I am a 71 year old guy and I have to water heat the jar predominately jelly and leverage my weight to open sealed jars. Sorry Hillary and Jimmy that little jar stunt do ‘t hunt.
I’m a 77 year old male and often use a rubber ring grip to open jars.
I smack the jar lid on the counter, or whack the lid several times on its edge with a tablespoon. They open every time. I like violence, so that's what this 69 year old woman does.
I don’t know about the water heat jars but I hope they provided her with towels to sit on to save the furniture. I’d hate to have her leak all over the place.
Easy way we open tight jar lids:
We take a hammer and whack the lid in a handful of places. This releases the vacuum and it opens with ease (and closes again just fine).
The reason I don’t watch Kimmel anymore is beause he sides with every wacky liberal on the planet. Conservatives are his Kryptonite. You will never see a God fearing man on that show; just godless heathens who will conginue to support presidential candidates they know nothing about.
I turn the jar upside-down, and bang it on the counter. Works great.
If you use the tip of a spoon to pry under the edge of a jar lid, you can often break the vacuum and then the lid is easy to remove.
