If you’ve ever been stuck without a can opener—especially at the worst possible time—this simple trick can save the day.

It might sound like something from a survival guide, but you really can open a can using just a spoon. And yes, it actually works—no fancy tools required.

Had we known this sooner, many of us could’ve avoided the hassle (and potential injury) of wrestling with knives or scissors just to get a can open.

The key is using a strong metal spoon—preferably stainless steel—on a standard can.

While it’s not as fast as a regular can opener, it’s perfect in a pinch when you don’t have one handy.

Here’s how: place the can on a flat, stable surface. Take the spoon and press its edge firmly against the lid where the seal is. Rub it back and forth quickly with steady pressure. In seconds, the metal will wear down and the spoon will break through.
