We just had a pot lid (cooking stew on the stove) get totally stuck. From a vacuum that formed.
Ended up having to pry it loose with a screwdriver. But is there some other way?
I found these suggestions on-line. It is interesting to me, though, to look to the internet immediately for answers, and not to a book on the shelf! Really, books are becoming less useful, as long as a high-speed connection is up and running all the time.
Also replacing books, I got a Kindle from Amazon about a week ago. I do like it, and have several books, magazines, and newspapers there already. I think the big advantage is that it takes up so little space. And, you can adjust the font size.
But still, the physicality of books has a great appeal for me. (And my mom was a librarian!) But I guess the internet is really taking over as our information source.
