1. Cleverly open the bottle cap with a capping device.
Methods: According to the size of the bottle cap, select the appropriate type of cap spinner and put the serrated part on the bottle cap. Just turn it by hand. Remarks: With this gadget, the bottle cap is easier to open because rubber can increase friction. Similarly, if you put on the rubber gloves for washing dishes at home and use them to open bottles, it is just as easy to use.
2. Gently pry open the bottle cap with a spoon.
Principle: Some large seasoning bottles are not easy to open even with bottle opener, which requires a little external force. Methods: Gently pry open the edge of the bottle cap with a stainless steel spoon. When you pry it open, the gas will enter when you are young, and you can easily open the bottle.
3, soaking in hot water is easy to open the bottle cap
When you encounter a bottle that is difficult to pry open with a spoon, you can try to pour boiling water into the bowl, soak the bottle mouth in hot water for a few seconds, and then unscrew the bottle cap. Usually, the bottle undergoes the principle of thermal expansion (the bottle cap will thermally expand one step earlier than the bottle), so the bottle cap that is difficult to open will be easy to open.
Step 4 increase friction
Sometimes we can't open the bottle cap because our hands are too slippery or the bottle cap is too slippery. We can put a piece of paper or a dry rag on the bottle cap to increase friction to open the bottle cap.
