Summarize this article in one sentence.
Use a kitchen knife to score the foil just below the lip of the wine bottle, then remove the foil cap and throw it away. Hold the bottle securely with your free hand, but keep it well clear of the knife tip and blade. Sit down on a steady chair and hold the wine bottle in a secure position between your legs. The top of the bottle should be pointing downward, while the base of the bottle should be pointing up. Grasp the bottle near its bottom (which is now facing upward) with one hand to hold it steady.

Summary:
Cut the cork foil with a knife tip and peel it away. Place the wine bottle upside down between your thighs.
