Check out this video showing you how you can uncork a bottle of wine using nothing but a wall and your shoes (and it looks like something with a flat heel would work best). It’s really neat, although I’m not exactly sure in what situation you might want to crack open a bottle of wine but not have a corkscrew. It kinda seems like it’s designed for drinking on-the-go, haha. Whatever the situation, it’s certainly a handy maneuver.
