What if the sealed jar can't be opened?

When making jam and curing some cooked food, we usually use sealed cans for storage. Sometimes we need to store it for several months to open it, but over time, our sealed pipes are not easy to open. What if the sealed jar can't be opened? Next, I'll give you some advice on how to open it.

Method 1:

We can pry it open along the edge of the bottle cap and use sharp things such as knives or scissors to keep the air pressure balance inside and outside the can.

Method 2:

Then we can wrap the paper towel with stainless steel and keys to increase friction, and then pry open the bottle cap along the edge of the bottle mouth to let air enter the can and open it.

Method 3:

We can find a sharp object or a knife and poke a hole in the lid. Once the bottle is deflated, the internal and external air pressure will be balanced and it will be easy to open.

Method 4:

We can turn the sealed can upside down, then grab the sealed can and pat the bottom of the can. Knocking on the lid can also break the intermolecular force between cans.

Method 5:

We can use the hot hair dryer at home to repeatedly heat the bottle cap or open the sealed jar from far to near.

Method 6:

I'd like to soak the sealed jar in a pot and heat it with hot water at 80℃ for half a minute, but be careful not to heat it for too long or you can pour the lid with hot water for a few minutes and then pull it hard to open it.
