The Unexpected Bar Gadget That Will Help You Open The Toughest Jars
BY CHLOE O'DONNELL
The next time you struggle to take the lid off a jar, reach for a bottle opener that hooks under the bottle cap. Then, wedge it under your jar lid, and tug gently.
You should hear a small pop as the air inside the jar is released. Afterward, you'll be able to twist open the lid with ease.
When a jar is sealed, the air pressure inside becomes lower than the air pressure outside. This creates a suction effect as the external air presses into the jar, sealing it closed.
Using a bottle opener breaks this seal, thus allowing you to open it more easily. If you try the bottle opener trick and the lid is still stuck, run the jar under warm water.
