A while ago, i made a video about a device that was just basically a spray bottle that you plugged into usb and it turned salty water into hypochlorous, acid or diluted, bleach cleaning agent and at the same time i ordered a few different ones from ebay. But i didn't want to make too many videos about the same thing so now it's time to take a look at another one, and this one is called the household we'll use disinfectant generator. Five minutes use salt and water with our procult. You can make disinfectant by yourself five minutes: excellent, sodium hypochlorite generator 99.99 disinfectant.

When we open it up, we find a set of instructions in chinese and english reasonably acceptable, english and the device itself. Obviously i chose the pink one. Did i choose a pink one, or is that just what i got, but it is a pink one. I probably chose it as being pink as the usb connector.

You can see through the side electrodes inside which i'll take this apart later on. I don't know if there's any active electronics in it, we'll find out when i take it apart, but you get the unit and you get a scoop of salt and it basically says in instructions put water into a glass for every 100. Milliliters. Add one scoop of salt: i've measured the scoop with table salt and the scoop actually measures three grams, so they suggest two percent salt.

This is actually making a three percent solution and for comparison uh to this disinfecting or water sanitizing solution. I got some of these little tablets that are chlorine, water purification tablets. I think they're chlorine are these chlorine. Oh one moment, i'm just going to check this.

Ah, yes, it does release chlorine. Its ingredients are sodium, trochlear, seen otherwise known as sodium dichloroazocyanurate lovely and when you dissolve one of these 8.5 milligram tablets in one liter of water, it makes a density of, but it gives about five parts per million of chlorine. I exaggerated that i dissolved one in just uh 100 milliliters, which is a tenth of a liter, and i dipped a stripping it because i've got these chlorine test strips here and the level is extremely low when you dip the strip in there's a very slight color Change keep in mind. This is 10 times as the strength that it would normally be and when compared to the chart, it comes in about 2.525 milligrams per liter, so it'll be a tenth of that so 25 to 50 milligrams a day or so will effectively be 2.5 to 5 milligrams.

A liter, okay right. I should put that strip out the way that is a reference. It's very weak. It barely smells bleachy right.

Tell you what let's begin the test. So here is a little scoop. I'm going to add the one spoon where's, a teaspoon. I've not got a teaspoon, so one scoop of salt to this i'll, just use this to stir them to mix it up.

I don't think it needs to be all dissolved anyway, but that water is now completely undrinkable and to see how much current this unit draws. I have a power bank and i have a plug-in meter. So let's do this. Let's uh get this cable untied and i shall plug it in to this.

Nothing will happen, probably because i honestly don't think there's much in the way of circuitry ammo dunk it in the water, but i'm going to time it i'm going to put it in for five minutes um and then once it's been in for five minutes, i'm going To measure the strength of that, the salt is not all dissolved. This is not really surprising the current it said it would be an amp. Let's start the timer start, it's only 300 milliamp, it's drawing. I can see the bubbles coming out, though uh.

So they said, it'd be an amp, i feel cheated, but maybe this is good. No sure it's in here now what's in here and we will open up later, are two electrodes. I get the feeling, i don't think, there's a resistor in here or anything but we'll find out. We open it, but uh.

There are two electrodes and it causes an electrolytic reaction where it kind of the salt. The sodium chloride in the water reacts with the oxygen hydrogen and you can see it bubbling here in the bubble: smeared. Well, let's zoom down, so you can see it bubbling, let's just zoom down, so you can see absolutely everything. This is what this is.

What it's supposed to be about here, um and since we're more interested what's down there, we'll focus down on that and right now maybe yeah swamping it out, but we can actually see what's happening now with the power right table uh, so it separates that. Can i smell it? Oh yeah, god that is so bleachy smelling that is making a very, very bleachy liquid right table. I'll give it it's five minutes at the 300 milliamps and i shall return and then we'll stick the strip in and we'll see what strength of a stuff we've got with this test and see you know, what's a result we get. I shall be back in three minutes and 30 seconds and start so uh current is up to 400 milliamps.

Let's turn the power off swish this about a bit in here. So that's it had five minutes. What strength are we going to get? I think it's going to be quite high. Am i going to be dripping stuff everywhere here? Yes, i am.

Let me just grab a bit of paper towel. I didn't think this through. Did i? No? I never do it's not a surprise. So here is our uh liquid.

Oh, that just smells like like a swimming pool, exploded, let's put the strip in that's a lot stronger. Okay! So let's see what this comes in at actually on there, i would say it comes in at somewhere between 200 to 300. Probably close to 300 milligrams per liter, okay, that's quite strong um and i'd guess that if i gave it another uh five minutes, it would yeah. Let's give it another five minutes so i'll, just bang it back.

In again i mean by the magic of youtube. We can do this so in it goes again. The bubbles are fizzing out of it. Let's give it a shake to make sure that uh it's making connection, let's start the timer again and uh yes, i'll, be back in five minutes and the next test.

Five minutes later, let's turn the power off again. It's up to 400 bullets waving around about 400 milliamps. Let's do another test on this and see what the concentration is now, so i shall uh swoosh around with this tap it on the side, put it over on the paper towel, which is in place now, and i have to give it another swirl just because i Feel the need to swirl it for some reason, just to make sure everything's mixed in. I shall dip.

Is this a new bit? Yes, it is a new bit of strip. I shall dip this in even darker, oh yeah, let me show you the original strip. This is closer to the hold on i'll. Just let i'll let you guys decide i'll.

Let you guys decide here by focusing up there, what do you reckon 500? That would bear outrage, wouldn't it that is kind of doubled the strength, and there was the original one that i did the first pass through. So that was the two to three hundred. I think it's actually lightened a little bit since uh, probably because the bleaching effect of chlorine - but i would say, yeah this one's in the region heading in the region of 500., so uh it does produce a fair concentration. Now the question is what, if i was wanting to use this to actually sterilize drinking water? To me, that would mean getting one liter of water, putting a pinch of salt in and then maybe testing it just to see um.

Oh that's going to be quite tricky to test. I shall maybe right give me one moment: i'm just going to do some experiments, okay, random, wild experiment, time. I have put two pinches of salt into one liter of water. That's that much! I'm gon na drop the electrode and see how conductive it is it's showing about 50 milliamps, and i can see the stuff bubbling out of that already.

I'm not sure if you're going to see that it's also doing its best to float out the water um. Are you able to see that i shall move over to that side? No, it doesn't want to move over to that side. It just wants to do its own thing, so i'm going to leave it for five minutes in this level of water. So, let's start the timer again uh and then when i come back uh i shall taste the water and see if i can actually taste the chlorine in it.

I'm not sure if you can see that i'm going to move this to the middle of the shot and actually, let's get a focus target at round about the same height which will be about there and i'll move this to the middle of the shot. Uh. Put that about the same height, it's really not want to play ball, because it's floating about, partly because it's filling itself up with gas and the next part of this experiment after tasting this i'll zoom down this. This is just to show you.

There are bubbles coming out of it. Can you see the bubbles? Yes, you can see the bubbles coming out of it, so once i've done this i'll taste it and then after that, i'll just take this thing apart. I've already noticed that the little pink rubber band thing may be covering a screw because well i've not lifted it, but it is a sort of flexible rubber sleeve that's been put over, so i shall be back shortly and resume so this is still drawing about the 35 to 40 milliamps, depending on how many bubbles are in it, uh i'm not getting a huge smell of chlorine. I wouldn't expect it.

There is a tiny. Ah, let's try the stripping it and see if it changes color at all. Ah, no color change, but then that's what i got with the first test. I did uh with the tablet dissolved in the in one liter of water.

I'm not sure, but can i taste the chlorine? Oh i'm just going to taste it not sure. I think it may require a bit of experimentation to determine how much how long you'd have to leave it in the water, but it certainly was doing something right. Tell you what i'm gon na take this out the way before i spill it everywhere, i'll be back in a moment all cleared up. Let's open this up.

Does this thing come off it does it's a sleeve? Is there a screw? No there's not a screw. It's just a little rubbery sleeve. Is it holding it together? So the point of that experiment was really to suggest that perhaps in the event of an apocalypse you might be able to sterilize drinking water. Oh this does just unclip apart.

That's quite nice! Is it just gon na be two electrodes straight on, let's zoom down for this, for the for the reveal, but in the event of a super mega apocalypse, maybe you could improvise uh water sterilization two of those electro plates. These have some fancy coating on them. Oh one of them has the fancy coating. You can't just use stainless steel or aluminum, because uh there's a certain.

The reaction is quite vicious, so one of these plates may be some special coating on it. People say platinum, but i'm not sure they'd be using platinum and cheap products, although i suppose it's possible, this plate could be coated. Platinum and they've got the polarity in the exact way for it. Uh.

Is this going to split open any further? I don't think there's going to be any circuitry in this. Is there i think this. This is chewy they've, actually kind of molded that in there i think, tell you what then we could improvise this um. I shall just do a quick test.

What can i do here? I shall do a quick test i'll just pause moment of momentum. I'll do this, because i don't think it'll be that quick. One moment please test complete there, there's no circuitry. It is literally just the five volts being applied across these two electrodes.

There are specific distance apart. The coated one is connected to positive and the uncoated one that just looks like just bare metal, not sure what metal is it's not easily attracting hold on i'm just going to scratch that i'm going to scratch it with a sharp probe one probe. Is it aluminum not sure that is, it could be stainless, not sure it's certainly not attracting a magnet um. Now nothing really magnetic about that.

Although there are some stainless alloys that are slightly magnetic and some that aren't, it could be stainless and that other one well a coated stainless in the case of that one, although i do noting the edge, is like they've cut it from a sheet that has just Been coated in the surface and the edge is fairly sort of dirty in the sense, it's just a bare metal edge in that it's not got the coating all the way around. So i'm not sure that is the coating they've put in it, but it is one apparently optimized for creating the hypochlorous acid uh when you apply a voltage across this current flows through the salty water so yeah. I guess ultimately it's interesting to know this. Just in case somehow, in the end, in the future that you somehow find yourself in a scenario that you need to create some sort of hygienic way to treat water, including drinking water, but uh interesting little thing.

I can't immediately think of any use for other than that camping. Maybe that would be quite handy, but there we go that. Is it it's the little uh? What do they call it again? They called it. The household will use disinfectant generator.

It's your little usb powered one with no circuitry at all, just the two electrodes in the usb supply in a fairly neat little container, and that is about it, but interesting, well worth testing.
