Here is a trick I learned 35 years ago:
Here is a jar and a tool you can use.
Do you know what holds that lid so
tightly? It's the vacuum ladies, it's
the vacuum. If you let air into the
jar before you attempt to open it,
it opens like a breeze.
Tool used and jar to be opened.
Find the part of the lid that has a void
underneath. Get under it with the bottle
opener and gently pry up with your
other hand on the lid. When you allow
the air to enter, you'll feel the lid middle
rise. That means there is no longer a
vacuum. At this time you should be
able to easily twist off the lid.
This is another method, but be careful not
to bend the lid edge. You can also use a
standard silverware knife or a screwdriver.
Just put them under as before and twist.
What ever method you use, remember you
are prying against glass. So please be
careful. I hope this helps ladies.
