Why It Works
Jar lids are vacuum-sealed — the pressure difference between the inside and outside keeps the lid tightly closed. This hack works by expanding the metal lid just slightly, breaking the vacuum seal. When heated, metal expands faster than glass, so the lid loosens while the jar remains stable.
🔁 Step-by-Step Method
Step 1: Boil the Water
Bring enough water to a boil to fill a small bowl. You can do this on the stove or in an electric kettle — just be sure it’s hot enough to loosen metal.
Step 2: Place the Jar Upside Down in the Bowl
Flip the stubborn jar upside down and place just the lid portion in the hot water. Don’t fully submerge the jar — just enough for the water to cover the metal lid, not the label or contents.
🕒 Let it sit for 30 to 60 seconds.
The heat will cause the metal lid to expand slightly, which is often enough to release the vacuum seal.
Step 3: Carefully Remove the Jar
Use a towel or oven mitt to carefully lift the jar out of the bowl — the lid might be hot! Be cautious and dry the lid off with a towel if it’s slippery.
Step 4: Open the Lid with Ease
Now try twisting the lid — you’ll be amazed how easily it turns. No strain, no grunts, no slipping. Just a smooth twist and pop — the jar is open.
If it’s still tight, you can repeat the process for another 30 seconds.
✅ Extra Tips
For added grip, use a rubber glove or a piece of kitchen towel.
Don’t microwave jars with metal lids — always use boiled water instead.
This trick also works for jarred jams, sauces, nut butters, and honey.
