What should I do if the double-layer glass cannot be opened?

Under normal circumstances, the bottle cap cannot be opened, because the hot water has been placed for a long time after being poured in. Sometimes I'm worried about leaks so I screw the cap a little tight and it won't open. This phenomenon is caused by stress. In order to prevent this from happening: (1) Fill the cup with water close to room temperature; (2) Do not overtighten the lid of the cup to ensure no water leakage. Well, sometimes the lid won't open. What should I do at this time?

What should I do if the glass cannot be opened when drinking water?

1. Shake the water glass vigorously, and then basically open the lid;

2. Put the quilt in warm water for a while, then turn it on. Remember not to let the water temperature be too high, so as not to break the water glass;

3. Turn the cup upside down, tap the bottom of the cup, and unscrew the lid.
