How to Open a Can Without Any Tools

How to Open a Can Without Any Tools

A recurring theme in the nightmares of many preppers and zombie apocalypse aficionados is a scenario in which survivors hunker down in their bunkers, surrounded by cans of food that should help them wait out the storm, only to realize that they’ve forgotten to pack a can opener. Quite a frightening thought, isn’t it? Well, it doesn’t have to be—there’s an easy way to open a can without any handy little implements, and the only thing you need in order to do so is a material that’s found all over the world:

Concrete.

If you have any canned goods in the house, take a quick look at the cans’ tops for a second. You’ll notice that there are two edges that have been sealed together in order to keep the contents fresh and edible, which is why people generally use a can opener or other sharp blade to pierce through to the tasty contents within.

To get to the delicious niblets inside those cans without any tools, you need to break through that bonded seal, and that can easily be done by rubbing the top of the can over a concrete surface. The way this works is quite simple: if you’ve ever fallen on concrete, you might have ended up with scraped knees, elbows, hands, etc. Why is this? Because concrete generally has a rough texture that is as ideal for opening cans as it is unkind to skin surfaces.

Opening the Can

To open your can, place it top-side down onto a piece of concrete. This could be a cinder block, a sidewalk, or any other cement surface that happens to be nearby.

Place the palm of your hand on the bottom of the can, apply a fair bit of pressure to it, and then scrape the can back and forth across the concrete surface. Doing so will wear away the seal on your can, but be patient—it’s better to take your time and wear it down slowly than to scrape it too hard, too quickly. You don’t want to end up forcing the seal open and getting concrete dust and grit in your food.

Once you’ve worn away the seal, all you have to do is squeeze the sides of the can gently and the top should just pop open. If it doesn’t, scrape away at it a little bit more and then try again. I know this sounds almost too simple to be true, but I’ve tried it myself and it does actually work.

Be careful after popping the edges apart as they may have been sharpened by the friction and you probably don’t want to slice your hand open. In situations where you may not have immediate access to medical supplies, getting tuna juice or beef stew into an open cut is an invitation for some nasty infections. Let’s consider this a reminder to ensure that you always have a basic first aid kit in the house: not only can you patch yourself up with its contents, but you can use an alcohol swab to clean off your concrete surface if any canned goods spill out over it. Keeping things as clean as possible will lessen the chance of illness from rotting food particles and cross-contamination.

If you’re having difficulty visualizing how this could work at all, check out this video. In it, a couple of terribly cool Russian guys (they call themselves “Crazy Russian Hackers”) give a demonstration on this very technique.

Just think of all the people in zombie films and Cold War shelters who could have benefited from knowledge of this technique! Talk about a true life-hack. Although some people may laugh off this technique as being ridiculous or extreme, you really never know when you might be in a situation where it might come in handy.

The 10 Essential Habits of Positive People

The 10 Essential Habits of Positive People

Are you waiting for life events to turn out the way you want so that you can feel more positive about your life? Do you find yourself having pre-conditions to your sense of well-being, thinking that certain things must happen for you to be happier? Do you think there is no way that your life stresses can make you anything other than “stressed out” and that other people just don’t understand?  If your answer is “yes” to any of these questions, you might find yourself lingering in the land of negativity for too long!

The following are some tips to keep positive no matter what comes your way. This post will help you stop looking for what psychologists call “positivity” in all the wrong places!  Here are the ten essential habits of positive people.

1. Positive people don’t confuse quitting with letting go.

Instead of hanging on to ideas, beliefs, and even people that are no longer healthy for them, they trust their judgement to let go of negative forces in their lives.  Especially in terms of relationships, they subscribe to The Relationship Prayer which goes:

 I will grant myself the ability to trust the healthy people in my life … 

To set limits with, or let go of, the negative ones … 

And to have the wisdom to know the DIFFERENCE!

 2.  Positive people don’t just have a good day – they make a good day.

Waiting, hoping and wishing seldom have a place in the vocabulary of positive individuals. Rather, they use strong words that are pro-active and not reactive. Passivity leads to a lack of involvement, while positive people get very involved in constructing their lives. They work to make changes to feel better in tough times rather than wish their feelings away.

3. For the positive person, the past stays in the past.

Good and bad memories alike stay where they belong – in the past where they happened. They don’t spend much time pining for the good ol’ days because they are too busy making new memories now. The negative pulls from the past are used not for self-flagellation or unproductive regret, but rather productive regret where they use lessons learned as stepping stones towards a better future.

4. Show me a positive person and I can show you a grateful person.

The most positive people are the most grateful people.  They do not focus on the potholes of their lives.  They focus on the pot of gold that awaits them every day, with new smells, sights, feelings and experiences.  They see life as a treasure chest full of wonder.

5. Rather than being stuck in their limitations, positive people are energized by their possibilities.

Optimistic people focus on what they can do, not what they can’t do.  They are not fooled to think that there is a perfect solution to every problem, and are confident that there are many solutions and possibilities.  They are not afraid to attempt new solutions to old problems, rather than spin their wheels expecting things to be different this time.  They refuse to be like Charlie Brown expecting that this time Lucy will not pull the football from him!

6. Positive people do not let their fears interfere with their lives!

Positive people have observed that those who are defined and pulled back by their fears never really truly live a full life. While proceeding with appropriate caution, they do not let fear keep them from trying new things. They realize that even failures are necessary steps for a successful life. They have confidence that they can get back up when they are knocked down by life events or their own mistakes, due to a strong belief in their personal resilience.

7. Positive people smile a lot!

When you feel positive on the inside it is like you are smiling from within, and these smiles are contagious. Furthermore, the more others are with positive people, the more they tend to smile too! They see the lightness in life, and have a sense of humor even when it is about themselves. Positive people have a high degree of self-respect, but refuse to take themselves too seriously!

8. People who are positive are great communicators.

They realize that assertive, confident communication is the only way to connect with others in everyday life.  They avoid judgmental, angry interchanges, and do not let someone else’s blow up give them a reason to react in kind. Rather, they express themselves with tact and finesse.  They also refuse to be non-assertive and let people push them around. They refuse to own problems that belong to someone else.

9. Positive people realize that if you live long enough, there are times for great pain and sadness.

One of the most common misperceptions about positive people is that to be positive, you must always be happy. This can not be further from the truth. Anyone who has any depth at all is certainly not happy all the time.  Being sad, angry, disappointed are all essential emotions in life. How else would you ever develop empathy for others if you lived a life of denial and shallow emotions? Positive people do not run from the gamut of emotions, and accept that part of the healing process is to allow themselves to experience all types of feelings, not only the happy ones. A positive person always holds the hope that there is light at the end of the darkness.  

10. Positive person are empowered people – they refuse to blame others and are not victims in life.

Positive people seek the help and support of others who are supportive and safe.They limit interactions with those who are toxic in any manner, even if it comes to legal action and physical estrangement such as in the case of abuse. They have identified their own basic human rights, and they respect themselves too much to play the part of a victim. There is no place for holding grudges with a positive mindset. Forgiveness helps positive people become better, not bitter.

How about you?  How many habits of positive people do you personally find in yourself?  If you lack even a few of these 10 essential habits, you might find that the expected treasure at the end of the rainbow was not all that it was cracked up to be. How could it — if you keep on bringing a negative attitude around?

I wish you well in keeping positive, because as we all know, there is certainly nothing positive about being negative!
