Cotton kills - but only when not in water. Whilst in water, cotton will not have any thermal effect. However, the material itself can easily wear you down through drag. You might be able to swim...
Although it may seem extreme, I often disconnect my battery before embarking on a hike. Especially if I am in a remote location. This is a nice way to ensure there is no slow electrical drain that ...
Mangroves no, because if you compare this map of the distribution of mangroves to this map of the distribution of alligators in the United States, Image Source there aren't any places with man...
You are not allowed bear spray in Yosemite. It is also illegal to discharge a firearm for any reason, but you are allowed to transport your gun through the park (assuming you legally own it). Addi...
Pl@ntNet is a citizen science project based in France. It's a great way to identify plants. To you use it you take one or more picture of a plant and then Pl@ntNet will upload them to a server and ...
Most of these I have experience with the supporting arms are the weak point - hit them and they bend, making it hard to take the target apart for storage, keeping the target from spinning/flipping,...
Just for reference: in thru-hiking terminology, dry camping is camping far from any water source. It basically means that you have to carry all the water you'll need for the evening and the next da...
Linseed oil is used because it's a drying oil, A drying oil is an oil that hardens to a tough, solid film after a period of exposure to air. The oil hardens through a chemical reaction in which...
The little birds may have been exposed to insecticides, like Imidacloprid by eating contaminated insects. It doesn't take much Imidacloprid to kill a bird as small as a hummingbird. Imidacloprid wa...
Without having more info on the specific parameters of the study, it's hard to know exactly what they were looking for. Either water or snowpack characterization might be very likely subjects. I'...
As someone who has been stung twice by bark scorpions in Arizona, I also advise taking an antihistamine like Benadryl to keep inflammation down and decrease any minor allergic reaction. (Beer also ...
I've worked extensively with the Aguila subsonic .22LR loads. Out of a full-length (i.e., 18") barrel the 40gr runs about 1035fps while the 60gr barely breaks 900fps. So both are soundly subsonic...
I teach survival. I live in Malaysia and our jungle is the Equatorial Rain Forest, which is usually damp. Hand road flares is something I would put in my pack in case I need to make fire or signa...
Mold doesn't need light to grow, in fact it thrives in darker environments. It needs warm temperatures, water, and food (sugars/salt from backwash). So those three things are independent of water b...
As other answers have already explained what SPF is, I will focus on an aspect of high SPF sunscreens that has not been discussed here yet. There are two ways sunscreen can work. The first is by ...
I'm not 100% certain, but they look like a young Rattus genus. They could also be Mus genus (common house mouse) - most of these genera are pretty similar with a pale belly and darker dun dorsum. Y...
Theoretically, it might be possible to survive on fish, rainwater and desalinated seawater. In one 1930 experiment, two men survived for a year eating exclusively meat without experiencing any heal...
As you are looking to rappel for fun, you should find a place better suited for it. As you mentioned, the anchors are not well situated for an easy rappel. If you want to rappel off that cliff, jus...
No. If the boots have a Gore-Tex membrane, this is a PTFE film that is sandwiched between the inner lining and the upper. Light going through a glass pane is mostly harmless. For example, most of t...
For most people "swimming" is just splashing around and having fun in the water. If this is the case, heavier materials like cotton and denim are no more dangerous than anything else. Just take a...
One solution to your problem is UHT (ultra-high-temperature) milk. UHT milk has been treated at a high temperature to kill all bacteria, making it shelf-stable for at least 6 months. Once opened, h...
One thing you can do is close up the gap under the fly sheet on the upwind side using something you already have. That's easy for me - I go bike camping and my panniers are heavy duty dry bags that...
Zip-together bags would be the best solution but if you already have a double then just fold the sleeping bag in half and sleep in the top half with the other half underneath you. You get extra cus...
Dry/powdered milk used to be much cheaper than liquid whole milk, since our family of 7 (5 kids, me in the middle) grew up on it, mixing it with liquid milk. I have used it sometimes since, and it...
Assuming you are a somewhat healthy individual and not camping in an avalanche zone, you probably do not need to worry about suffocation. With enough accumulation, your tent will collapse, at which...
