SHOCKING Science with a Leyden Jar

SHOCKING Science with a Leyden Jar


Hey guys welcome back and thanks for joining us today on The King of Random In the history of inventions, one of the greatest of all mankind is the ability to harness and control electricity. Some of the old experiments that taught us how electricity works are really incredible. In 1745, an early version of a capacitor was invented by Ewald G. Von Kleist, when he accidentally gave an electric charge to a medicine bottle. A year later a man named Pieter van Musschenbroek came up with the same invention while living in a city called Leyden. His version of the invention became a lot more popular and was named after the city and is now called a Leyden jar Its most basic a Leyden jar is an insulated container with an inside and outside holding opposite charges When something bridges a connection between the two the charges equalized and it creates an electric shock the purpose of today’s video is to learn how to build our own Leyden Jar charge it up using electricity and then discharge it to get that electric shock the materials we need for this build are pretty Simple we need a plastic bottle some aluminum foil a nail and some tape to build up our static charge We’re also going to want some paper towels and a length of PVC pipe this one’s about three feet long the exact length isn’t important. We’ve gathered up all of our supplies now Let’s get started. You can use most any type of plastic bottle for this experiment I prefer the type that has straight walls because we’re going to be wrapping aluminum foil around the bottle and it’s easier to wrap evenly With straight walls than if it has a lot of curves in it First empty your bottle Next let’s remove the label from the bottle it might work Just as well with it still on, but I think it gives it a cleaner look if we take it off Next let’s tear off a piece of aluminum foil approximately the same length as the straight portion of our bottle Let’s see if some of the glue residue on the bottle will stick to the foil oh It does that’s brilliant If your bottle doesn’t have sticky residue you can roll it up. Just the same way It doesn’t need to be stuck to it like that. We have a little bit extra foil. I’m just gonna trim it off With our foil wrapped around our bottle, let’s secure it in place with a couple of pieces of tape There you have it we now have a nice conductive coating on the outside of our Insulated bottle fill your bottle almost all the way with water leaving a gap at the top of about an inch or two 100% pure water actually won’t conduct electricity but most tap water has enough minerals and impurities in it that it will but just to be Sure, let’s add a pinch of salt to make sure that our water conducts electricity very easily It should only take a pinch you really don’t need much There you go with the salt mix it into the water We now have a very conductive liquid inside the bottle now the last step in building our Leyden jar is to drive our nail down Through the center of the bottle cap so that a portion of the nail is sticking up above the bottle But some of it is also sticking down into the salt water You can see that the bottom of the nail is submerged in our salt water This will allow a good electric current to flow from the nail to the water And just like that your Leyden jar is built This is now a device that for some time can hold an electric charge unless something conductive Connects the nail to the foil with our Leyden jar complete it’s time to charge it up using static electricity a very easy and Consistent way to build a static electric charge is using paper towel and PVC before we start using our PVC Let’s clean it off using some high grit sandpaper to be sure that it’s free of any oils or dirts or residue You can see that the sandpaper is so fine that it doesn’t even actually take off any of the printing on the pipe But it is removing some extra residue Now take a piece of paper towel and run it along the length of the PVC pipe quickly this will help build up a static electricity charge I Don’t know if you can hear that but It’s building up a charge fast All right with a static charge built up in our PVC. It’s time to transfer it into our Leyden jar We’ll do this by just passing the PVC pipe very close to the nail it Sounds like if you rub the balloon on your hair Or if you’ve ever had one of those old see our TV screens right when you turn it off makes that crackling noise I’ve now charged up the PVC and put that electricity into our Leyden jar five or six times now So I think it’s time for a test to see if it will discharge The nitrile gloves are gonna be too much of an insulator So I’m gonna take them off try grabbing the foil and then touching nail to see if I get a shock oh I got a shock just from the foil That’s not how it’s normally supposed to go, but it’s probably good side. We’ll find out I know that Was a little bit a little bit of a shock And I jumped too hard just because I was nervous about whether or not it was powerful I think it was probably not a good idea to keep the PVC pipe so close to the bottle it might have still had some interference with the electric fields and it also is possible that I Had just inadvertently built up an electric charge in the foil itself And then when I first touched that it discharged a little bit, so let’s try this again All right, and it shocked me again wonder what’s going on here. Well. I’ll still try touching the nail Yeah, it still got me again. It is working to some extent I’m able to hold the foil and I get a zap when I touch the nail But it’s also zapping me a little bit when I grab the foil in the first place So I’m going to try taking the foil down by a button It’s just in case the static charge from the PVC is also jumping onto the foil as I pass it next to the nail I’m gonna try and move it away from the nail a little bit Okay, let’s try charging this up again There’s five charges and this time when I grab the foil it’s not doing anything to me Let’s see what happens when I touch the nail oh That was definitely a bigger shock all right I
think what’s been happening is the foil itself has been building up something of a charge and since I’m standing on the ground when I Touch the foil that charge runs through me But when I hold the foil every time as I charge it it keeps the same charge as me which is a greater difference? From the charge inside the water that makes it so when I touch the nail it give us a bigger shock Last time I charged it five times this time. I’m charging it ten All right Here goes nothing let’s see what it does to me Girl oh Boy, okay So last time I felt in my arm that time I felt it in my whole body like it went Like I felt it in my other arm and down through my legs and just still there’s big ole jump alright That’s pretty fun. It doesn’t actually hurt. It’s just like a pulse that goes through you alright well That’s working pretty well something else. I want to try though I’m gonna turn down the lights and see if we can actually watch the electric spark jump oh I Saw it I hope it was on camera. That was another good Joel tiny little spark It didn’t have a big gap to jump over, but it was there something I’m going to try to see if we can make it a little visible I’m going to hold another piece of metal before I touch it Instead of touching you directly with my fingers it might jump the gap a little bit better that way Good Well, it didn’t really jump the gap I still had to touch the foil to the nail I think but I still did see a spark and when I touch it with my finger it looked like a yellow spark touching with The foil looked like a blue spark no idea what the difference is there we go We’ve charged up our Leyden jar using some PVC and paper towel But I want to try and take it to the next level in a previous video we shattered a plasma globe while it was running Now we’re going to try using this plasma globe to see if we can charge up the Leyden jar with it when this is turned On if a piece of metal gets near the bulb you can still see that purple spark showing up I’m gonna try touching it with my glove oh It’s like doing pretty much nothing well. It’s still getting the spark though, ooh It’s starting to heat up just took my finger, let’s see if it It doesn’t really give you a shock it gets warm But it doesn’t like just this is a lot more of a feeling of electricity well Let’s see what happens if we touch this to our Leyden jar well, it’s sparking kind of like when I touch my finger to it I Don’t know if that’s building up the charge or not Let’s just let it go for a second and see what happens. Oh, it smells like ozone Wow, that’s kind of powerful. Well that seems like plenty of charging to me see if it did anything No shock from touching the foil Nothing nothing whatsoever I Thought it would do something. Oh well well whatever electricity is coming out of that It doesn’t seem to charge our Leyden jar So I think the best way to do it is just stick with the PVC I was kind of hoping you would be like a quick-acting charge. Just this is full oh well Whoa my favorite thing to do is you get this bottle charge it up pretty well about 10 passes Then you get a group of people have one person hold the bottle on the aluminum foil and have everyone hold hands in a circle Then you have the last person in the circle touch the nail and everyone in the circle will feel the jolt run through them It’s pretty entertaining There you have it now. You know how to build yourself a Leyden jar Which is an early type of capacitor a capacitor is similar to a battery except that instead of discharging its electricity slowly? It dumps all of it at once This Leyden jar capacitor is made just by using a plastic bottle some aluminum foil held on with tape and a nail It’s then filled with water with a little bit of salt added for conductivity and charged up using the static electricity generated with PVC and a paper towel This is something you can easily build an afternoon and have fun experimenting with or you can just use it to prank people and tell Them to touch it and see if you can get them to do that without knowing what’s gonna happen They’ll be in for a surprise We tried charging up our Leyden jar using our broken plasma globe because it does discharge Electricity in some form but apparently it’s not anything that will charge this out if you know of a good experiment that you can do With a Leyden jar let us know down in the comments, and we might try it out Thanks for joining us for this project today, and we look forward to the next one talk to you then This might be a very dumb experiment I’ve charged it a little bit just in three passes, and you see what happens if I lick the mail It’s a tiny little Zap on the surface of my tongue didn’t do much. I don’t really want to do much more than that it sounds painful Hey guys. I hope you’re having a great day. You are awesome You are appreciated, and I know everyone over here on my team is really grateful for you Thanks so much for choosing to watch and support our videos. We’ll see you in the next one

    A plasma globe puts out high frequency AC. You need a high voltage diode between the plasma globe and the Leyden jar. Otherwise, it's just rapidly charging and discharging the jar.

    you should have used a multi-meter before touching , would have been interesting to which extent of how many miliamps the capacitor held from all that pvc rubbing , the reason you still getting zapped from the foil is that some of that current is passing on the plastic which is basically the same polymer type chain structure as the pvc pipe that currents flow through , use a more inert container like a wooden jar

    I think I know what's happening when you touch the plasma globe to the leyden jar I think the plasma globe isn't charging the layden jar I think the layden jar is charging the plasma globe instead of it being the other way around so maybe if you touch the plasma globe to the layden jar why the plasma globe is plugged in then after that unplug the plasma globe an see what happens when you touch the plasma globe with your finger then
