Opening cans is a common problem, but many people experience difficulties in unscrewing them. Here are some tips and tricks for opening cans:
Open the can using the principle of thermal expansion and contraction: prepare a bowl first, then pour hot water. Then place the can upside down, let the hot water cover the can, and let it soak for 30 seconds. When the time is up, take out the can and twist it slightly, and it will be opened. This method also has the advantage that no matter how big the bottle is, as long as you put it head down and soak it in hot water, no matter how difficult the can is, even if the strength is small, it can be easily opened.
Use a can opener: If you don't have one, you can use some small tools, such as keys, fingernails, pens, etc., to pry the metal lid on the top of the can open.
Use a hammer or heel to tap the top of the can: Gently tap the metal lid on the top of the can to loosen it, then twist it gently to open.
Use lemon juice or vinegar to soften the can: Pour the can into the lemon juice or vinegar, steep for a few minutes, then take it out and open it with a slight twist.
The above are some tips and methods for opening cans, I hope it will help you.
