15 Kilovolts From Water and 4 cans!!!

I really enjoy Walter Lewin's physics lectures and demonstrations, there should be more teachers like him. Here he is creating a battery out of 4 cans and trickling water. He is able create around 15 kV (kilovolt). I had to see this one to believe it. Pretty cool stuff.

You can see some of his lectures on electromagnetism here and find more free science lectures here.

I realy enjoyed his lecture. I like this teacher. He has been my favorite for sometime. I could be bias to the subject but he is a good teacher.
