I instantly wondered if you could charge multipul plastic cups with one setup then use the stored power on one cup then disassemble it and put the next one in and use the energy stored on it so on and so forth. As long as you dont wipe the charge off them.
"And here's Jeremy to help me" "NONONONONO NOT AGAIN. . .PLEASE SIR, I PROMISE I WON'T DO IT AGAIN . . .IT WAS TOMKINS THAT MADE ME DO IT . . . . . " (Great video btw, nice and clear. )
Great. The Leiden jar disassembly experiment is always a great one to demo especially when you have put a good amount of charge on it! Good that you show students this 'capacitor' as it rarely sees the light of day in modern physics teaching.
Very nice video, I am currently working on doing an instructional video on constructing a homemade jar but am in the research stage to make sure I understand the concept as much as possible before moving into the next step. I didn't really learn anything new from this video as I've already looked into this quite extensively, but I think you did a very nice job on it. Good quality and quick, thank you.
Why is the exterior metal positive and the interior metal negative? (Or vice versa.) Answering that question would go further to explain matters. Also why do many Leyden jar constructions use water inside the jar?
Remember that electric charge is present only when negative electrons are separated from positive protons. However the charge is generated, you are left with an abundance of electrons on one surface and protons on the other, thus negative and positive. You can charge a Leiden jar, or most other types of capacitors, with either polarity connected to one side or the other. If you touch the inside element with the positive charge, the outside element always becomes negative, and vise versa. The water or other fluids inside early Leiden jars just served as the inner conductor, and can be replaced with conductive metal. Aluminum foil is a cheap and easy material for making the plates of a capacitor, and a sheet of plastic kitchen wrap or even waxed paper between them makes a fine dielectric.
The energy is not in the charge separation, which is proven by the fact that you can touch the two metal conductors together and there is no discharge (with the insulator or dielectric removed). The energy is stored in the dielectric itself, in the form of an electric field. Though an alternate theory is that the energy is stored in the dielectric as a distortion of the internal magnetic fields.
".. very much like a capacitor." A Leyden jar is precisely a capacitor, just an early form. The jar is composed of two conducting elements (the metal cups) separated by an insulator (the plastic cup). This both describes and defines a capacitor.
1:45 how was his body the souce of outside charge??? Aren't these metals suppose to have equal but opposite charge? What if the vande graff generator produced more charge compared to his body?? Also how did his body even produce charge? Sure it's a conductor but like ehhh???? I am so confused someone please explain!!!
Long copper pipes grounded hold charge, instead of the charge in the atmosphere getting so large it needs to spark, instead it naturally grounds. Lord knows why no one is trying this
You said it yourself, "charge can't move on an insulator". What, then allows "The charge" to manifest as a useful means of electrification? Charge your diaelectric glass, plastic or distilled water, it will hold millions of volts, just keep it away from most metals. Redo the experiment and travel with only the Dialectric material to reveal your experiment. You'll always get a spark. This experiment has been done, if not hundreds of times, thousands of times. Conductive and Non Conducive materials are now inverted. Explain?
Can ANYONE explain WHY this one works without "Water" inside of it like literally ALL the other Leiden Jar designs I see on RUclips? Like for example this funny twit in this video: ruclips.net/video/xjW-isgOijs/видео.html As you can see like ALL the others he uses water with "Salt" to make it conduct electricity, they ALL seem to say the water is "Required" for a Leiden Jar to work, yet the one in this video has no water! WHY & HOW??? In the link I just gave he also claims a " van der graaf generator" can NOT charge a Leiden Jar, so WTF??
The setup acts as a capacitor, a capacitor is made up of two conductive metal surfaces (or plates), in between the two metal surfaces we place a dielectric material(plastic in this case), which will get charged and store an electric charge when the conductors/metal plates are electrically charged. In this video you have the layered materials [metal cup + plastic cup + metal cup] so, conductor + insulator/dielectric + conductor. In the other videos using water you have [metal foil + plastic cup/bottle + salted water], so conductor + insulator/dielectric + conductor. Its the same principle, its just that, for the inside of the cup/bottle, water is used as a conductor instead of a metal cup as in this video.
I really appreciate the fact that you can disassemble this one and the explanation that the majority of the charge is on the dielectric.

This is a fantastic explanation. Thank you!
Nice demonstration. Can you please explain why you touch the inner cylinder with an insulator whereas the outer cylinder is touched with barehand.
Where can I buy the magic stick?

What a fascinating voice controlled Van de Graaf generator. Made by Tesla?

@@neodos he did ... earlier on the video 😊
will any metal work for this?

Thank-You very much for an excellent explanation.
Thanks For the Explanation. I came for the business of Physics.
Whats the thing tube called when you charge a capacitor? 2:08
Fun Fly Stick
it's naughty of you to not credit the musicians!!! please can you tell me who it is cos i really like the sound. Thanks for the video -

Arbor Scientific's Dissectible Leyden Jar is available at:

Great video an explanation !
can you charge it with a battery
You the guy from webassign?
What’s that thing he’s holding
Discharge tongs
1:45 how was his body the souce of outside charge??? Aren't these metals suppose to have equal but opposite charge? What if the vande graff generator produced more charge compared to his body?? Also how did his body even produce charge? Sure it's a conductor but like ehhh???? I am so confused someone please explain!!!
His body is conductive, making a path for the electrons to leave the outside metal piece, giving the metal a positive charge.
Great job man
Why does intro and outro music have a frequency ring that's obnoxious to the ears? Otherwise muted with subtitles it was good.
is there any way to harnes of lightning electric ?
Long copper pipes grounded hold charge, instead of the charge in the atmosphere getting so large it needs to spark, instead it naturally grounds. Lord knows why no one is trying this
Really good videoo!!!
Wimshurst should not have been a failure, hmm. I assume you should have connected outer plate of the jar to the outer plate of the opposite jar.
Wow. Amazing
excellent
forget leyden, how tf did you summon the van de graaf generator to turn on by voice lol

i love it are famliy went to go see it
you did good
"Very much like a capacitor", it IS a capacitor.
Julius sumner brought me here with his charge experiment

what is the name of the 'light' at the end of the stick at 3:58? thx
That is a xenon flash tube.
