I have those same purification tablets but I never use them now I know. They're more effective in clear water versus dirty water.
L
@Ray 'not a fed' Epps, flowing water, rivers, streams, and springs not a stagnant pond.
the other brand tablets I have states it takes 60 mins to have purification effects, so Idk why this one is 5 mins
@lemon9.9 where did you get the 5 minutes from? He literally said the instruction was 30 minutes, and that's what he waited also.
I wonder if it works after 1+hrs? Thank god I never needed to use my emergency water cleaning tablets.
I am fairly sure you're meant to strain the water through a cloth filter before treating it, I do bushcraft, and one solution is to run it through a shemagh or bandana, the microbes can hide inside the larger dirt clumps which defeats the point of the iodine tablets. Multiple filtration steps can also be done, such as filtering through stones, moss, sand, then a cloth barrier - this will keep a lot of protozoa and debris from getting through the filter, and make the water easier to clean with iodine tablets.
Thank you
Thanks!
He did it as stated in the instructions🤷♂️
I'm fairly sure you're meant to watch the video where he says exactly this.
@@boogiebomber2191 No. No he did not.
Your microscopy channel is one of the very best. It's edifying and relaxing at the same time. Keep up the great work.
This is similar to the cool stuff an awesome science teacher would pull up during class to help explain their lessons to the students. I sincerely hope some of them have found your content and done so! This is fascinating.
I've said it once long ago and I'll say it again. You having a live stream with relaxing music and your microscope zoomed in on microscopic life would be great to watch.
Despite being a year late, I agree
@@theradjo5355 he pop up in your recommendation today too?
@@aliciatiller Yes!!
Always filter first and then use tablets as extra security. I do a bunch of back country fly fishing and have to get water from various sources. I always use a tablet after filtering from streams, etc.
love the voice over, much better than the captions in older vids
I actually have these tablets and I have always wondered how much microbes it will remove and now I know how good they work so in a survival situation I will find the clearest water because that’s what they work best in, thanks for the experiment man!
By the way, thank buddy for whatever you are doing..🙏
You are doing a great work..I always suggest your channel to my friend who have forgotten the school biology lessons 😭😀

I used these exact tablets while hiking with clear flowing river water. The next day I felt like I was dying.
The key is to get running water, either stream or lake to stream, rivers are kinda iffy because you don't know if they have nuclear waste in them. FYI! Also it's best to carry a filter straw with you or water filter system, which doesn't contaminate the water that you are drinking. Also you can write down on a piece of paper and laminate it of bleach drops to liters of water or gallons for that fact. Keep it with you just in case you are out in the woods drink something horrible and start to get a little sick to your stomach at least you can take the paper out and look at it to remember what the right amount of drops to water you need in an emergency.
Thank you for testing. This is good data and also great hypothesis 🙏🏻
would love to see BRITA filter under the microscope :3
Why do the the screw threads need to be moistened? Does this create a better seal? And why would a better seal be necessary if you are going to open it immediately after anyway?
i go hiking and now knowing that these wont do a thing for me thank you
it's funny 'cause I subd after watching the boiling dirty water experiment, then watched the lifestraw one (because I got a couple of those) and the came to see this beause I bought this as well... love this channel!
Sci-Inspi
Could you maybe do a vid where you rub your hands really fast together, to produce that characteristic burnt smell, and then collect a sample of the first layers of the stratum corneum from your hand, to see if any skin cells were actually burned off?
This is my hypothesis on what happens when we rub our hands as such;
the friction generated heat does indeed burn skin cells, but only the superficial, first layer of cells in the stratum corneum.
So the superficial layer gets burned off, but because that first cell layer is so thin, the heat is quickly diffused into the rest of the layers and the air, so it only feels warm, not really hot.
Iwasnt able to find any info on this myself, so Id appreciate your imput in form of eaither vid or comment.
Cuz Im really curious abtbthis, Ive wondered since I was a kid lol
My tattoo artist told me that hands and feet are difficult to tattoo without fading because they shed cells faster than anywhere on the body ......don't know if this is true or not.
@@bmphil3400 Inside your mouth as well.
Some dumbass in school got his name tattood on the inside of his lower lip, it faded very quickly.
@@bmphil3400 capillary action pulls the ink deep into the tissue so I don't think skin shedding makes much sense.
I’m about to be tent boondocking it in Alaska in the next month or so until I “make it” there and I just wanted to say thank you because I was looking at those tablets on Cabelas as a way to purify water.
These do work, although the water has to be pretty clear. I did a follow up video showing it. I also did the lifestraw and the Katadyn hiker and they also work well.
@@sci-inspi I watched your “boiled water” test then you followed it up with the life straw, seemed like a pretty good setup; only thing I’m not sure of is how good any of this is filtering out chemicals such as fluids from cars and other man made chemicals that may be present in the water. This is of course strictly for survival since I no longer plan on drinking water straight out the river unless the method used is safe to do so. Happy Holidays.
For chemicals you would need a filter specifically for that. Although if you are in natural areas that aren't polluted, you should be fine. Happy Holidays to you as well!
These are the older style tablets, I stopped carrying them years ago as my backup. Nowadays we have chlorine tablets in packets that don't introduce the same weird tastes and are more effective. These are what I carry as my backup purifier with my first aid kit, where these little bottles don't fit very well, And there's risk of spilling/ruining the whole bottle.
Could you please name the brand? I'm looking forward to buying some!
Really enjoyed the narration in this video
What happens if you add ethyl alcohol to dirty water? Does he disinfect it?
Woooow! So glad you did this video! I will be getting my sister a filter because those tablets are a no go!
They do work, but in clear water. You can see that in part 2. Water Purification Tablets, Part 2
ruclips.net/video/mXXhvquXsd0/видео.html
@@sci-inspi Hey, I did watch that video but in an emergency there is no guarantee you’ll come across clear water. I’ll get her a water filter in addition to the tablets. Thanks again!
When the water is cloudy you are supposed to double the dosage.
I would be interested to see if the effect would be improved with more tablets.
See the end of the vid; why would you want to drink that?
This is a really interesting experiment, definitely need to put the water though a filter to get rid of turbidity before using iodine tables to be safe
Try using a water purification treatment with a flocculant included. It reduces the turbidity and then chemically treats the water for a much cleaner water. Chlor-floc is one brand. P&G purifier of water is another one.
If I might suggest. Try finding a flocculant like aluminum sulfate (styptic pens or rock salt deodorant tend to be good sources). See how flocculation alone improves the quality of the water. If you remove the solid particles in water. You remove their food. They want to stay near their food. That’s the idea.
I’ve used a lot of disinfectant and cleaning methods over the years and probably like iodine the least. It’s hard to beat pump style ceramic or engineered fiber filters they’re usually capable of at or below 0.2 micron and pared with say chlorine bleach or iodine can filter and kill everything. I e even tried UV bags which basically just leave filtered water out to be irradiated by the sun in a special bag and nothing is as fast or trustworthy as the pump filters, other than maybe a battery powered filter. In a real pinch I’ve filtered water through quite a few layers of cotton (a shirt folded over many times) and that was able to get the big stuff out and it was iodine after that. Iodine tabs were good as they are solid but I’ve also used bleach, I’m quite small concentrations with good results, maybe a cap full to a gallon if I recall, with a little more in rinse water after washing dishes. I grew up in the back woods and have been outdoorsy my whole life without ever getting sick from food or water (knock on wood), though I have known people that have gotten sick.
This was a wonderful experiment and I'll be conducting my own; but in the case of water filtration through gravel, sand and charcoal.
That is fascinating!!! Thanks for the experiment!
How about the uv light to disinfect water?
Water you'll encounter is going to have a lot more than leaves dying in it.
can you do a microscope of tap water and see if any micro dots thingys exist
Ive used those a ton, but I wont be using them again.
Yeah, get the water from a flowing stream, filter it, then use the iodine. Murky warter needs whole diffrent method of treating
There is difference its said in the instruction it will disinfect drinking water never said dirty forests or pond water
The percentage of bacterias are different.
Video Request: Effect of Chlorine Solution on Contaminated Water :)
City water goes through multiple steps. I would 1st use a cloth, 2nd a Sawyer and 3rd add the tablets to the filtered water.
Hi can you pls. test the P&G water purification packs? thanks
would this be effective against toxoplasmosis for cats who use the toilet? would one of these in the toilet work against any possible oocysts?
Better with filtration methods, such as Sawyer filter for dirty water, doesn't kill viruses though, so can use disinfectant tablets as a secondary purification method.
For anyone looking p&g water disinfectant works the best for dirty water to get it clear then you can use iodine.
How about plain old chlorine? That should wipe things out in seconds 🤔
You should've used the P&G coagulant, I've always wondered if it's really that effective.
Suggestion if you haven’t already: Do a dirty drink from a milk container and put it back in fridge. Microscopy it a few days later.
The iodine was used up. That nasty water is going to have a much higher demand. Cleaner water would have a iodine residual after the disinfection, hence the second bottle the remove the iodine taste. I manage a water treatment plant, fyi
Thank you for the confirmation. That is what I suspected, although I wanted to find some scientific evidence to support my hunch, which is why I cited that WHO report.
Nothing beats boiling it. If you can pack tablets you can pack a fire starter and some sort of metal container.
I used to use chlorine tablets. How effective are those?
Awesome. I loved your experiment and your conclusion of it. Thank you
Thanks! Chlorox?
I wish you tried doubling the dose
I hopee you also tested same water with double amount of tablet
Chlorine based tablets may be more effective.
You only need nine drops of chlorine to purify 1 gallon of water, my old house had a pond and we use that water for drinking we ran it through a sand filter and we ran through an idolizer our water did taste a bit like iodine, but it took very little to purify enough water for a household, I think maybe these tablets I cut so much that there’s very little iodine in them. 🇺🇸🇺🇸🇺🇸%
How about taking a mask and seeing exactly what they do and do not catch? Would be interesting to see!!
lifestraw then those tablets? Wonder what would happen.
Nice! Can you put a wound under the microscop?
Thanks for making this video
Could you do a video on the Big Berkey water filter? They actually have an add on your page claiming they remove 99.9% of virus’s. They make a lot of claims, but independent tests are hard to come by. Thanks for these videos
Viruses*
Viruses can't be seen on visible light microscopes like his ones are
Great stuff! Thanks for the knowledge!
The bacteria said: “Mhmm iodine!”
Can you upload it without the painful background noise?
Try using a whole bottle of the iodine tablets, or way less water for the two tablets
No, that would make a person very Ill. The proper amount of tablets can cause nausea vomiting or diarrhea on it's own if you use extra you're almost guaranteed to get sick don't use extra tablets just filter the water before using the tablets
@@CHRISTisKing197 Good to know. Would still be cool to see the results of examining the water
yeah I mean, the instructions on the tablets don't say to use it on swampy dirty water. would you drink water that looked like that?
The instructions state only fresh drinking water, but I made the water really dirty and nasty to test the tablets. While they didn’t work too well in this situation, boiling and lifestraw eliminated nearly all microbes. It serves as a good way to compare these bacterial water purification methods.
Do you think that bacteria and viruses and microbes are sentient beings with some level of consciousness? Or..do they just kind of "exist"?
Would have been nice to see tap water on a petre dish for comparison. Also, bleach.
Have you ever tested these tablets in a bottle of water that already still yet has a high ppm, parts per million?
Thank you.
I like those tabs! I have a question if I have expired water in bottles can I still use a purifier like a berkey or potable water to retain it? Thanks 🙏
Can you do P&G purifier of water plz??
Huge shouts to you Sci inspi... what a fantastic channel you have. I've been Stuck all morning watching...
I loved fermenting plant juices and feeding em to roots... I've played with lots of beneficial bacteria an microbes.... but never owned a scope.
My favorite ferment to create would be lactobicillius serum... a prebiotic for plants.
Those arnt ment to sterilize water, its for stabilizing clean water for long term storage.
I don't get why didn't you just use the water after a day or so to have clearer water.
it's like the movie 300 when the tablets go in there with an army of bacteria in there 😂
Whats the best purification to use? I seen the life straw video and that seemed to be a great option but how do you get chemicals and stuff that the filter doesn't filter? Is our best option just boiling to is there another option for say an SHTF situation
Boiling will only remove a small number of high vapor point chemicals like alcohols and other chemicals more volatile than water. Chemicals that are less volatile won’t boil off your water will boil out before they do it also won’t remove heavy metals like lead, chromium, and cobalt. If you had no other choice and you really had to drink absolutely contaminated and filthy water your best bet would be to distill it in two parts. The first part of your distillation would be heating the water to around 200° Since water boils at 212°F anything that boils off at that 200° number would be a volatile chemical then you could dispose of that then boiling the actual water itself at 212 would give you the purest water you could have two problems with that method though one distilled water doesn’t have any minerals or electrolytes in drinking it will slowly leach the minerals, electrolytes, and vitamins out of your body so you’ll need to reconstitute it with salt potassium and other minerals you can get packets of them to turn your distilled water into mineral water
The second problem is the possibility of azeotropes. Azeotropes are a phenomenon that occurs when you have two liquids that one mix together boil at a lower temperature than each of the individual liquids themselves like ethanol no alcohol we drink ethanol boils at 78.4c but a mixture of 95% ethanol and 5% water boils at 78.2c that means that you can never totally get all of the water out of the ethanol the ethanol that you’re going to drink will always have 5% water remaining. Of of course you would be distilling water not ethanol but the point stands your water can form azeotropes with other chemicals if you were dealing with unknown chemicals and unknown azeotropes you could theoretically distill your water and still end up having a Huge amounts of various chemicals in the water itself it’s really impossible to know unless you specifically know what chemicals are present in the water and whether or not you can actually remove them. a lot of heavy metals can be filtered out but you would have to know what they are and what the smallest micron presenting the water
@@samuelw4492 Thank you for the response man this is something I will be looking into more now that I have something to look at. Water purification is something I feel would be good to educate on whether you are hiking for a long period and need more water due to dehydration or its the one-off chance that it's a SHTF situation.
Please make a skin sample
Can you try blended stuff?
What do you mean by blended stuff?
@@sci-inspi Things that went to a blender! ,just to see for example is there any difference in the cell wall of a lettuce that is normal and one that got "blend"
Thank you for this video
Looks like we got ripped off
Please use a chlorine based disinfectant tablet.
It's pronounced "pote"able not "pot"able, and it means something drinkable.
At least now I know to throw away mine. Or at least filter the water as much as I can and then boil it.
you have to filter the water for the tablets to work
Please do the same experiment but using POOL SHOCK.
That’s a great summary and a good experiment
Yeah, I think just very crude filtration with gravity and then through some cloth could change results drastically.

Hey man, is the paypal link broken?
It works fine for me.
will liquid iodine for wounds work just as well for water
Nice ! Good to know for future use
so youre basically god to these microbes, and the table as COVID 💣 Intresting
Oh shit I was not ready to hear a voice on this channel
Could you maybe also try micropur? That is the type most readily available in Europe
Sorry, but isn't the requirement for pre-treatment filtration common knowledge. Maybe not, but I've always seen this requirement very clearly highlighted on the tablet packaging.
I've either used a Millbank bag, or made an improvised filter using any fabrics to hand like socks, shirts, cloths etc etc.
Can you look at the powder that was featured in Mark Rober's videos? I don't remember the same of the powder but it'd be cool to see it.
Can you see Curd under microscope ?
Are you telling me a Hypothesis does NOT have to be in a ‘if…then…because…’ format?
what the hell i just bought these . i didn't do my homework. sad.
They work, just not on super dirty water. I made a part 2 to show that. ruclips.net/video/mXXhvquXsd0/видео.html
Try the PNG water purification powder
What about Sodium Chlorite pills?
