Open the screw jars
If I can not get a jar and my husband is not around, I take my scissors and open them.
With one side, I easily go under the lid between the lid and glass and press the scissors once against the glass until I hear a hiss.
I take a pair of scissors because it does not bend so easily because of its strength.
By this measure, the lid is not bent. Only the air pressure is reduced, which makes it easier to open the glass. Then you can still close the glass super.
