Buy 2 dozen p38 can openers and will never have that problem. I have three in the car (incase i can't find one there are two more) also keep one my key ring and one in my mess kit.

Be sure they're the actual can openers and not the cheap knock offs. Your safest bet is to look at surplus stores, but you can find them online. Just make sure to read the reviews.
For those that are unaware, there's the p38 and p51 can openers. They're virtually identical except for size. Approximately 38 and 51mm long respectively. Buy ether one or both.

Never knew the 51 existed. Picked mine up, the 38s, for dimes at the science and surplus store.
My biggest issue is mine will rust if left in a moist environment. They still work fine though but are not the best subject for showing off.
Side note: these are typically so cheap that you can afford to accidentally obtain a dozen of them. But yeah check the reviews online and save the mental struggle for bigger problems.

I've not tried to use one in decades and was not too successful then. Need to get another & try again.

Thanks for posting these. Had forgotten much of this great info. Let's hope we never have to use these techniques.

I may have some details wrong but am 99% sure on Alone 2015 one of the participants built a sand/charcoal filter
He was evac'd the next day after drinking from it. IIRC,he drank the output directly and did not boil it after he filtered it.
Don't do that!

Yeah, I'd be careful with that one, too.
Heat purifies by ensuring that none but the most remote "extremophiles" could survive. It's obviously calorie-intensive and time consuming, as a step in disinfecting water.
Some microbes are bad because of the chemicals in their shit. Some are bad because part of their life cycle involves a living host.
I've not heard of an extremophile being a danger for humans, just because you'd probably not try to drink the waters they inhabit in the first place. Crypto has a nice protective wrapper that doesn't release until the right conditions are met, so it's resistant to some chemical treatments like iodine tincture. When high heat comes into play, the protective case is destroyed, and so is the crypto.
Bleach has its own method of reactivity, causing damage while forming a 'salt' that usually falls out as a sediment in the water column. Ideally, there's just enough chlorine to react to roughly the same mass of foreign material (suspended solids and microbes) to balance and 'cancel', dropping down the column. This process takes a little agitation and some time to complete.
With both common chemical treatments, contact time is a must. With proper concentration, it should take about 30 minutes... Longer if the water is cold.
If you want to be sure that the scummiest pond water is properly safe to drink, first filter, then disinfect, then boil.
Lastly, Distillation. Distillation would serve to effectively remove the water from any solids by taking advantage of the state change. When the water enters its gaseous state, it can be recaptured as it rises by a surface that remains cooler than the water in the heated container. If the drippings are channeled away to a separate container, you'll have pure water. However, the distilled water will lack many of the minerals the body needs to work well, notably: salt. There is almost always trace sodium in a fresh water source, and its absence from a high quantity consumed could cause a harmful imbalance in a person.
Hope that helps.

So I guess charcoal is the most important part for filtering water then? I wish he would have done this video in the wild instead of with gloves and a microwave in the kitchen but useful info!.
[–] SIayfire122 0 points 1 point 1 point (+1|-0) ago (edited ago)
Honestly I don't know how much more difficult it would be in the wild. The biggest challenge would be not having tools such as bowls and scissors. That and obtaining a container to boil the water.
The key part is the concept though. With this simple concept, you can filter a very large amount of water. If you have a 5 gallon bucket and a metal pot, you're golden. Drill out a hole in the bottom with a knife and layer it like in the video. Since it's so large, you can even add bigger rocks on top to act like a baffle instead of his little plastic piece. Set the bucket on the pot or hang over top of it. Once filtered, toss metal pot over campfire.
And yes, charcoal is the most important part of the filtration. Charcoal is a very, very fine powder that will trap extremely small particles. It's also worth noting that this doesn't sanitize the water, that's what the boiling is for. Other ways you can do this is with bleach, iodine, and UV (sun).
Bleach
Sunlight
Iodine is usually tablets purchased in the camping section.
For boiling, bring to roaring boil for over 1 minute.

Cool. I have seen the concrete rubbing method to open a can before, but it was against the bottom of the can, whereas in this video he rubbed the top. The bottom of the can was said to be easier because the metal is thinner there instead of at the top where it is folded into the seam. I haven't ever actually done it, so not sure. Looks like either way works just fine though.

Yup. This is the third video I've seen with the concrete can opening method. It's the first time I've seen it with a spoon though. I'll have to try that next time I open a can. It looks like the same basic concept as these can openers.

Stealth camping is not exactly the easiest for beginners and noisy normies.
