Walter Lewin Makes a Battery out of Cans and Water

http://www.FreeScienceLectures.com

The best physics lecturer Walter Lewin makes another wonderful physics demonstration after having read a lecture on batteries.

The battery he creates has a huge potential difference - 10 to 20 kV!

You'll never believe what it's made of!
It's made of two cans with bottom and top open and two other cans. And then water is let to drip through the two open ones.

After a short period a spark comes up, then another one, then another one.

Do you know how it works? If not, see the free electricity and magnetism video course by Walter Lewin at MIT's OCW!

I so hope he drives a DeLorean :D (with THE flux capacitor, of course.)

THIS IS DARK MAGIC FOR SURE

[urtismcdona13c]

I want this video on my M580 unit.

[jetreschau]

that's free energy we could be using.

I am questioning where the offending forms of remarks are.

[Tplkkvkk]

I wonder if I could use this to power my electric strimmer.

static electricity

looks like a capacitor, not a battery

@quad2004 - fag stop trying to act like you aren't the same child-molester that stalks tesla with 10000000s of fucked up channels, read your original useless-eater paedo-cult post here and recall i already fucking reminded you it's obvious you are trying to backtrack youself when you realised where i was coming from. now go & kill yourself you sad useless cunt.

@JustSomePerson888 "I think someone is getting mad" just some people, i tell ya.

All over a teacher with some intellectual ideas, and me adding my self to the channel update's and making a cute comment. go drink a beer or glass of wine And start reading a good book with non violence. you might feel better. Try a book called "laws of physics"
