What to do if the glass can't be opened

We know that after filling a glass with water, if the water is cold, the glass may not be able to be opened at this time. This is a physical phenomenon caused by air pressure. When the glass cannot be opened, avoid using excessive force. You can use some tips to open the glass. For example, you can use a warm towel and put it on the lid of the glass bottle. This can have a certain effect of thermal expansion and contraction, thereby opening the glass.

1: Almost poked my hand by prying with a screwdriver. First, use the method of prying the bottle cap, pick up the screwdriver and pry the can cap. I pried it hard a few times and heard the glass at the mouth of the bottle breaking with a hissing sound. The screwdriver slipped and almost stabbed my hand. I stopped prying and then twisted the bottle cap hard, but it didn't open. Then I pried it open for the second time, this time changing 3 prying points, until I heard a "pop" and the can seemed to breathe a sigh of relief. I twisted the bottle cap again, and this time it came open without much effort. The whole process takes 50 seconds. Experimental experience: During the prying process, the screwdriver has a very small force point at the bottle mouth, so it is difficult to exert force. In addition, the screwdriver is easy to slip and it is easy to poke your hand if you are not careful. What to do if the glass bottle cap cannot be opened? 5 tips to help you deal with it easily

4: It is dangerous to roast bottle caps with open flame. It also uses the principle of "thermal expansion and contraction". If there is no hot water or container for hot water, some people think of using a lighter to heat the bottle cap. As soon as the lit lighter approaches the bottle, the bottle will make a "hissing" burning sound. Use a lighter to heat the bottle cap evenly. After about ten seconds, put a towel under it and try to twist the bottle cap, but it didn't work after several attempts. Then, repeat the above process, using a lighter to heat evenly for more than 30 seconds, and this time it was successful. The whole process took 1 minute and 12 seconds. Experimental experience: It is easy to burn your hands when roasting bottle caps with fire, which is quite dangerous. In addition, it is inconvenient to put a towel under it when twisting it. 5. The bottle cap hits the ground and the bottle mouth is easy to break. In the absence of any tools, in addition to patting the bottom of the bottle with your palm, there is another method that can be used, that is, knock the bottle cap on a hard surface a few times to achieve the purpose of "deflation" of the bottle. The reporter took a can and tapped it gently on the floor tiles. After that, he tried to twist the bottle cap with his hands, but failed. Afterwards, the reporter increased the force and knocked it a few more times. After knocking it, he twisted the bottle cap and repeated it three times before opening the bottle cap, which took one minute.
