1. Using a vise, clamp the lid and turn it along the edge of the lid, thus unscrewing the cap.
2. Using an iron spoon, insert the handle of the spoon into the gap between the lid and the bottle, and forcefully cock it so that the air enters the can and balances the pressure on both sides of the lid, thus opening the lid.
3. Quickly heat the bottle cap so that there is a gap between it and the bottle to open it.
4. Flip the bottle over, with the lid face down, and tap the bottom of the bottle for a little while longer, so that the lid can loosen a little, thus trying to open the lid.
The above methods are for reference only, you can choose the appropriate method according to the actual situation. If the cap is too tight, we recommend you use other methods or seek professional help to avoid injuries caused by excessive force.
