@BenCrowell Btw, did you even watch the video? The water used is definitely not what you would call "probably clean".

@BenCrowell Some people would recommend to NOT try to find your way to safety and instead stay put. Also, keeping yourself busy can help you stay busy and calm. Even if you built the water filtration device and never use it; it may have served a different purpose. I don't see how this is relevant to the OP question. The question is not "please debate the usefulness of creating such a contraption" but rather the purpose of one of its components it. Feel free to create a question where it states "Should I create such a contraption? this would be much more appropriate.

I actually agree with you on backcountry water but this is not a backcountry camping question. The video referred by the OP is about filtering water and not purification. i.e. You have brown water, it is the only available water, what can you do with it? Yes, it is a hypothetical scenario fitting, in my humble opinion, with the topic of survival. I think you are confusing survival and backcountry camping tags.

@BenCrowell In survival situation there are many scenarios where you may not have access to a pristine water source in which case you might have to deal with whatever is at hand. The author of the video also mentions that this is just for water filtration, and not purification.

We already have a similar question on TGO: outdoors.stackexchange.com/questions/4156/… "You are likely talking about eye flies. They feed on lachrymal secretion which your eyes produce."

comment Reacting to tornado warnings while camping with no buildings nearby
@Kate Gregory It most likely depends on the circumstances: how much advance warning you have, how fast the tornado is traveling, and how close you are to its direct path. Probably better to err on the side of caution and take only what you need (first aid, clothes to keep you warm/dry, some water and food). Losing a tent or canoe is no fun, but it's better than being severely injured or killed.
