Walter Lewin Makes a Battery out of Cans and Water
Uploaded by: FreeScienceLectures
Video Description:
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! --- It's Never too Late to Study: http://www.FreeScienceLectures.com --- Notice: This video is copyright by its respectful owners.

| I WILL SELL ANY ONE OF YOU RETARDS THIS SAME SETUP FOR $10,000.....WOW ITS MIND BOGGLING. Also will explain how exactly it works and why it does what it does and prove it!!! For another $10,000 if you are so baffled by it! MASTERS IN DEGREE IN PHYSICS |

| if you watched the martha stewart show this morning ddanvos68 u would understand y he is so enthusiastic.... and it's not that it marvels him it's just that he trying to keep the topic intersting and exciting....i wish i had that in school when i was growing up...it would have made me more interested in science. I'm sorry that u need to be an asshole to show ur intelligence |

| Why are you being so aggressive? I have an understanding of basic physics myself from my undergraduate studies in engineering, but I am currently looking at education and how people learn (MASTERS as you might put it). I think you are missing the point that a lot of education is about inspiration, and that doesn't come from telling people they're stupid. And giving out about people finding things mind boggling, have you ever looked at the quantum processes that underlie all the "simple" things? |

| It is static electricity.. like the same when you shock your hand on the door knob.. 8->12KVolts.. I know it's hard to believe, and it would normally kill you, but there is almost no "AMPERAGE"(Amps), so you get motivation with no mass, basically.. Hoorah, *XD |
