One other suggestion since you seem to have a deadline... I just rubbed an empty plastic Coke bottle, which is made of vinyl or some other plastic, against my jeans pants and the bottle became charged. I also rubbed it against my sweather and it became charged by that too. All kinds of things work.

I have lots of problems with humidity in my town, like you say charging an object even with a HV power supply charge does not stay a lot.

Regarding the what happens with a positive charge, you're right. Regarding the humidity, the issue is with the charging and not the electroscope at all. So I guess the electroscope can be in a humid room as long as you rubbed the two objects together in a dry room, or charged the object in some way that didn't have a problem with humidity, like an electronic high voltage power supply. Glad to hear you like the videos! Thanks for letting me know.

Wow! I'm so happy to hear that. I remember participating in science fairs myself. Congradulations!

Cool! I'm always delighted to hear when it works out!

Glad to hear it worked. Thanks for letting me know what fixed it.

In this case it's not the size that's important since the area of the disk and blinds that faces the electroscope terminal are the same, although the disk has grooves in it so it actually does have more area. The material is also matters. They're both vinyl but they may also have coatings on them since they're different colors. If you look at my triboelectric effect video (see link in the description below the video) you'll see some materials become more charged than others too.

oh man, I had to do a project in the school about this, and this video was perfect to show me how to build an elctroscope and how does it work. It helped me a lot!! you have won a subscriber!! :D (sorry for the bad English, I'm catalan xd)

Nice and clear simple and quick to make. 2 notes If the leaves touch the glass they transfer a charge you can see this at the end of the video the last few frames the leaf magically jumps to the jar wall and back in to equalize charge as it bleeds off the curly end into the air. This is why the scope appear less sensitive as you use it in the video. You can ground the leaves by touching the probe with your hand. you may need to ground the glass where it touched which is why on some versions you see rods between the leaves and the sides. and with very high voltages sharp corners/edges/points bleed voltage which is why on most of those old machines everything is tube and ball looking

Thanks again! I glad your enjoying these videos.

Wonderful presentation. Thank you very much. I just made one to show our children... We appreciate your time and effort!

You're welcome. I love hearing when it's used in real life, so thanks for letting me know.

School science project. Learning tool for learning about electrostatics. Useful tool. I do a lot of work with high voltages and I use this to detect if something is charged and even to test whether something is positively or negatively charged.

Oh! Cool idea! I just tried it and it works. The leafs separate. I also did a test using the electroscope and induction to see if the screen is positively or negatively charged. The screen is positively charged. I sense a video in the making :). Thanks!

Check the foil leafs in the jar to make sure they can move freely. It's also possible the problem is not with the electroscope but with the charged objects. If the air is too humid then it's harder to charge them. Maybe the air was drier the first time you did it. Also, try many different objects. Also, if I use a drinking glass as the object, it works only the first time and then I have to clean it thoroughly with soap and hot water because my hands put grease on it, stopping the charging.

Thanks for the feedback folks! Making it helpful was what I was after. This is definately encouraging me to make a complete Wimshurst machine explanation video I've been planning on.

Glad to hear it. Have fun!

You're welcome! I'm glad I could help. Thanks!

Thank you sooooo much this helped me alot as i needed this for a physics project

Yes, as long as it is lightweight and can move freely. The force causing the foils to separate isn't usually very strong, depending on your charged object. There are other metal foils at hobby and craft stores (brass, copper, steel), some candy wrappers, aluminum from soda cans. The foil must be electrically conductive metal and make sure the place where the foils contact the hook that they hang from is electrically conductive - no coating of any kind.

@5MrPurple It's optional. It's there only to hold the wire in place as it goes through the cover. You can use tape, glue, a tight fit, or whatever you can come up with in order to support the wire. Heck, the wire can even go through the hole in the cover and then be bent flat sitting on top of the cover, in which case you don't need to support it at all. Maybe just tape it flat to the cover so it doesn't move around.

Thanks for clarifying. Sounds simple enough, I'll give it a try. -Steve

@ThePunchClock You're welcome, my friend.

Yay! It almost always is the charging that's the problem. Super glad to hear you're project worked out.

@LookhinAweSome My pleasure!

I am a student from Greece. Great job! I'll try to make this!...

I agree. A lot of people have used it for science projects and got it working just fine. For other charged objects you can rub a plastic coke bottle or rubber balloon against your hair and bring the bottle or balloon near the electroscope terminal.

@SquishyRhinoes A paperclip would work. Any bare, uninsulated wire, will work.

You're welcome! Glad I could help!

Yay! It works! :) Thanks, I'll keep the videos coming.

thank you for making this video! im planning to make this for a science assignment at school and i was wondering if there was anything else i could use for the coper wire and also is there any object you could suggest to use to charge the electroscope? thanks

@swordswordswords The vinyl is non-electrically conductive so the charge won't conduct away to your hand in that direction, regardless of your skin conductivity. Good suggestion re the dryer.

@Saskachewan I just undo the tape. It's easy to put back on and I never have to open it up anyway. But using a twisting lid is a good idea too. Either works fine unless you use a tape that works only once or is difficult to take off. As for the effect of the strong field, just don't put the terminal too close to the charged object. The electric field strength weakens with distance. If there's a reason you can't do that then use heavier or larger foil. More mass means less effect from the field.

@vestprend1993 The ends of my wire were sharp so I put a little round bit of solder on them using a soldering iron. I could just have easily sanded the ends round. I probably didn't need to do this anyway, just a habit from working with high voltage a lot, so I don't think that's your problem. Can you give more details of how yours is made.

Thanks! I'm glad it helped.

@semih007gmailcom Done already :). See my triboelectric effect video, there's a link to it at the end of this video and in the description.

Just to anyone watching it in the future: you get a huge charge if you rub the vinyl against your hair.

I got it from household wiring, the wire in our walls here in North America. I have a roll of it since it's nice and thick and I find it useful for projects. Find out where your electricians buy their wire. Here we can find it at Home Depot as well as specialty stores. A metal wire coat hanger will also work. Just make sure you scrape off any coating where it will be in contact with the two foil leafs.

Thank you very much for this video,it was my homework to make an electroscope and I am really thankful 👌👌👌

It's an insulator because it doesn't conduct electricity. E.g. copper is a conductor - electrons travel through or along its surface easily. But electrons don't travel easily through or along the surface of cotton. But due to the triboelectric effect electrons can be removed from the surface of cotton if rubbed with vinyl. And electrons can be deposited on the surface of cotton if rubbed with glass. In both cases it's not conducting electrons, just collecting or losing them from its surface.

omg this is a life saver because i have extra credit in science and i really need it and she told us to make this and write a paragraph of how it works and this video is perfectttt!!!! omg thank you so much!! :)

@amarben123 I'm not sure I understand your question? The wire I used was 14 gauge (AWG). I took it from some household electrical wire that I had lying around, the kind used in our walls here in Canada. Thicker wire does exist. If you have a Home Depot nearby, they would also have 12 gauge (smaller number means thicker wire in the American Wire Gauge system) and probably all the way to 8 gauge. If this doesn't answer your question, please ask again.

@XGalaxiX Yes, you can use something other than a copper cable. Aluminium foil in the shape of a pencil should work. The foil leafs do have to be hanging fairly loosely so they can separate easily.

@meliknida You don't have to. I used it because it was an easy way to hold the wire in place.

@RimstarOrg Thanks sooo much!!! It was too humid. You were a big help!!!!

Man you are awesome!! I love your vids!!!

@ComboSmasher Instulated means there's a coating on the wire the doesn't conduct electricity. Example: a plastic coating on a wire prevents electrons from going onto the wire. The only parts of the wire that really have to be uninsulated are where the aluminium foil leaves touch the wire. It's optional, but it's handy if the terminal part of the wire (where I made a spiral) is also uninsulated. That's good if you want to touch it with something to put or take off electrons.

@NGUpremier You're welcome. I'm sure you'll have no problem with it. Cheers.

@TheKiller5456 You're welcome. Glad to help!

Oh. When I searched for "BSA Nuclear Science Merit Badge", the only mention of electroscope in the requirements was this: "Build an electroscope. Show how it works. Place a radiation source inside and explain any difference seen." Americium-241 is a radiation source, which I happen to have because I took some from some ionizing type home smoke detectors. Oh, well. This is a super cool experiment anyway so I'm glad for my misunderstanding! Good luck getting your badge. Looks like lots of fun!

My pleasure, and thanks.

Exactly, RimstarOrg. You can use a marker or highlighter to color half of the strip (or color both halves, red/white, red/black, whatever). Place a charged object near to the glass without touching it and watch the paper react. The trick is to poke the center of the strip onto the needle in a balanced way. Careful as too strong a charge can push the paper off the needle. Also glue the eraser to the bottom of the glass to make it portable. Although I have not tested this portable version myself.

Thanks bro! :D I had to make this for school and this video is really everything I need! Your awesome! :D

Any stiff wire will do, as long as the part that the foils are touching is bare wire and not coated with anything. It has to be foil touching metal. You could take apart a metal coat hanger but make sure to sand off the area that the foils touch since I think coat hangers have a coating on them. A metal paper clip is another choice. Look around and see what you can find.

I'm glad you like it :)

You're welcome! Have fun with it!

@shanism88 I used the thin one. The thick one may be okay too but you want the foil to be as light as possible so that even if the repulsion force is weak, it'll still work.

No, the electroscope doesn't need to be airtight at all. But the jar is useful for keeping wind or moving air from disturbing the foil leafs while you're making a measurement.

No, I think I was just wondering if anyone else here was working on the Nuclear Science MB too. It's pretty fun stuff! One of the requirements was that I had to build an electroscope. But I don't think I know anything advanced like the stuff you just explained! You're quite knowledgeable!
