If you have ever tried to unscrew a tight metal lid on a jar, and you can't, you know what happens. Either someone else does it for you, or you tap it against the counter trying to loosen it up. Well, no more having to ask for help! If you just hold the lid of the jar under hot water for one minute, it should twist right off!
How is works: Most things expand as they get warmer. When the jar is heated up, the molecules inside it expand, causing lid to loosen. Since metal is a better conductor of heat than the glass jar, it heats up much faster , giving you the upper hand on removing that stubborn lid!
Let me know if you have any other tricks of your own!
