This Is Perhaps The Best Approach For Opening Jars
There are a lot of other ways to open jars that have been tightly sealed, but this is probably the most effective one. Instead of trying to open the jar by slamming it on the table, which is unlikely to be successful and could result in the jar breaking, get a knife.
When you hear the lid make a small ‘pop’ and push it upward, it will be easy to open the jar. If you slide the knife into the lid of the jar and press it upward, it will open easily. However, you should be aware that this strategy does pose a threat to the egos of any emotionally vulnerable guys who might be in the vicinity.
