1. Screw-opening method: Drive part of the screw into the cork and leave the other part outside. Use pliers to tighten the screw and pull out with the cork.

2. Knife bottle opening method: Use a fruit knife or a serrated knife. The blade should not be too wide or too narrow, just enough to dig into the cork without cutting the edge of the cork. Drive the blade into the center of the cork, trying to avoid scratching the edges. Hold the bottle neck with one hand and slowly turn the handle to drive the cork to turn together; the force should not be too strong when turning. Then slowly lift the handle upwards and slowly pull out the cork.

3. Paper clip bottle opening method: Take two paper clips and a pen. Partially straighten the paper clip, keeping the curvature at the ends the same. Insert two paper clips into the bottle through the gap between the cork and the bottle mouth until the end of the paper clip is lower than the cork. Twist the paper clip to hook the cork. Wrap the other end of the paper clip securely, insert the pen into the wrap, pull up, and slowly pull out the cork.
