1. The key

1. Insert the key into the cork at a 45° angle (serrated key to increase friction);

2. Slowly turn the key to drive the cork to rise slowly, and then pull it out by hand.

2. Screws and claw hammer

1. Take a screw (the longer the better, but try not to exceed the length of the cork) and screw it into the cork;

2. After the screw is screwed into the cork deeply enough, use the "claw" of the hammer to pull out the screw and the cork together.

Third, the pump

1. Use a sharp tool to drill a hole in the cork;

2. Insert the air pump into the hole;

3. Pump air into the wine bottle, and the gradually increasing air pressure will slowly push the cork out.
