Water alkalizers cost from 700 up to 4000 dollars. Do they have any impact on health? Scientist say manly no, but there are quite a few positive testimonials. 

This Instructable is only for showing the basic concept of how those devices work, so it's not for practical use. The main science in those devices is in measuring and producing required pH and separating water in real-time.

Before you buy this over-expensive machine, you should try at home if it helps you. (For drinking, cleaning wounds or watering flowers).

What you need:
- a knife
- 2 bottles
- a small plastic cylinder
- sponge
- 2 conductive pieces (can be aluminium foil)
- Some copper wires
- Old power adapter (anything from 12V direct current).
- glue

Step 1: Create Watter Bottles.

First take your "plastic cylinder (tube)" and mark a circle on the bottles so you'll know where to cut.
Cut the holes with a knife.
Take the sponge, roll it and put it in the tube. It should go with ease, don't make it too hard.
Put the tube on the hole from one bottle and seal it with a gluegun or some other way.
Take the second bottle and do the same.
When the glue dries, check the seals. Put water only in one of the bottles, the second one should get full from the first one.

I'm not really sure why sponge is necessary. Maybe so the water won't mix, when you'll pore it out.

Step 2: Create Electrodes.

If you have copper wire laying arround or any thick solid conductor, use that. It turn's out, aluminim foil isn't the best idea, because it degrades and then you have small pieces of aluminum floating arround. And your electrode was only for one-time use. If you have rust on your conductor, it will come off too.

For drinking, some use stainles steel or even titanium. Conductivity diffrence between copper, aluminium or titanium plays no role here.

What I did was:
- take two wodden sticks
- wrap alluminium foil around it.

Step 3: Turn on the Power

First take your "plastic cylinder (tube)" and mark a circle on the bottles so you'll know where to cut.
Cut the holes with a knife.
Take the sponge, roll it and put it in the tube. It should go with ease, don't roll it too hard.
Put the tube on the hole from one bottle and seal it with a gluegun or some other way.
Take the second bottle and do the same.
When the glue dries, check the seals. Put water only in one of the bottles, the second one should get full from the first one.

I'm not really sure why sponge is necessary. Maybe so the water won't mix, when you'll pore it out.

Step 4: Be Amazed

After 4 hours:
First photo shows you what water will look like.
The positive charged water (where the negative electrode was) will be fogy.
Te negative charged water (where the positive electrode was) will be clear.

Third photo: pH test. Body pH is about 7-8. Lower values are acid, higher values are bazic.
The foggy water has pH of 13.  -- higher pH is ment for drinking, but not this high.
The clear water has pH of 4 (you can smell the acid).  -- ment for flowers

Keep in mind that those pH are very extreme and i think not suitable for drinking or possibly flowers (even if water wasn't salty).

Forth photo shows what happened with my electrodes (manly the positive one). That's why you shoulden't use aluminium foil. 

Why is one water cloudy ant the other one not?
For what i googled, the calcium distribution becomes uneven, so one has a lot of it and the other one does not. You can let it settle or filter it.

My friend this is all kinds of bad the set up is good but aluminum foil... No! No... And both containers need water. lastly know what the sponge is for the sponge is a &quot;permiable membrain&quot; things like water and electricity can flow through. when the moist sponge touching both sides of water and electrical current it crates interferance like when you put yiur hane in water and feel that slight shock and you know a wireing issue is happening lol the positive and negative charge reach and the water on the positive side becomes acidic from the reaction of the low amounts of negative current and vice versa on the negative side that will create your alkaline water . if you want your water to be potable ie drinkable use platinum coated titanium best/ worse stainless steel but bith are drinkable... out side of these issues its a very good instrucable
<p>how you control the voltage and what level of voltage provided to get different pH </p>
<p>Hey everyone. I have been investigating making a water ionizer but I found <a href="http://www.bawellwaterionizers.com/bwa.html" rel="nofollow">this post on curezone</a> where people are saying that if you do it yourself, you could get metal poisoning if you do not use the proper materials like platinum coated titanium plates. Using something like aluminum foil, as in this example, may or may not be good, as the author stated. I have seen much more sophisticated and promising examples of how to make one than this example above. If you do make one, as I am thinking about, I would like to see someone talk about the conductive material used and prove that it is safe. The water is touching this material, I know aluminum foil is used in alot of things like packaging foods and when we are cooking but with water and electricity passing over it wont it start breaking down? For how long can we use this ionizer with aluminum foil? I have seen <a href="http://www.bawellwaterionizers.com/bwa.html" rel="nofollow">cheaper systems</a> recently for around 600 to 700 dollars, there is no way I can afford the expensive ones like the kangen water ionizers. I am still thinking about making one, but I have yet to decide if I want to invest all that time and effort into something that may not last very long, or may not be so &quot;koser&quot;. I would like to see any reports from people using a home made ionizer and for how long they have used it.</p>
<p>here is the <a href="http://curezone.org/forums/am.asp?i=1271495" rel="nofollow">the curzone post</a> I was talking about, don't know what happened above</p>
The main reason people drink alkaline water is that it absorbs easier, tastes better and doesn't make you feel full or sick after, like regular water can do.<br>It is said to help with allergies. if you search living water you can get a lot of information on it. Dead, or contaminated water tends to be acidic, and cleaner water more alkaline. People shold be alkaline to maintain health...<br><br>At any rate, I do use a water filter that makes it alkaline and find that it tastes a lot better and makes my stomach feel much better. It tastes a lot more smooth, hard to explain if you haven't tried it. My allergies and general health have improved with it... Just saying... not trying to start a big unpleasant debate... this is just my experience with it. <br>
This is a way of putting metal-ions into water? And then you drink it?!<br /> If you want alkaline water, use bicarbonate of soda. The carbonate-buffer system regulates pH in your blood, why anyone (sane) would want to drink this is beyond me...<br /> <br /> Still, as an Instructable it is well done and nicely pictured.<br /> <br /> L<br />
Nothing is put in the water, just rearanged.<br /> Why would someone want to drink that, i don't know. But an&nbsp;acquaintance&nbsp;of mine wanted to buy this device which does that for 1500$ and i wanted to prove him it's not worth the money (because you can do it this way).<br /> My other acquaintance of mine claims this filtered, slightly alkaline water (from 1500$ machine) helps him with his gout. (He drinks the water and cleans his wounds with it.)
&quot;rearranged&quot;<br /> You obviously haven't studied electro-chemistry. I find this a nice and well-pictured make, I like it, But I can't accept &quot;rearranged&quot;. Sell it to gullibles &amp; make your fortune! (no, really)<br /> <br /> L<br />
Well, at least point me to a reference.<br /> From my view, everything that could go in &nbsp;water is electrons, since obviously they don't have enough energy to do that, they stay in electrodes. Current flows only for as long as it can.<br /> <br /> If you mix water from two bottles together, you get back what you started with, so where is this extra?<br />
As far as I understand, Ions get attracted to the charge, which for example with sodium chloride(Salt) turns into Sodium hydroxide in the alkaline side, and hydrochloric acid on the acid side. Very dilute of course, and easily neutralized by the HCl in your stomach, unless you add lots of salt and run for a long time. PH of 13 is definitely too strong to drink, but you might be able to make soap if you could find the concentration. On the commercial products 9.5 is the highest that should be consumed. 11.2 was for topical use. Extra oxygen from electrolysis dissolved in the water should be benificial as well. <br> <br>To repeat, don't use aluminum, and keep voltages on titanium below 14 volts or below. It will degrade faster above that( Titanium dioxide should be kept out of your stomach) If you have the plates close enough and get a laminar current flowing past, 2-5 volts should be all you need. Turbulence will hinder the ion movement through the membrane.
Foggyness is not caused by positive charge or electrons - that's your electrode in there. It should not be drunk.<br /> If you could post me a reference to what chemistry you think is going on in here, and I might have an idea where you're coming from.<br /> <br /> L<br />
Yes, my electrode is in there and may also be small reason for cloudines, but the MAIN reason is limestone (calcium carbonate). Our water comes from the hills and is heavy on it. You may not get foggy water if you're from a city.<br /> <br /> That's also why one electrode becomes white and the other one doesnt after electrolysis (not clearly seen in theese photos).<br />
&quot;The foggy water has pH of 13. &nbsp;-- higher pH ment for drinking&quot;<br /> <br /> Seriously?&nbsp; I wouldn't go near something with a pH of 13, that's drain cleaner levels of alkalinity.&nbsp; Drinking something with a pH of 13 will probably do serious damage to you.&nbsp; Highly alkaline liquids may also make you blind on contact with your eyes.<br /> <br /> Do you have any reading on the health benefits of alkaline water that doesn't come from someone trying to sell you a water alkaliser?<br />
i thought that the lower the ph the higher the acidity and the higher was more basic. ???
.&nbsp; That's what PKM said. Alkaline = basic. 7 = neutral (pure water). You're not likely to run into many substances with a pH much greater than 13 in real life and 14 is the maximum I've ever seen used.<br />
&nbsp;I've used&nbsp;hydrochloric&nbsp;acid with a booster and it had a pH reading of 17, we mixed it in small amount into the fertilizer at the greenhouse regularly.
I suspect it didn't- high pH values represent alkalis, and any pH much above 14 is effectively impossible to create.<br /> <br /> To make a pH 17 solution you'd need to dissolve, for instance, 56 kilograms (123 pounds) of pure potassium hydroxide in one litre of water.&nbsp; Sure it wasn't 1.7 and your pH probe had a missing decimal point?&nbsp; That's a lot more sensible for hydrochloric acid.<br />
&nbsp;Lol maybe it would be missing a decimal if it were a digital meter....<br /> <br /> I know it wasn't 17 pH I just wanted to see how gullible you guys were.<br />
Oh gosh, that is how weak minded people start to repost false things and claim it as eternal truth. Well, since you disclaimed it at the end I guess you don't have to be flogged by a scientific councel.
Heh, yea. Thats about as basic as lye. no way would i go near that.<br />
I was only trying to say, that water which has higher pH from those devices is ment for drinking, the one with lower pH isnt.<br /> <br /> It's stated below in thick. It's not even possible to acheieve such high pH without salt in the water and salty water is undrinkable, so one coulden't drink that even if he tried.<br /> <br /> I will fix the missunderstanding.<br />
I did a reserch about this machines ad they use platinum plates or paladium or titanium if you want to go cheap!!!! other than that it will put you sick!!!! :)
Great instructable! I however, would never drink this water. I have a long history with chemestry and electronics. Never use aluminum as an electrode or in contact with the water. Aluminum has been PROVEN to cause alzheimer's disease. During electrolysis, the process you are describing here, the electrodes will dissolve in significant quantities! (especially light metals like AL) the cloudyness is caused by the aluminum (and some Al that oxidizes in the process) and some destroyed limestone. During electrolysis, most compounds are ripped apart by the electricity. I theorize that the calcium bicarbonate split into calcium (cloudy) and the 'carbonate' created carbonic acid, the same stuff in your fizzy sodas...
