The first method: soak the bottle mouth in hot water for a while to make the plastic bottle cap swell, so it is easy to unscrew. It should be noted that only the bottle mouth can be partially immersed in water; If the whole bottle is made of plastic, put it in the refrigerator, because the bottle has a large internal area and a large space, which shrinks faster than the bottle cap and the ice will soon open.
The second method: choose the appropriate type of capping device according to the size of the bottle cap, 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.
The third method: gently pry open the edge of the bottle cap with a stainless steel spoon. When you are young, gas will enter and you can easily open the bottle.
