Pop Champagne

Here is how you pop champagne:
Chill it well. The warmer the Champagne, the higher the chance it'll bubble over when opened.
Cut the foil. Instead of ripping it open, use the blade of your wine opener to score around the top of the rim by turning your hand—not the bottle.
Tilt the bottle. Hold the bottle at a 45-degree angle, away from you and others.
Push down on the cork. Hold the cork down firmly with one hand, and with the other, twist open the wire cage – it is five turns every time.
Twist the bottle, not the cork. With one hand still pushing down on the cork, slowly twist the bottle with the other hand. When the bottle opens, there should be a small cloud of gas and minimal noise.
