- Microscopic footage of dirty water before and after it was filtered with the LifeStraw.
At the end of the video I used tryptic soy agar petri dishes to grow the microbes in the dirty water before and after it was filtered. It was incubated for 24 hours at 37 degrees Celsius.
Camera - Nikon D3300
Microscope - Leica ATC 2000
Microscope magnification of each shot is shown in the bottom right hand corner.

this has got to be one of the best commercials for LifeStraw i've ever seen, a third party doing a purely scientific test and being perfectly honest in what it can and cant do.
100%
No shit?
@@apapz3245 nah i take plenty of shits
Perfectly honest would be showing what colonies grew from the filtered water. He did that, but should have featured it more prominently.
EDIT: Thanks to the 10 people who corrected this very important comment
He did though
I've always wondered why lifestraw didn't do this themselves as advertising.
That's a good question, because if I was going to buy one (and I'm thinking about it now, for sure!) I would have definitely sought out a video just like this to make sure the claims are true! This video is great accidental advertising.
Let's say lifestraw made an ad like this, would you in all honesty believe the results or would you assume that the test had been tampered with?Having independent people do these sorts of tests is the best advertising they can do (and they get it for free no less)
This video is an ad
@@MvMArcher Companies confident in their products are happy to hand over their products to independent TH-camrs for rigorous tests without demanding any kind of positive outcome. "Take it, test it, make up your mind, and let your viewers know" -- LifeStraw could have just done that. If it's a good, novel product, at least one video will go viral.
They did, and vou just watched it.
I used this straw once as an emergency while hiking in Chile. My canteen took a fall and cracked leaving me with no water. Found a stream with some questionable water and went to work drinking. Worked like a charm. Took a bit of effort but got me through the trip. Best 15 bucks I ever spent.
In which part of Chile were you hiking?
Did you survive
@@mrsnail6091 Unfortunately I don’t believe they did.
@@destruxandexploze2552 I heard this too. I believe he's still in Chile. Shall we get ourselves some Lifestraws (not sponsored) and go and rescue them? They'll probably be fine.
@@mrsnail6091 I don't think they survived bro
ive carried a life straw for years hiking and backpacking. Always trusted it, though never used it. I think people misinterpret its use. Its for emergencies to give you the best chance possible with questionable water, not an excuse to not bring clean water with you/boil water on site. Great video.
I think of my life straw like I do insurance or a firearm.
Have it, hope to never need to use it, and take reasonable steps to reduce my chance of needing to use it.
@@Snadzies exactly
they filter 1000 litres. Seems a bit much for 'emergency only'
@@spazco8669 id imagine thats a byproduct of the design for what it is
@@Snadzies what a bizzare and diconnected for actual reality excuse for carrying a weapon. Normal average people being armed increases violence through the threat of escalation, violence in anger, your assailant shooting you with it etc, it doesn't reduce it

Bro was like time to grow some microbes
I work in a lab and 0.2 micron filters are pretty commonly used. Just dawned on me that this is how the lifestraw works and how clever for the inventor to capitalize it for sterile drinking water!!!
Same. I was surprised by how few colonies grew, because we used those filters usually after centrifugation to further purify the supernatant. The filter alone is quite excellent in this straw.
I'm almost certain that the bacterial growth came from other contaminant vector, like the dropper or the petri dish itself.
@@victoriazero8869 it looks like a yeast colony to me, so you could be right. I don't think it's dangerous anyways. you can drink the yeast and it will go in your stomach and die instantly so your body can handle it.
I've always felt fairly safe transferring brackish water from a LifeStraw Go bottle to a Camelbak All Clear UV treatment bottle when boiling in the field is completely impractical
And it's led to these being distributed in parts of the world where drinking water is routinely unsafe. It's a game-changer.
So glad to see this. I just bought 5 so each member of the family would have one.
Buy 5 more.
2 is one.
One is none
Agh bad decision! Should have gone with a Lifestraw Go, much easier to use than the lifestraw and is much more of an essential item.
Sad that I returned my 4pk.
i would buy one if i actually had use for it, I drink out of a bottle all the time. lol
@@lokey416 it’s intended more as a camping/survival item. Less so everyday use
This is so useful to know I was always sceptical of lifestraw
Honestly, I didn't know what to expect but it was fun to learn what it is capable of.
Oh yeah yeah
OH YEAH YEAH
@@sci-inspi at least it works as they've claimed
@@sci-inspi Can you also test one of the cheap alternative filters from amazon that are no name brands ? Like Finerfilters or Lixada or Sawyer or Hydramate.
I got to be honest, this is far above my expectations.
works better than I thought it would, and I have one already.
Well It uses standard 0.2 micron filter fibre. I assume made by the couple companies that make such fiber. as long as the filter cloth is reliably made.... There isn't much to go wrong. Many much more expensive filter units use same filtering size. Mostly lifestraw is cheap, because it is bare bones. Their whole unit cost kinda what some filter replacement ments costs on other units. Which pretty much tells the story. Lifestraw costs what their filter element costs. It is filter element in a tube and the tube costs nearly nothing.
It isn't magic. Just bare bones. Also since their unit doesn't cost that much less than what replacement fibre filter units costs on other devices..... Filter materials come from similar grade sources.
On other units one is paying for the pumping units, extra secondary filters, active carbon catridges and so on.
And should one go much higher in price, then one can start to see just even smaller filter size.
Go all the way and one has reverse osmosis kit, since filter is tight enough to filter out salt molecyles.
I think the conclusion is that you can still get sick or die since it doesn't filters viruses and those other things mentioned. Am I right? If I am wrong then why is it that you think I am wrong? Thanks.
@@taowaycamino4891 That isn't entirely incorrect, but viruses, heavy metals, and pesticides (the three items mentioned) are far rarer than bacteria and protozoa.
In a remote location that isn't near farm land or an industrial complex you don't need to worry about lethal amounts of heavy metals (things like uranium, lead, gold, and iron) and pesticides (chemicals used on crops typically to kill bugs), as those problems are almost entirely man made.
Viruses are a bit more complex, but they cannot survive long without a host. The normal way they spread is by being excreted through a living being already infected with it (relevantly right now through sneezes), so the only real danger is if there's an animal corpse upstream and even then the viruses can't necessarily infect humans, as they generally specialize to best infect certain types of animals.
Bacteria and protozoa are generally likely to cause illness, but live everywhere in massive quantities, so the chance of at least a _couple_ of them being dangerous is extremely high.
Bottom line is that the product decreases your chances of getting sick from a near guarantee to an anomaly.
@@taowaycamino4891 I’d say that it’s still something good to have should you find yourself stranded and without a clean source of water or if you run out of water in your bottle while hiking. Even if it doesn’t work fully it’s better than drinking straight from the stream.
They need to just have this vid be their commercial because now I want one even though I'll prob never need it
Plot twist this is the ad
If they do, they better pay me.
I wouldn't have believed them. My dude here is a 3rd party with no reason to lie to us, so his experiment is much more valuable and believable.
they are excellent to pack away in an emergency kit.
Lol same. 🤣
I was gifted a life straw like 3 years ago, still sealed in the package. I've saved it for emergencies or whatever which never came but you never know. Kind of cool to see that it does indeed actually work pretty good.
Same lol got it for Xmas like 4 years ago
Does it have an expiration date?
@@redgringrumboldt8983 I think it have expiration date. Not 100% sure. I have one still new.
@@redgringrumboldt8983 yeah well if we don't take into account plastic degradation over decades then no, it doesn't have an expiration date.
@@masterrzeke Well I was inquiring about the filters on the inside, how long they would last before they became less effective?
A lifestraw is definitely a must have. I'd also recommend the slightly upgrade one that comes with a flexible water bottle because you can collect water, it's easier to use, and it has a carbon filter so it's even better
There's better quality filters out there than lifestraw. Sawyer makes their squeeze which has been a favorite among hikers and backpackers for years. Platypus is also known for a good gravity bled system If you want virus elimination there's some purifier, UV, and tablet options available too.
Lifestraw also has a carbon filter iirc
@@twizz420 That doesn't stop viruses. You need a 0.02 micro or smaller filter for that. Lifestraw is a 0.2 micron filter. The Sawyer Squeeze is 0.1 micron. Suvivor sells a $30 straw type filter that's 0.05 microns which will get a lot of viruses but falls short of the EPA regulation. They have a pump style filter that's down to 0.01 micron that you can get for $60. There's 0 reason to get a life straw.
A lifestraw's made for backcountry water in north america where you can expect the water to be fairly clean. Chile's no going to be as save water wise.
@@Furluge As a hiker I completely agree and those are my 2 filtration systems I use hiking.
Platypus for multiple people or when weight is less of a factor. Extremely easy to use and can filter a lot of water quickly. This is my go-to for 90% of trips.
Sawyer squeeze for ultralight / single person use. It weighs under 100g though it is more effort to use. Also be careful not to lose the o-ring when filling. Most common filter for people on the PCT.
@@graham1034 I've got a platypus and I had been looking to get a sawyer squeeze but it looks like the innovation has marched along and I think I'm going to swtich over to a suvivor pro system. That one'll take out viruses and heavy metals so you can use it more areas. They've got a stray type filter that goes down to 0.05 microns too that's very cheap.

It'd also be interesting to see the lifestraw filtered water compared to some of your tap water or filtered water that you usually drink at home as a control!
With the disclaimer that tap water varies from area to area though! Where I live tap water gets strictly controlled, it is supposed to be even cleaner than bottled water from the store.
Now that would be concerning to know u have crap water compared to the straw
Most municipal water supplies are laden with chemicals to keep it “safe”. I have a gravity filter that takes 24 hours to filter one gallon through and I filter all my municipally supplied water for consumption in to get all the chemicals out. The filtered water tastes much better - sometimes the municipal water has a bad chlorine taste, probably bad growth of bacteria in the water.
@@u4riahsc laden with chemicals lol? Chlorine only, laden with nothing and safer than bottle one
@@u4riahsc Unless you live in a third world country, there's nothing in your tap water other than residual chlorine (unless you have contamination between the curb and your taps, which is your responsibility as the property owner). Municipal water is disinfected by chlorine or ozone at the plant, then buffered with chlorine while in transit to your home to maintain disinfection. If there are other chemicals, your piping requires replacement.
Such an amazing product. Pretty sure I’ve heard these things are being shipped to spots around Africa where clean drinking water isn’t anywhere to be found. Literally saving lives.
there’s only a few countries in Africa that has water insecurity not the whole continent the Africa adverts on tv did you dirty lol

@@DimT670 I understand that Africa is gigantic and has many countries within it with many different cultures, practices, and biomes.

Take your overly sensitive negativity and shove it up your ass. Get a life.
LifeStraw actually saved my dads life. He went hunting in New Mexico and ran out of water on a hot 90 degree day. Ended up getting heat exhaustion. He was on the brink of death until he crawled into a little muddy bog, with no water above the surface. He was able to use the straw and he and his buddy ended up surviving.
I'm so glad they are both OK! It's a good thing they were prepared, you just never know what can go wrong until it does.

LifeStraw is one of those breath of fresh air products that actually do a VERY good job, and could ACTUALLY save your life. I keep one in my car at all times, and it's definitely something you should carry in your backpack if you're gonna do a longer hike or outdoor adventuring.
It makes sense that it works now that you mentioned a 0.2 micro filter this means it will filter all harmful bacteria. This is also called sterilization filter and its widely used in pharmaceutical industry to filter air and liquids.
So it doesn't work is basically what you're saying right?
Theyre saying it works, the harmful bacteria cant make it through the 0.2 micro filters.

Well it was made to be used in places like Africa. If they had tried a scam Charities would have called them out pretty fast. Life straws are often given out by charities.
@@brokeandtired you would like to think so. Look at how many people believe in crystal healing and that essential oils will cure cancer.
@@brokeandtired the charities are scams
Part of you said it was a scam, so you made a judgment based on nothing. A few minutes of research would have taught you that these lifestraws are used the world over by soldiers, explorers, hunters, missionaries, etc. People are so lazy and quick to judge with zero intelligence invested.
I found out about this several years ago. I think it was just one guy who came up with this simple and cheap system to help get people clean water. I'm happy to see it gain attention.
Very interesting, thank you very much.
It would be fascinating to do a similar test on tap water before it reaches a fridge's internal water filter and then test what comes out.
Even better would be to test with a filter that has reached its prescribed replacement period and compare it to a brand new filter, to see if those 50$ filters really need to be replaced as often as the timer in the fridge tells you.
Those filters on the fridge barely do anything, my tap water has a total dissolved solids(TDS) of 330 ppm, while filtered fridge water has a TDS of 230 ppm. Spring water from a natural spring has TDS of 40 ppm. Best not to drink tap or filtered fridge water.

@@snowcow1173 Good luck strengthening your immune system to lead, arsenic, and microplastics. There is much worse than bacteria in tap water, unfortunately.
Great to see that LifeStraw's claims are proven. I often hike, canyon, MTB and go 4WDing, and I've always had one in my 4WD and another in my backpack. Though I always make sure I carry enough water for my activities, but have the LifeStraw as cheap insurance in case of emergency.

@@lovecheese45 According to their website, shelf life is indefinite. And up to 4000L (approx 1000 US gallons) of water when used.

Of course, it's designed to filter anything
I would have thought rain would be largely free of microbes, if it hadn't touched ground yet.
@@Christobanistan The potential danger is the water is sitting in open barrels for an extended period of time, another potential issue was people would dip their hands in the barrels throughout the day for a drink.

Glad to see these things work so well. I keep one in my BOB but haven’t had to use it yet.
It’s worth noting that multi-stage filtration and boiling is still superior, as you can filter to a similar degree and then kill any remaining microbes. If you use charcoal in the filter you will also remove a significant proportion of heavy metals and chemical pollutants. For heavily contaminated water, filter several times before boiling. But obviously that requires stopping to set up a fire and a filter station. It’s also worth carrying a pack of ph test strips in your kit to help measure water quality.
How much use is testing ph? it would, at best, tell you if its going to burn you or not. Bacteria do have optimum PH ranges, but im not sure how much of a check the ph of water is
Wouldn't boiling the water and collecting the vapor in a kind of destillation process the best option? I am really bad at chemistry, so there are probably still pesticides and heavy metals that are water soluable which would be in the vapor, right?
@@Medhusalem distillation like that is fairly reliable. Cant say its perfect, cause i dont know, but its pretty darn good. The issue is distillation is energy and infrastructure intensive
@@ciarangale4738 what do you mean? You won't encounter water that is outside of a pH that is drinkable. Maybe if you're in a super volcanic area that's known to have very alkaline water, but you'd know that going in. No need to test pH.
@@littlejackalo5326 that was my point. I couldnt see how carrying PH strips could be valuable for finding potable water
Great video that shows a product that works. I never bought a LifeStraw because I didn't like the idea of drinking directly from a highly questionable water source. I'm with team Sawyer. But seriously, scoop out the water, pre-filter it using a piece of cloth a few times, filter it using the LifeStraw or Sawyer, then boil it if you're still worried about it. Whether you believe it or not, pre-filtering actually removes a lot of contaminants, and of course it depends a lot on the type of cloth you are using, but it still works even if you are using the t-shirt you're wearing.
Life straw actually has a lot of different types of filters now... I have one in my fridge for water.
@@backwoodsbaby9729 , I'm arguing from the same perspective as the video, that is for the outdoors like camping, hiking, biking and specifically SHTF. I might go as far as to say that the filter in your fridge cannot perform this task. And even if it could, it would be severely limited by the volume of water filtered before it breaks. Your filter is for 1st world problems, where the water is so clean that the chemicals that make it clean are purportedly killing you. It's a final stage filter. I have a 2L water jug with a filter on my kitchen counter for that as well, but I would never use it to filter water like in this video.
@@jdshl8423 check out the line of products they have before assuming things. I wouldn't put sediment filled water in it but I could put lake water in it.
Pre-filtering extends the lifespan of that very fine filter. Get the big stuff out so the LifeStraw only has to tackle the little guys.
What’s team Sawyer?
Love Lifestraws. I always have one in my hiking/camping pack. I’ve drank through it from mountain rivers and streams, still water, lakes, ponds, etc without one single issue. They’re great for when you don’t want to carry around a larger filter system if you’re just side hiking or trying to move quickly through an area without taking a break
This is about the dumbest application of lifestraws you could think of. They aren't a replacement for normal drinking water. They're for emergencies when nothing else is available. You're still risking waterborne viruses for no reason drinking through a lifestraw when you have other options.
But somehow the thought of a clown like going hiking for a few hours and stopping to suck pond water through a lifestraw is hilarious.
@@bigquazz3955 Well now we all know who here has never been on a backpacking trip or hiking trip that lasted for more than 3 days lmao
When you take a 10 day, 100+ mile trek come back and tell me how this is stupid.
Also, most of my treks take place above 10,000 feet elevation, where contracting viruses from water you’re actively filtering through something like a Lifestraw is exceedingly rare. Lifestraws also expire. I only use them for about half of their stated use time. Then I get new ones
It’s also not my primary source of purifying water, dumbass.
Uhh dude that's not what its for
@@bigquazz3955 I'm just imagining seeing some dude bending down to suck on pond water through a straw every few hours. Fucking hilarious.
It's intended for emergency use only so the fact that it does so well is great.
I bought one of these for my daughter who does back country camping. She was the only one in the group who had one - everyone else including her were using tablets. Now they all purchased the Life Straw - it works wonders. She even told me when they were canoeing she just leaned over and took a drink from the lake with the straw.
🤢
I'd be fucking pissed if the other person in a canoe with me tried to lean over the side like that. That's how you end up with all your shit in the water.
she leaned over and took a sip of the lake lmao wtf
@@uno9915 I wouldn't do it with a lifestraw unless it was an emergency, and certainly not over the side of a canoe. I actually question the validity of the story based on that claim. Have you ever tried to get your face within 6 inches of the water while in a canoe? Shit moving more than half your body 6 inches from *center* is enough to start making the other person in the canoe work to stay upright.
We carried mugs on our packs and dipped straight in the lake and drank. This was northern Canada. We rarely treated or filtered water. Never an issue.
I love when a product delivers so well.
Thank you for posting a video where you do some science properly (I assume your techniques were all performed properly)! Only just found your channel and super impressed. So stoked that at every step you made comparisons between unfiltered and filtered water, as well as going beyond the visual assessment and doing some lovely, simple, microbiology work - and stating your limitations/sources of contamination!!!

That’s pretty amazing how well those work. Also microscopes are kinda scary, unveiling another world invisible to the naked eye. I would love to get a microscope to look up close at everyday items around the house lol
I’m not sure you would lol!!
As somebody who's naturally curious as well and had a microscope growing up, I'd recommend against looking around your house with a microscope. You'll "bug" (haha pun kinda intended) yourself out. It's amazing what accumulates in living spaces. Unless you're an OCD riddled hypocondriac, your house is nasty under a microscope. Most things live in harmony with us, either helping/ignoring us or being generally harmless outside of the body, but it's still really freaky to see *exactly* how many microbes are chillin on your doorknobs, faucets, devices, and floors. Unless you harcore sanitize your kitchen top to bottom every day, you'd probably be pretty grossed out in there too, and maybe even still.
What would happen if you actually drank that dirty water👀
@@anna.318 hard to say, depends on what's in it. Likely diarrhea, stomach discomfort and possibly fever until your immune system deals with whatever microbes were actually in the water.

Lifestraws are a solid investment for anyone who spends a lot of time outdoors, and away from the comforts of home. Great product and great video!

I'm so happy I found this channel! Very fascinating stuff, It's nice to be able to take a glance into a whole new world that's on a microscopic level. Thanks for posting videos!
This is great for camping! Me and my sister use it. We try to find moving water, but we don't trust it entirely, of course. That's where the straw comes in to play. Really nice to not drag 4-5 extra kilos of water along for a two day trip!
Could also be great for an emergency, in case one gets stuck and needs more water
Why moving water?
@@hi-zg2wqits harder for bacteria and viruses persist inside moving water, there are also natural filters in these waters and the bacteria basically move with the flow ig
I was actually always curious to see if virions passed through, this is really interesting
Great vid ^^
They do because they are really tiny.
@@sci-inspi
How about a Pandoravirus/Megavirus/Tupanvirus?
any of the large viruses.
this is really interesting (duh) lol
The bigger ones get filtered out in the LifeStraw. Anything bigger than 0.2 micrometers will not pass through.
@@sci-inspi thanks
@@sci-inspi (Sorry, dumb question)- It is DEFINITELY better than nothing by far right?
They should pay you $ for this lol, srsly, I’m considering buying one of those for my next hike lol
@@Davidxdlol How is it useless?
Make sure there's no virus in your water, those things are sooo tiny
@@Davidxdlol It's useful against bacteria, which is the biggest threat.
Don't get a life straw, there are many other brands out there that screw on to bottles or come with bags/bladders to fill up 'dirty water' and let gravity do the work. They're also much cheaper than a life straw which you'll want to throw away the second or third time you use it.
Sawyer filters are probably the most common among hikers.
Carter Wilson Ive used both on 3 day backpacking trips, both were good in a bladder set up and i was filtering clay packed water from dolly sods
Awesome to see! I've drank from numerous streams around the Austin area, in the San Juans in Colorado and the Virgin River in Zion. Has worked great for me and I've never gotten sick. 👍🏻
@Montañero Paisa not worth the risk bro
@@hahaahaha6414 why?
Water gets contaminated if stagnant, streams are less likely to contain any heavy pollutants
The rare occasion where I am pleasantly surprised by a product that performs as advertised. Thank you.
That straw is pretty damn impressive. I was skeptical.
"Lifestraw can't filter heavy metal."
Metallica: *Ooo yea!*
If you were a bacteria or protozoa you could say that this straw is a harvester of sorrow. Perhaps the one. As you are sucked up into it things begin to fade to black.

I remember the advertising years ago, and never thought it was real. I am in complete disbelief honestly. (Thanks TH-cam recommended for enlightening me with this beyond beautiful video).
Love the peaceful music in this video. No loud obnoxious talking. Great video!👍
That was fascinating!

You should watch MRE reviews lol it’s good for people with ADHD
Good thing to have. I personally keep mine with some resturant sized coffee filters to filter out the big stuff from the raw water source. While not perfect, it is good enough to prevent you from dieing of dehydration, contracting dysentery causing bacteria or getting parasites like tapeworm. Goes without saying that useing iodine or even bleach tablets are preferable when boiling (BEST option) isn't practical
I am glad to see that Lifestraw works! These videos are so mesmerizing
I read about Lifestraws many years ago and thought they'd be a great idea for people in Africa and other places around the world where clean water is not always available.
It's great to see how well the Lifestraw works and they would be a life saver in many ways. A great idea for hikers, adventurers and backpackers.
And remember folks, always boil your water AS WELL. And never ever drink from a stagnant water source.
Good advice.
Doesn't this video disprove that you'd need to boil your water if using LifeStraw?
I love the vid so much! Always such good music choice. I know there probably wouldn’t have been anything significant but I do wish there was a control Petri dish with a sample of the water you used before adding the yard trimmings (;
When it said "meets US safe water standards" it actually made me more doubtful I would be satisfied with the results but I was actually impressed
Tap water in America comes out as fire or mud sludge, how is that meeting their own standards? 😂
@@madeline569 And where exactly? Literally no tap water comes out like that unless its unfiltered well water that just started being pumped
@@remizu2901 Flint MI is one example
@@Jimmyknapp2 are there any others? I don't know about you but anytime I get water from a tap, it's always clean
@@insanebro4476 Pretty sure there are a lot of areas around fracking plants that had issues with dirty water
Thank you very much for this non-biased video! I bought a LifeStraw a couple years ago but was always afraid to use it..
They don't expire so you should be good until you need it!
I really like the channels that has limited to no talking.
Nobody:
Protozoa: _they're groovin'_
Shut up
O M G so funny the way you said "Nobody:". I was so ready to not laugh but then you made it a meme, and let me tell you, WOW. JUST WOW.
shut up
I wonder when the Tozoa go Pro?
oh yea woo yea
If you want to do a Pt. 2 you should test the performance after filtering certain amounts of water. For example get a larger sample of dirty water and only use that water for control, and then test how much is left over after 1st use, and then after pumping 1, 5, 10, 20, 50 litres of the dirty water through it.
I don't work for Life Straw but I've dealt with them in a retail environment and I will say they're not trying to sell you your daily use water filter. This is an emergency item to use if you're stranded and things haven't gone according to plan. If you're planning a backpacking or camping trip and intending to filter all your water, there are more resilient alternatives designed for that (including Life Straw branded ones). Some of them are even water bottles with a filter in the main chamber!
this song is very comforting to me, i listened to it alot when i was going through some tough times. thank you!!
A life straw saved us about 5km of extra hiking on a portage and we still talk about it! 😄🙌
Glad to see it lives up to the claims! 😀great vid thanks!
I'm just starting to watch some of your vids and I really enjoy them!
One recommendation I have is to add a control and put the original "clean" water under all the same tests. I'm no scientist but feel that that could be important.
Other than gag factor for what's in our tap water. There isn't a point.
He used some water to grow microbes, doesn't matter if it already had bugs in it.
@@backwoodsbaby9729 that's the whole fucking point.
@@backwoodsbaby9729 it's just to have a control, to make it a little more scientific

Just found this, and subscribed. Thanks, I love what you are doing :)
Can you show what "prepper" filtered water looks like under the microscope? Where they take sand, charcoal from the fire, and other outside elements to create a "water filter" from a local source/pond?
I’d love to see a Berkey system under a microscope
no
I agree, would be nice to learn more about it and see what it can do
Me too.
i'd love to see a microscope under a microscope
Id love to see paul allens filtering systems
The dust is probably carbon from the filter as it needs to be wet to work and usually loses a little when first used
No, the standard Lifestraw model used here does not have an activated carbon filter component. It is only the hollow fiber filter. Some of their other products, like the Brita-style pitcher, do have a secondary carbon filter for chemical contaminants and taste
I think the conclusion is that you can still get sick or die since it doesn't filters viruses and those other things mentioned. Am I right? If I am wrong then why is it that you think I am wrong? Thanks.

I use it all the time when hiking. Thanks for the content.
Fascinating video, thanks! I lost my Lifestraw supply back when I left LA a couple years ago. I had them in my earthquake preparedness kit. Glad to see they were a good idea! I'll pick a couple up again!

we can see your profile name dumbass no need to put your initials on a comment jesus christ people are fucking stupid.
The colony forming units that did appear in the filtered dish could have been from the air or the tube attaching the graduated pippette with the Lifestraw, would be interesting to see this test replicated a number of times with sterile tubing, etc.
I used one once just because we had it and wanted to test it out. Really relieved to learn that it actually works. Had no idea if it was legit or not in a real stream. We didn't get sick so that was enough evidence that it worked. Just glad to learn its legit
I've always had my doubts about these types of things and now you've just cleared those doubts
Appreciate your time and effort into this it really helps me explaining and conversating with people about what lifestyle can actually do
Seeing all the bacteria through the microscope was cool. It was like a little civilisation.
I thought similar, it made me think in every bit of this world there is life...kinda brought me back to 8th grade science
I love the music, it makes the video. Thank you
Awesome , Thanks Sci-Inspi 😊
I would have been interested to see the comparison under the microscope and on the Petri dish with plain tap water before the microbes were grown with the leaf detritus. Have you ever tested the carbon filter on those “Bobble” water bottles? I always wondered how much they really filter out.
The madlad actually did it! Thank you :)
It's amazing how much life is in such a small bit of water.
Not really, there is tons of microscopic life everywhere, including inside of and on you
I have these in my BOB and my "get home bag" in my pickup. Nice to know they actually work pretty darn good. Thanks
1:25 Unlike bacteria the protozoa knows how to party.
Huh, from a microbiology perspective, that is really impressive. That water grew fewer colonies than some of the regular tapwater.
Well one thing is for sure about the AFTER image.... it showed me how filthy my screen is.

@@firepuppies4086 heaven knows I'm not"rich". I clock in every day. "Corporal's Corner ", you tuber has some good vids up on other press methods for water purifier 👍
Heavy metals and chemicals wont kill you right away tho, and viruses arent super common in water.
Being stuck at quarantine with a microscope is surely the best.
That's legitimately incredible.. It's more effective than boiling. Bravo, Life straw
I take various forms of life straw to Cuba for my friends who always have intestinal issues due to the water. I use the LS water bottle as my daily drinking device. They work well and are way more affordable than buying water or even boiling water with propane. I’m surprised they don’t market to places with low water quality?
Protozoa: *J I G G L E*
Bacteria: *dancing*
Go need to do a check on the next best thing, that is supposed to actually work - Geigerrig In-Line Virus Water Filter. Looking forward to it!
Great demonstration. I haven't needed to use my life straw but have confidence in it now.
"I used one of these straws on Mars one time, I was walking alone and... TBC" My question is... is there another simple filter like this that *can* filter viruses, heavy metals, pesticides, and other chemicals?
I dont know about heavy metals (good call!) but GearSkeptic (th-cam.com/channels/flIoVkAjQnyAwDKFmhRDDw.html) has been doing a series about water purification lately. The latest video goes over viruses. His videos are really thorough so maybe its worth a look!
@@covey656 Muchas gracias mi amigo.
@@covey656 Thanks again... he has certainly done his research.
short answer, no that's not possible. The only thing that would do all this is a very fine reverse osmosis filter, but that's not going to be a simple or cheap device
for viruses you generally want UV treatment on clean (pre-filtered) water, there are travel devices for both
for chemicals (including heavy metals) you'd need to add an activated carbon/charcoal filter
@@user-qn9ku2fl2b I've been using an MSR Guardian and a Steripen Ultra for years with no negative effects, so..... cool.
I was always curious about this product but I'm interested to know what kind of bacteria grew in the Petri dish? Great video btw.
It looked like a colony of Bacterlus Germosis
I would like to know if the amount of "stuff" in the unfiltered sample is enough to make some one sick. That said, the filter will definitely keep you alive for a long time. 1000 gal. IF you have a water source.
I would say, those microbes were most likely from outside contamination after the filtering of the water...
We live in the mountains, and travel often. I have one of these in each car, along with our other survival supplies, so this is cool to see. Thank you!
