The reason why a sealed can cannot be opened is that the pressure on the outside of the can is higher than on the inside. If you want to open the lid, you have to balance the atmospheric pressure on the inside and outside of the tank.
1, can use a knife, scissors and other sharp objects, along the edge of the bottle cap to pry open, so that the inside and outside of the can atmospheric pressure balance
2.Use a stainless steel or brass spoon, key, paper towel wrap to add friction, and then pry the lid along the rim of the jar to let air into the can to open it.
3. Poke a hole in the lid with a sharp object or knife. Once the air is released, the pressure inside and outside of the bottle will be balanced and the bottle will open easily
Use your hot hair dryer at home to reheat the cap from far to near, and you will be sure to open the sealed jar
