What to do if the sealed jar cannot be opened

In daily life, we often encounter such embarrassing situations that some sealed jars cannot be opened due to pressure. This is mainly because the air pressure outside is higher than that inside the jar. Therefore, it is often difficult to open. At this time, we should use some skills, which will make it more convenient to open. For example, you can blow the bottle cap with a hair dryer so that it can be opened smoothly.

Reasons why the sealed jar cannot be opened

The air pressure outside the jar is higher than that inside. If you want to open the lid, you must keep the atmospheric pressure inside and outside the storage jar balanced.

What to do if the sealed jar cannot be opened

1. You can use a sharp object such as a knife or scissors to pry open the bottle cap along the edge to keep the atmospheric pressure inside and outside the can balanced.

2. You can use a stainless steel, brass spoon or key, wrap it in paper towels to increase friction, then pry the bottle cap along the edge of the bottle mouth to allow air to enter the can, and then you can open it.

3. Find a sharp object or a knife to poke a hole in the lid. Once the air is released, the air pressure inside and outside the bottle is balanced and it will be easy to open.

4. Use a hot hair dryer at home to heat the bottle cap repeatedly from far to near, and you will be able to open the sealed can in the end.

5. Tilt the sealed jar upside down at a 45-degree angle, then hold the sealed jar tightly and tap the bottom of the jar, and the lid will open. The principle is to give the jar an impact, the sealed jar is stationary, but the lid part will continue to move due to inertia, in the direction of leaving the lid, so it will loosen. On the other hand, since the jar has been sealed for a long time, the intermolecular force makes it difficult to open the sealed jar lid. Knocking the lid also has the effect of breaking this intermolecular force.

6. Soak the sealed jar in a pot, then heat it with 80-degree hot water for half a minute (note that the heating time should not be too long), or you can pour hot water on the lid for a few minutes, then pull the lid hard and the lid can be opened.

After reading these 6 ways to open a sealed jar, have you opened the sealed jar? In order to prevent the sealed can from being unable to be opened, you should open the sealed can from time to time to allow the air pressure inside and outside to balance. I believe the above six methods can help you.
