What To Do If The Military Kettle Cannot Be Opened?

1. Wait for the water in the kettle to cool down. The military kettle has just been filled with hot water, and the steam rises, causing the air in the kettle to decrease and the pressure to increase, so it cannot be opened. Wait for the water to cool down a little before opening it.
2. Pat the bottom of the kettle. The lid of the kettle is sucked. Turn the cup upside down, pat the bottom of the kettle a few times, and then twist the lid to open it.
