong coffee.
Science marches on.
