MIT Physics Demo -- Conductivity of Ionized Water

[KakHazhar]

Beautiful.

[lovelplants]

so salt must be kosher huh... great demo.. just don't do experiment like that if your hand is wet.. lol...

[rabbimarcus]

Must the salt be kosher? What if the salt is treif?

[p4ndiamond]

I would use that to beat my meat

[everynameseemstobe]

can anyone explain why the water starts vibrating when he flips the switch?

[JapanIsShinto]

@everynameseemstobe Because he bumped the table while flipping the switch.

[HoneycombAgent]

Don't try this at home!! You could electrocute yourself.

[SpiritualWidow]

That would be an excellent test for deducing which healthy additive to use for conducting electricity through water for ionization. Do you know any of these in the least amounts, which would do best. You used a lot of kosher salt, but how about less and unrefined/unprocessed salt or sea salt?(minerals) or epsom salt in this experiment, and how about iodine (liquid kelp), desolved okinawa calcium (loads of minerals) spirulina or baking soda in what dosages?...lol Guess that might be my prob

[aquapulsefuel]

So why does the atmosphere conduct with lighting. Is there ion up there. Is this a ionosphere ?

[gennaman2bit]

@aquapulsefuel atmosphere is not conductive, but the potential difference between the sky and the earth (sometimes between 2 clouds) can be enaught to ionize the air, so the lightning discharge the potential and the air become non conductive again. In ionosphere there are charged particles coming from the sun radiation and cosmic rays.

[Tagananero]

Sorry for the stupid question... but... Is it 220V right?

A greeting.

[m1ndcontroller]

Maybe they should try using stainless steel plates and Baking Soda next time. Then they'll be generating enough Hydrogen and make this demonstration into something useful.

[ollieoniel]

if you force enough voltage between the plates for it to conduct what will happen to the de-ionized water?

[JayyEZ]

@ollieoniel I think it would just ionize it again into H+ and OH-

[ollieoniel]

@JayyEZ but there is no meterial in the water to take on H+ or OH-

charge.

If your going to comment on a video and diss on it maybe you should learn how to spell or use correct english. "plane" as in the thing you ride in. It should be "plain" water. Just like "break" and "brake" Get it? Good =]

[tcknapp1984]

Thats a cool video! I work in the water treatment field and deal mainly with DI water for industrial applications. It's kind of neat to see one aspect of my profession in action!
