Next time you open a bottle of soda or beer, take a look inside the bottle cap. Yeah, I know, there’s nothing to see. Just a soft vinyl seal. It wasn’t that way when I was a kid. Every bottle cap had a cork insert. And that presented possibilities. We used our jackknives to pry out the insert. In those days every guy had a jackknife. Mine had three blades. Some of the rich kids had super jackknives with scissors, screwdriver, and a corkscrew as well as three blades.
