Once you get the lid off, layer plastic wrap over the jar before putting the lid back on. This will make twisting the lid off much easier next time you need to. [4] X Research source
Tapping the edge of the lid causes air bubbles to rise, loosening the seal of the lid. [6] X Research source
If you don’t have a source of constant hot water, you can make a hot water bath instead. Fill a large bowl with hot water. Then, invert a jar and plunge the entirety of the lid into the bath for a full minute. Take the jar off, dry it with a rag, then twist anti-clockwise with your dominant hand to open the lid.
You may need to smack the bottom of the jar several times to get the desired effect.
Do not tap the jar too hard. You can risk damaging the jar or even breaking it.
This heat, much like the hot water, expands the molecules making it easier to open. [11] X Research source Make sure to open the lid with a thick rag or gloves after heating it as you could accidentally burn yourself. Twist the lid counter-clockwise with your dominant hand.
