Water Purification Tablets, Part 2

Watch Part 1 here: • Water Purification Tab...
An experiment testing water purification tablets on lake water, and examining the water through a microscope and a petri dish. The tablets are only effective against microbes and not heavy metals and chemicals.
The medium used for the petri dish was tryptic soy agar. The dish 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.

Vegans watching this be like 😭

[@susbox5554]

The music is always awesome the reason why I'm here for the science and music

[@hardtrekkingsurvival]

As you mentioned in the first video, and it's mentioned by all the scientific papers and usually by the tabs instructions as well, they describe that in emergency situations the first step is to filter the water, using a mill bag, a feminine swab, an improvised filter made from grass, pebbles, sand, charcoal, etc., and only then use some kind of disinfection procedure/device.

[@ifell3]

Update pt 1 with this video, will make it easier for people to find it!! Thank you for your hard work. I actually find it relaxing watching them survive before the tablets aha

[@sci-inspi]

Done, thanks for the idea.

[@nabu213]

I love your music so much

[@maybar66]

That lake water was cleaner than I thought. Can possibly you do a comparison between lake water and river water sometime?

[@southern_pride0]

i can tell you that river water will be far cleaner

[@sexwax4191]

Could you try this out with a selfmade gravity filter as they are taught in survival classes? They consist of three layers. Layer one is a fine fabric, layer 2 consists of gravel & sand, layer 3 consists of leftover charcoal (e.g. from a campfire). I would really be interested in seeing how well this method works.

[@capitalismsucks9590]

My same question. I was planning on doing this, having a micron filter on top with gravel layer and sand layer and charcoal stick layer, with another micron filter on bottom. Then boil the collected water.

[@sexwax4191]

@Rich Moore the reason for the three layers is to mitigate the clogging issue in more polluted water. Also it is a 'standard' filtering scheme for survival situations, where you only have basic materials. Of course, having better equipment one can and should optimize the setup.

[@alexscott8950]

The outcome would be the exact same.

[@rolandlee6898]

Thats meant to filter out particulates not bacteria.

[@Templarfreak]

as round lee says, this setup is not really meant to disinfect, just filter out large particulates. after doing a bit of cursory research, it seems like it may be possible to modify this setup by adding an additional layer of activated charcoal, or filter the water through activated charcoal after you filter out particulates (and then filter out the activated charcoal in the previous filter afterwards). this could potentially last you through a decent amount of filterings without needing to disinfect the water by boiling it every single time, as well, but this is all mostly conjecture from doing a bit of googling lol not entirely sure what kinds of processes you'd have to go through to make activated charcoal in the wilderness, but it shouldnt be that much different or more difficult than making it at your own home.

[@PsychoLama2023]

First I wanted to say thank you very much for taking the time and the effort for this experiment. Second as an avid outdoorsman and woodsman. I do have one question I’d like to ask you, would you be willing to do another video/experiment, where a coffee filter is used to filter the treated water?

[@GrandHighGamer]

Can't see it doing much apart from removing the largest particles. A coffee filter is only intended to filter out grounds. They wouldn't much use if your coffee came out as just water on the other end, after all.

[@AtsukiMai]

As usual, the music is soothing.

[@Kaelland]

This makes me wonder if one were to take your turbid water from the first experiment, run it through a crude filter (a clean T-shirt or dish towel, for example), and then try the purification tablets again, would they be more effective? And if so, would they be effective enough?

[@sci-inspi]

It would be more effective, but I don't know if it would be enough.

[@Kaelland]

@@sci-inspi It might make for an interesting part 3. Plus, your methods are more scientific and safer than me going "Well, let's try this and see if it makes me sick." :)

[@DiedLiu]

I checked last video, didn't see him put tablets into water, so maybe that's why.

[@ramyarams256]

More than anything else, the music is great!

[@bp8652]

Good to know iodine tabs work on clear water. I've used them many times canoeing and was slightly concerned by your first video.. Also,, We always avoided filling up bottles where there were waterfowl present. We called water fleas "swimmies" before treatment. Afterwards they were "floaties"

[@DJPach]

lol, I was relieved as well since I've also used those tablets in the past!

[@gilem.8784]

The song on this one is so good

[@DRMrThi]

I would love to see Kefir milk under the microscope 😀

[@user-et5mz5ex9s]

I've had these exact same tablets for a few years now and I luckily haven't needed to use them, but I've always wondered of their effectiveness in killing a culture of bacteria and the quantities in which they are most effective. Thanks for making this video. 👍

[@Davis38]

Your videos are so interesting! Could I suggest taking a look at how alcohol and different concentrations of it affect microorganisms? I heard that alcohol below a concentration of 60% and pure alcohol are less effective than anything in between. Could you test that? Thank you!

[@umusuariodoyoutube5528]

Great video and music too.

[@dbpgh]

Everything else aside, these 2 water videos i just watched are great before bedtime…goodnight everyone

[@luismiguelmoreira1431]

Very good video Sci-Inspi, waiting the next one, greetings 🙂👍

[@TapeDeSpencer]

I’d like to see how the stomach bacteria looks before and after those tablets. :/

[@xdeathknight72x]

Great follow up video Thanks for making this!

[@jasonvoorhees3282]

I’ve always wonder how humans are probably the most vulnerable animals to diseases that even drinking from lake water could be harmful

[@thend4427]

I wish we were built stronger to be able to kill those bacteria if we ate them

[@blargor123]

IIRC 99.999% of bacteria will not survive our stomach acid

[@deomnibusdubitandumest]

I am not an expert but I think it has to be because of our living habits that has been cumulatively ongoing. We have been living a “modern” life for many many years and our immune system must have been weakened.

[@DRMrThi]

It was estimated that the human life expectancy millions ago was very short (about 30 years), so I don't think it got that weaken but also I agree partially because medicine evolved so much that even people with weaken immune system can survive, so natural selection isn't working that much now

[@TJStellmach]

Humans have to be relatively careful about water quality because we need to drink more water than a lot of other animals. We sweat like crazy, and get a smaller proportion of our hydration from the foods we eat.

[@tonyrome068]

Great job! Answered my questions since I have both in my Bug Out Bag!

[@Delicate_Disaster]

It's so pretty. All the different shapes and colors of the things in the dirty water.

[@JungleLibrary]

Thanks for the follow up video. Would be interesting to see what species of bacteria survived the iodine to add further info on the safety of the water.

[@deomnibusdubitandumest]

Hello, thanks for another awesome video! I have been wondering is it safe to drink water from a spring source in the nature, since I have been taught as so at school nearly at every grade (from my part of the world). Since you have lots of safe water concept in your channel, I wonder how will the non-still water will do.

[@Awesomemelon.]

Id like to say this is one of my favorite tracks you have made great job wih the music and the video I love this.

[@Microscopyenthusiast]

I found your channel via Microbe hunter's channel recommendation list. I am on that list too! I like your channel so far. I will be a regular just saying :)

[@Oscar4u69]

i felt sad when everything died :c great vid tho

[@FionavanDahl]

I watch an Indonesian dental cleaning channel where they're always removing huge chunks of plaque, which are large build-ups of bacteria. Like they built an entire civilization in someone's mouth, until it all gets wiped out with a water pick and some mouthwash.

[@comradekirilov3483]

@@FionavanDahl link? That sounds awesome

[@FionavanDahl]

@@comradekirilov3483 Look for the channel name "Dokter Gigi Tri Putra". They just put out an INCREDIBLE video on April 1 but I recommend building yourself up to that one or all others will look sad by comparison. If these plaques are civilizations, at one point in that video they hold up the Roman goddamn Empire.

[@FionavanDahl]

@@comradekirilov3483 If you're into that kind of thing, I also recommend two earwax cleaning channels, Audiology Associates UK and Durham Hearing Specialists. Anything involving a mastoid cavity (basically an extra carved-out part of the ear canal that regularly needs to be cleaned) is choice.

[@myentertainment55]

Either them or you and your loved ones. Don't feel too sad :) They survived for billions of years 10 thousand times longer than all human like species 1 hundred thousand times longer than our specie and 1 million times longer than our whole civilization. (Dear nerds, please kindly correct me if I miscalculated anything). They probably will be living way way way longer after our kind would be long gone and completely forgotten. Don't feel too bad for them :D

[@domalash]

With each test it might be interesting to test stomach acid or something with similar ph level to see what would survive compared to the filter being tested.

[@atribecalledjudah5436]

A El Monte lake has the perfect water for looking at things that could make you sick. I never would eat a fish from that dump.

[@valenesco45]

Oof this reminds me when I drank water in a lake because I was too thirsty and had no bottles with me. It was clear in my hands but this video reminds me how dangerous and stupid it was. Glad I had no issues after that, gg organism, but as I said I was desperate to drink something.

[@briangindling1266]

I thank you for giving it another try. Im glad you are putting these through the worst case scenario, ive used these tablets many times. Though for the most part outdoors people are mostly getting their water from lakes like you did and streams, not cloudy brown swamps, unless you are in florida! PLEASE do the SteriPen!!!

[@siddharthg8801]

Watching your video after long time, great at always

[@209Twinz209]

Nooooo, not the water fleas!!!!! Lol jk. Great video.

[@MakaOKeAkua]

Would love for you to test the P&G Water Purification Powder that is being touted as the best thing since peanut butter

[@hilohahoma1547]

The critical thing to remember here is that you still need to have some sort of filtering device like many that are great down to 1 micron. Those water fleas can still carry pathogens internally duh.

[@ananassuyu5611]

In one of your old videos I saw spining microorganisms is there a particular reason why they are spining or are they just having fun

[@martythestines]

Any time I see videos like this, I think, mass extinction of a microscopic civilization. May the trillions of tiny souls rest in piece. lol In the name of SCIENCE! Love the stuff my man.

[@loripaulson8807]

This and the previous video on Potable Aqua tabs were very informative. Can you test water under the microscope purified with Potable Aqua Chlorine Dioxide purification tablets? Those are supposed to eliminate more contaminants, including Cryptosporidium. So, it would be fascinating to see the comparison.

[@xXRenaxChanXx]

Makes me wonder how well these would work paired with a basic filter.

[@snowpawzvideos]

Now i wanna look at my fish tank water under a microscope

[@SadFace201]

I don't follow this channel very closely, so I don't know if you have this answered anywhere else. Do you perform replicates of your experiments? I.e. do you have 3 agar plates of lake water and 3 agar plates of treated lakewater? I think that would help people understand the scientific process a bit more. Also, you can count the colonies so that you can show people something more quantitative rather than qualitative. I think it would be very educational.

[@sci-inspi]

Hello, yes I actually do the Petri dish in triplicate and I usually show the dish with an average result. And I leave the colonies unlabeled as far as counts so that viewers can count and judge for themselves. Kind of like a way for them to verify the results themselves.

[@gabrielkawa3477]

Thanks for making this video

[@daniels4742]

Is that lake water safe to drink from what you saw in it? Are any of the bacteria and creatures in it dangerous if I were to drink it? Great video, very nice song. Thanks!

[@sci-inspi]

I am not sure, as I don’t know much about these algae. Should be drinkable after the tablets.

[@leaveme3559]

@@sci-inspi but the bacteria still grew after the tablets.....does it mean it's safe....would our stomachs acid kill the rest or something?

[@Roberto9696-q7s]

@@leaveme3559 yes it would be safe. You stomach acid kills 99.99% of the bacteria

[@M8gazine]

@@leaveme3559 Everything you eat and drink and breathe has bacteria in it, your immune system isn't so incompetent that you'll die from drinking purified water, as long as it's not sourced from the sewers or something. It's less safe than tap water but most likely you'll just get diarrhea. And 'sides, stuff like pesticides (or bacterial toxins like botulinum) are more dangerous since common purification methods like these tablets or boiling are ineffective against those.

[@L7vanmatre]

What about the P&G tablets??? Sure they make the water clearer, but does it also kills the bacteria and microorganisms too??

[@Mairasa89]

Nice ☺️ do water fleas latch onto the body ? What happens if you drink water with water fleas ?

[@sci-inspi]

They aren’t parasitic. They eat small microbes, so they don’t latch onto your body. Nothing would happen if you eat them.

[@209Twinz209]

Maira, we've all probably eaten tons of these by accident. Especially if you've swallowed water while swimming at the lake.

[@olheghtt]

This is good to know, although after seeing a microscopic view of the water I don't think I'll ever drink water again. 😁

[@tofuwiener]

rip water fleas

[@LordSStorm]

I wonder would consuming the body of that flea in the water would be an issue? I mean it might have other things in its digestive system? IDK, i'll definitely be filtering any treated water just to be safe. And boiling it.

[@mr.jaegar8788]

If you don't mind me asking, how do you apply the lake water onto the petri dishes such that the dish is coated evenly? Do you just deposit 100 microliters of water on the petri dish and then swab the water around with a sterile cotton swab?

[@sci-inspi]

I use a cell spreader to spread them onto the dish. It’s a triangular metal tool.

[@13579_dg]

Could you test some of the cheap ceramic filters to see if they do filter out microbes and stuff. I know berkey filters and doulton seem to be the standard for gravity filtration systems but the filters are a little on the pricey side especially berkey and I am very curious if some of the cheaper ones are just as good.
