The correct way of opening a bottle of Champagne is
1. Remove the foil and loosen the wire cage, but do not remove the wire cage completely.
2. Put the bottle straight up on a table, and pull the cork out of the bottle.
3. Shake the bottle and allow the cork to pop out.
4. Grip the cork with one hand, and grip the bottom of the bottle with the other hand, and then turn the bottle.
