You might need to repeat this a few times to get the lid to loosen. You can try other kitchen utensils if you don’t have a kitchen spoon. Wood utensils work best, but anything heavy could work.
This method is called the “water hammer”. It functions by raising the pressure against the lid to pop the seal.
This method also helps to melt jam or other sticky foods that may have glued the lid shut in the first place. Be very careful with this method not to burn yourself. The metal lid will get very hot.
The hotter you get the lid, the more it will expand, but be very careful because both the lighter and the lid of the jar will get very hot!
It’s a good idea to try opening difficult jars over the sink or a counter. This way, it will be easy to clean up anything that spills out if the lid suddenly comes off quickly.
You can use a single glove if you feel like you have better grip on the body of the jar with your naked hand.
Note that the more clingy the plastic wrap, the more likely this method is to work.
You could try combining this method with the rubber band method by placing a rubber band over the dryer sheet to hold it more securely in place.
