How in the world did a glass of water shock anyone? Welcome to the crazy story of the invention of the Leyden jar: a powerful electric device that was invented by accident!
We've got electrifying hundreds of people for the King's pleasure and a bunch of masochistic (and sadistic) adrenalin junkies with some really difficult names to pronounce! Check it out!
You can find more information on the history of the Leyden Jar from:
Benjamin, P "A History of Electricity" (1898) pp. 514-536
Heilbron, J "Electricity in the 17th and 18th Centuries" (1979) pp. 313-320
Priestly, J "History and Present State of Electricity" (1767) pp. 84-97
Correction: Leyden is in the Netherlands not Germany. Sorry
As usual, the music in the beginning and the end is from the fabulous Kim Nalley.
ps. if you want to make your own Leyden jar it's easy, just take a bottle of water and stick a metal stick in it (I used a metal skewer). It works even better if you add some tin foil on the outside! That is it. To charge it up you can rub a tube with cloth or fur and then rub the tube against the metal stick. Or, you could do what I did and make an electricity machine with a plastic lid on a drill rubbed against rabbit fur. Remember that the outside must be grounded (connected to the ground). Have fun :P

As far as I know the Leyden Jar is named after Leiden in the Netherlands, not Germany, ( Leyden being the contemporary spelling) where Musschenbroek was born and university educated. Musschenbroek did work in Germany but that was at the university of Duisburg before he returned to the Netherlands to work at the university of Utrecht.

A common mistake is to think that Dutch means Deutsch (German). Van Musschenbroek was a Dutchman, so a citizen of the Netherlands working at the university of Leiden. It is the city I was born in. Also the city where the Pilgrim fathers stayed for a while before setting of on the Maflower. So you Americans should remember !

Nice video, but two small things to keep in mind: Leyden, Germany is in fact Leiden (or Leyden in old spelling), The Netherlands. Also, once you get electrocuted, you're dead. I don't think everyone you say who was electrocuted, was actually electrocuted.

I was wondering if someone would comment on this. Electrocution is death by electric shock. A friend of mine has a favourite intro at the beginning of his electrical safety classes: "Welcome to the electrical safety class. First up, who here in the class has been electrocuted?" and sure enough people put their hands up. :)

5:00 : Leiden is a Dutch and not a German city, and Musschenbroek is actually pronounced "Mush'n'brooke". We Dutch speaking people like to make things unpronounceable: it's one of those things that defines us, I guess. Your French is excellent, by the way!

Guericke's experiments with the sulfur globe were published in 1672, so I consider him the father of electricity, and the most underrated scientist/inventor. If it wasn't for this simple electrostatic generator made of sulfur, nobody would come up later with the Leyden Jar, and the Volta battery later.

They're getting harder to find, but I had thought of collecting about 50 of the Cathode Ray Tubes from clunky old TV sets to make a 1 Million volt capacitor. Each one can easily hold 20,000 volts with very high capacitance. I have all sorts of high voltage experiments that would be very expensive to do otherwise. It would take up a lot of room though. Guess I'll build my lair by the lagoon 😂

Franklin didn't "discover" electricity. We knew about it but just didn't understand it at the time. What Franklin did do was study it, learned where it came from, and figured out how to control it enough to eliminate lightning strikes from damaging buildings. Another big surprise, he did not fly that kite in a rainstorm. He flew it before an approaching storm to prove that electricity came from the air and that he could collect and guide it.

Amazingly, he did get the body to move and even open an eye! Fascinating but a little gross IMHO.

Modern knowledge about electricity cast doubt on the mechanism you described for storing charge in a capacitor. There are very interesting experiments when a charged flat capacitor is disassembled and then assembled with the replacement of some parts. Some of these experiments baffle even highly literate people. For example, this was done by physics teachers who run the KZfaq channel GetAClass in series of videos "Where a charge stored in capasitor".

When I was at school in 1981, our school textbooks gave us enough history of physics for us to understand how people came to understand these ideas. Some part of the process by which the scientists arrived at their conclusions was given to us, without which the textbooks would be mere information, not knowledge. But I find that the present day school textbooks in my country are cursory and in a great hurry to convey the information and move on. I recently volunteered to make a set of video lessons in the local language, and finding their textbooks lacking the proper sequence of historical development, I am trying to connect the dots myself. Encyclopedia Brittanica is a good source. apart gthat, could you suggest any other good reference?

Very nice, except, Leyden neither professor van Musschenbroek were German, but Dutch. Dutch is used for the people or the language of Holland (The Netherlands). Leiden (or Leyden as it was spelled in the past) is a city in Zuid-Holland, one of the provinces in th Netherlandswith one of the most famous universities in the country. Maybe because Dutch and Deutch (for German) look more or less the same caused the misunderstanding.

Ewald Georg was one of Prussia's von Kleist family. The von Kleists include military men (quite a number of field marshals), literary men, and philosophers. At times the same von Kleist is all three. During the Nazi Era two von Kleists were closely involved in the Hitler assassination plot and one paid the price. Another field Marshall von Kleist was notably humane towards during WWII's Russian campaign. He was a humanist. After the war the Russians wanted him turned over for alienating Russians from Russia by being such a nice guy. Only the Russians could dream up such horrors. Said von Kleist died in Russia.

You would probably need a distilled spirit, e.g. vodka, which has a higher concentration of alcohol. I doubt it will work with something like beer. The water in the liquor (see previous reply) acts as a conductor (easily ionized) and shorts the circuit. Think of a flambé or saganaki at a Greek restaurant. The liquid in the capacitor is still only water which is also acting as a conductor which helps to distribute the negative charge over the inside wall of the jar.

Will make a video on it as it was super easy and worked well but here you go: Took the lid from a 5 gallon bucket, drilled a hole in the center, secured a screw in the hole with bolts and washers. Used the same screwdriver to spin the lid while rubbing it with rabbit fur (although I think wool will work). Then, stood on a plastic stand and held a large aluminum disposable cooking pan on the lid. Presto chango, a $6 Van de Graaff! Hope that helps, tell me if you had any problems or how it worked.

I have a 240vac fan motor that runs full strength on just one of the two phases, i.e., it runs on 120 vac. How can this be. What am I missing here. And I used to think that I understood basic home electrical wiring. I can really sympathize with Musschenbroek.

@@vk2ig Yes. Ever since the start of Federal Aid to Education, the quality of K-12 education has been slowly spiraling downward. By the late 1990's my son's High Scholl physics book had already been dumbed down to an alarming extent. And, to make matters worse, they had stopped teaching it in metric. What a colossal missed opportunity.

Here something odd: water has a relative dielectric constant of about 81. Mica is only 4 and the other dielectric materials are about this range. So why water not used in the making of capacitors? 🤔 You turn the water into a gel very easily to, so that makes it easier to work with. I used these silica crystals that I bought. They're food safe too.
@vk2ig
@vk2ig 2 жыл бұрын
You'd need distilled water. And it wouldn't be able to react with anything (e.g. the material in the plates of the capacitor), as otherwise it would form an ionic solution where the ions can easily move and thus conduct electricity. Transformer oil is used in some capacitors - it doesn't react with the plate material.

@@vk2ig thanks.👍 I forgot about oil. I wonder what the dielectric constant of oil is? 🤔 You also reminded me that water dissolves almost everything over time.👍👍 It might start off pure water, but it won't take long before it isn't so pure anymore. Maybe stainless steel would work? 🤔
