The bottle cap is too tight to unscrew and open the bottle.
You soak the bottle in hot water, and the water inside it expands. The pressure in the bottle rises and it turns off easily.
Roll the lid several times with a relatively heavy belt and screw it up.
Pick up can't unscrew the bottle upside down and then hit the bottom of the bottle several times, and then tighten the hand slap. Still can not open, at this time the whole bottle can be frozen in the refrigerator for a while, and then screw it, ok.
This is the bottle, who is still hot, you screw the lid too tightly, the water in the bottle is cool, the pressure in the bottle is reduced, and the bottle cap is sucked tightly.
