Water & Electrodes? Con Or Not?
Posted: 12-06-06 12:12pm

I'm not sure if this was the place to ask this as it has to do with both doctoral smarts and science smarts.


Some guy came over to my house to test our water clarity today, and he hooked some device up to 3 different glasses of water. (i think he called it some kind of electrode device? I missed that part)

one with tap-water, one with the bottled water we drink, and one with the water he brought.

After using this device, the tapwater became litterally black, it looks like a bunch of broken up pieces of dirt, or crap.

The bottled water turned with a little bit of orange sand at the bottom, and his water had nothing out of the ordinary.


This guy wants to charge us some monthly fee for a filter, which is tempting considering what we saw in the water weve been drinking...


What i'm asking is if this guy is a con, and if what he showed us was some form of trick, ive heard and I know alot of con bull crap, but I cant pinpoint this one.


Any help or comments are appreciated

thanks

Alright. First off, I live in memphis where they put a bunch of chlorine in our water to hide its crap. Anyways...
He did electrolysis.

He most likely took an electrode made out of a material that decomposes on contact with certain chemicals.

Think of it like chrome plating, they take the material, put it in a special liquid that it reacts with, put electricity through it, and then the stuff tries to go from the positive to the hot electrode.

If you don't live in a clean country, I personally would opt for something. Not necessarily what he had to offer, but some sort of filtration system for the tap water you drink (if you do).

Bottled water should be fine if thats all you drink. That stuff is processed.

Remember that cooking a substance you put tap water doesn't necessarily get rid of all the "bad stuff". Take the new carbon nanotube/buckyball scare


also, please note this are the words of a high-schooler, so i'm not going to guarantee anything I say.
