An ice lens captures the sun’s light and focuses it onto one point, just like a magnifying glass. If that focal point gets hot enough, and if it’s focused on something dry and flammable, you get a flame. It’s such a simple concept, but put to work in a genius way. To form an ice lens, basically you take a chunk of ice and twist it around on the edge of a pipe. The circular pipe edge carves away the chunks and irregularities, and eventually you end up with a perfect ice sphere, which is essentially a rustic kind of Fresnel lens.
I use my chromebook to store a few survival docs, topographic maps and personal data on it and charge it on the move using external power pack or a solar phone charger (it uses micro usb which is just awesome). IMO it rocks but I can understand your reservations.
Anyone new to precious metals must learn the differences between numismatic and bullion coins. Both have their purposes, for investors and for preppers. The values of bullion coins are based almost entirely on their precious metals content. Their melt value is tracked in real time in the global markets, all in terms of troy ounces. In contrast, numismatic coins have both melt value and collector’s value. Judging the market value of bullion coins is simple arithmetic. But the prices numismatics are far more difficult to gauge. This takes study of rarity and relative values, study of the science of coin grading, study of standard annual references, and consultation of current rare coin market prices in detailed publications such as the Grey Sheet and Blue Sheet. There are many complexities that I won’t delve into here in this brief essay. Just suffice it to say, the word complex is an understatement. My general advice is that unless you are willing to do considerable study, then skip rare coins altogether, and only buy bullion coins or pre-1965 non-numismatic “junk” U.S. circulated silver coins.
The null hypothesis for a log-rank test is that the groups have the same survival. The expected number of subjects surviving at each time point in each is adjusted for the number of subjects at risk in the groups at each event time. The log-rank test determines if the observed number of events in each group is significantly different from the expected number. The formal test is based on a chi-squared statistic. When the log-rank statistic is large, it is evidence for a difference in the survival times between the groups. The log-rank statistic approximately has a chi-squared distribution with one degree of freedom, and the p-value is calculated using the chi-squared distribution.

This compass has it all and is very acurate compared with my other compasses I have in my boat and truck. The accessories tucked away within are really cool too. Very compact and a great addition to my survival gear kit.
A Republican member of the Virginia House of Delegates has offended a lot of Democrats with his powerful speech on guns that quickly went viral, raking in over 13 million Facebook views since Friday. Nick Freitas finally hit the nail on the head and…
A good emergency radio is a both a comfort and a useful tool in trying times, especially one that is powered by the sun. But this isn’t just a radio. It also includes a flashlight, a beacon and a cell-phone charger. You can take this anywhere in the world and remain connected, which is maybe the most important survival tool of them all.
Like our earth based hunter-gatherer ancestors, a good survivalist has a relationship with a wide variety of diverse species that can all serve as foods, depending on the season and location. Take a look at this wilderness survival food list to learn more.
Bring survival gear. Basic survival tools such as a knife, a fire steel (metal match), some matches (in a waterproof canister), some cord (550 paracord is best), a whistle, a space blanket, a signaling mirror, water purifying tablets, and a compass can mean the difference between life and death. Even if you are only out on a day hike, be sure to bring the essentials.
An idea on one area that I seem to run into a lot of contention from some people with: electronics. If you’re bugged in and can power them, good for you. If you’re mobile, ditch ’em (most of them). Batteries seem lightweight, but that two pounds of batteries become 40 pounds after 20 miles. Anything that can’t be charged or operated on solar or hand cranks, in my opinion, has no place in a back pack. And of the things that can, many are simply unnecessary. Chromebook for maps, manuals and documents? Get a good smart phone with high capacity storage or OTG storage capabilities with multiple flash drives. Half the weight, just as versatile, twice as mobile. Not to mention, easier to pack.
I described this workshop to my friends as an all-inclusive no-holds-barred immersive business of photography (but applicable to any creative professional) tell-all expose, that also happens to be put on by the coolest photography team on the planet. And you’ll also leave the weekend with 17 rad new friends and a belly full of amazing food and (regardless of the city you are in) the best ice cream around.
Wild edible plants is a huge area of study unto itself. So much so that it goes beyond the scope of this page of our wilderness survival guide. We have devoted an entire section of our website to this study. Take a look here:
So what if you don’t know how to fish, or don’t have any gear? All you need is a shirt and enough saliva to spit. Spit fishing is a quick way to catch minnows and small fish, which can then either be cooked up into a crunchy goulash or used as bait to catch bigger fish. All you do is wade out into the water, lift the front of your shirt to improvise a net under the water’s surface, and spit. Minnows are attracted to the spit—they think it’s food—and when they’re clustered in front of you, jerk your shirt up out of the water.
