Opening jars is easy in theory, but sometimes in practice somehow becomes a lot more difficult. Whether it was just someone really strong closing the lid or some residue around the edges sealing it closed, sometimes you need a little bit of extra leverage to get those jars open.
This is probably the easiest way to get a jar open if you are having trouble with it. Give it a try next time instead of asking someone else to try to open it for you.
If you are having a tricky time with it, there is one simple tool you can purchase at a dollar store to make it way easier.
Grab a pair of latex gloves. The rubbery texture will grip on the jar lids a lot better than your skin without hurting you!
So simple, so effective!
