comment Why do flies try to get in my eyes all the time?
To me they are different questions; Why do they fly in my eyes? How to deal with them? I referenced to other question because one of the answer explains the why.

comment Water filters - why sand and rocks?
@liam The question you suggest is off-topic to the question being asked. Please note that the question is tagged with survival. This means, it is safe to assume that a fast flowing stream is NOT available. To me this is like someone asking which car is better to drive to London and having someone argue that you should fly there by aircraft. It may be useful input if I'm questioning the best mode of transportation but if I really mean to compare different cars for that specific purpose, the comment is quite unconstructive.

@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.
