If you ever find yourself in a survival situation where food is scarce, canned goods are going to be your best friend. There’s just one problem: canned good usually require can openers, and tools like that might be hard to come by in a post-apocalyptic wasteland (or the outdoors).

That’s exactly why it’s so important for everyone to learn important survival skills before they head out on a trip in the wilderness. Fortunately for your future self, there’s a simple technique to get just about any type of can open—and you won’t need any can openers to pull it off!

For decades, people across the globe have felt compelled to prepare for the very worst. Facing threats of nuclear war, zombie apocalypses, or simply a really bad storm, people have turned to fully stocked fallout shelters and bunkers in hopes of survival.

If you just so happen to find yourself in a survival scenario, food is obviously the most important factor, but it’s not easy to come by. That’s why canned foods have long been popular items to have on-hand in case of an emergency. There’s just one problem…

Canned food often requires a can opener, and that’s not always going to be as easy to locate. That’s why it’s important to know how to open a can without one. It might sound impossible, but rest assured—it’s not!

Thanks to YouTube user CrazyRussianHacker, you won’t ever have to worry about being stranded in an emergency with a can of food that you simply can’t open. Using his simple method, you’ll be noshing in no time! Here’s how it works…

All you need is two items. First, get your desired canned food. For this specific demonstration, the Russian Hacker uses tuna fish. The can is relatively small and it’s easier for him to demonstrate how the hack works.


Next, you’ll need a small piece of concrete. You don’t need to have a surface area much larger than a few inches. Now, grab your desired can of food and let’s get to opening it up!

The next step to opening your canned food item is to locate the top of the can and flip it over so it’s facing down on the slab of concrete. What’s about to happen next is practically magic…

Start to apply pressure to the side of the can that’s facing you—this will be the bottom of the can, essentially. Then, begin rubbing it back and forth on the concrete slab. Do this for several seconds; you’re essentially trying to wear down the can’s seal.

After that, pick up the can and flip it over so the worn side is now facing up. Next, wrap your hands around the outer rim. Be careful that you don’t cover the top of the can at all. (It’s sharp!)

Using your thumb and index finger, apply as much pressure as you can. This will allow you to loosen the metal seal that keeps the food inside of the can contained. Believe it or not, the lid will pop right off!

Didn’t think that would work, did you? It’s important to remember that survival scenarios mean more challenges than just opening canned goods. For example, in the event of a fire or gas leak, a simple bra can become a handy breathing mask. Virtually everything can have a second use if you think creatively about it…

Many more survival hacks can really come in handy if you’re stuck in a life-or-death situation. For instance, did you know that Fritos are actually flammable? Always carry a bag with you while hiking so you can make an impromptu fire. Just don’t eat them!

Have you ever needed to open a jar of food, but the lid became stuck? Luckily a stubborn jar is no match for a piece of duct tape. Just tear a strip—aim for about seven inches long—and stick one end of it to the lid. The rest should give you enough grip to twist it off!

You can even fashion a makeshift stove from two soup cans; make sure one is larger than the other. You’ll need a pocketknife to cut a hole in the big one; then, fit the smaller can inside. Light some tinder, and you’ll be ready to cook whatever you need!

If you’ve been hiking or rock climbing and you’re suffering from a minor cut with no Band-Aid in sight, fret not. Chapstick is your best friend! Not only will it help heal the cut, but it will also soothe the pain.

Another nifty trick most people don’t realize is that you can start a fire with two household items: batteries and steel wool. Just place them next to each other to create a spark.

Did you know you can turn condoms into instant water reservoirs? Since they’re made from sturdy, stretchy, and leak-free material, they can be used to easily store large amounts of fresh water. You’ll never have to worry about dehydration again!

You can also start a fire by using an old crayon. Since crayon wax acts similarly to a candle and it contains some combustible material, you can treat it the same way. Just burn a bunch using a lighter or a match.

If you’re stranded in the woods and happen to cut yourself but have no Band-Aids, you can make use of the leaves from a tree. This is a temporary solution, but it could stop the bleeding!

Who knew there were so many easy ways to survive in a dire situation? With all these techniques, you’ll never have to worry about being stuck in the outdoors ever again.
