I remember watching this as a kid thinking “cooooool”… now I’m a qualified electrical engineer and I still think “coooool” for probably even worse reasons 😂
The insulation was unnecessary, but it helped protect his fingers in case the clip got hot. You need a complete electrical current to flow and touching just one terminal does not make a path. Note that he played it safe and only touched one clip/wire at a time.
You know how this happens, do you? You just go to your supermarket, buying a food and when you come to the cashier's desk you say: "Oh, i almost forgot... and i need 244 9volt batteries" Ordinary day.
When I was a kid I found an electronics store that had a bunch of 67.5V batteries in their trash. They had similar connectors to the 9 V. After connecting a lot of these together they started to arc to the ground and started a small grass fire, which was easily extinguished.
@@wontcreep LOL Mode:Destroy Electronics with HIGH VOLTAGE =Stun Gun Mode It makes me laugh but I think that some people will call "110"(Emergency call of Japan, 110:Police 119:Ambulance and Firefighter) xD
You service smoke detectors don't you? That's the only thing I can think of that would result in that many 9v batteries lying around that aren't completely discharged.
WOW, yeah , I've done that before. One when I was working(too old now) any way we used 22 1/2 volt batteries in a piece of our equipment. I did the same because they had the same connectors. I had about 6 or 8 of them, they were being used, not used up but was still in my VOM/tone, so they had a decent charge. I hook one end up to this metal chair(we each had one in our group room) any way it was during the summer so hooking one end to the chair and the other to the table edge(laminated top metal edge) Well since this guys who's chair I wired came in(quitting time) he sat down leaned his bare sweat soaked elbows on the table. Needless to say he stood up rather quickly. And for some reason he was sorta P.O,ed What I had was nothing to what you rigged up, man you wield with that setup. Man 2000 volts. Man that would slap your dick into your watch pocket. I used to test individual 9v batts, sticking them to my tongue. You need to save some more to see how much voltage you can make. BE CAREFUL. That much juice could stop your heart.
Well.... i was seeing a game review vid... and ended up on how to poop correctly..... Looked in my history, i went like: Game review > game design > car stuff > vsause > more science > physics and biology > assholes paying huge fines with pennies > cyanide and happiness > howtobasic > how to poop correctly Each one of these categories had 3-7 vids in them.... youtube is illuminati. Illuminati confirmed
Lets find out how dangerous this experiment is: We have 244 9 Volt batteries, that makes 2196 Volt. Well, they are not new anymore, so lets round it down to 2000. A limb has a resistance of roughly 1kilo Ohm, that makes a total resistance of 3 kOhm. Current is Voltage/Resistance, so we have 0,667 Ampere. 0,3 Ampere of direct current can be deadly, so this can totally kill you.
Never underestimate DC. I remember having to do daily resistance checks on my body in college to calculate what it would take to kill us at that time. It varied dramatically if you were hung over or not, we were also told to drink salt water some days to see the difference. It was very interesting to see that although 120vac “poke” might only be unpleasant most of the time, but under the right conditions can absolutely end you.
I did something similar when I used to work on medical equipment. We used to replace 9V all the time. I just kept the old batteries and started putting them together until I had around 50 of them. I was at work, so I didn't to anything as crazy as this video, but it was still fun. The most fun I had was tearing them down and seeing how consistently the individual cells discharged. I found several where they did not consistently discharge with one or two really low voltage cells and the rest were much higher.
I'm not sure which is more impressive, having that amount of batteries or having that amount of batteries that come from the same company. You are a consistent fellow.

Finally, someone points out this little factoid! The fact that jersagfast didn't understand that simple little concept is enough to tell me he shouldn't be messing with anything over 9 volts!
No your wrong, DC can charge a capacitor but will not conduct, so all he did was charge it, had it been AC, it would have gone off like an m-80. Just a little AC DC theory for you.
@Fluke Whisperer - Sorry bro, but you're mistaken. It's a low voltage foil capacitor being exposed to 2000 volts DC. The dielectric between the foil sheets collapses, allowing the current to pass straight through. Pull apart an old foil capacitor and you'll see what I mean. Cheers!
He was drawing a big spark at his alligator clip -- with the 10-volt-rated capacitor in series in the circuit. That shows the cap was shorted. It probably shorted a millisecond after putting 2000 volts across it. On a tangent, that bank of batteries got shorted a lot during the video. It would be interesting to have put an ammeter in the circuit, just to see how much current is flowing. Interesting the 10 volt capacitor didn't explode, probably owing to it's high quality of manufacturing and the amount of current going through it wasn't so massive. Yes, no DC current goes through a cap, until it shorts out. Dead batteries have more internal resistance than good batteries. If the dead batteries are removed from the series, the man could get a lot more current, and a lot bigger spark. In fact, the dead batteries acted more like resistors than batteries, and the extra resistance in the series circuit might have saved the man from real injury during the making of his careless video. Adding high(er) current to high voltage multiples the danger significantly. For instance, higher current could cause the alligator clip to weld to the battery terminal as soon as they touch, so the alligator clip can't be pulled away, so high current flows continuously, wire starts to melt. And who knows what other hot, fast, molten things might happen. On a tangent, you can put a fresh 9 volt battery on your tongue. If you're a true electronics hobbyist, you should be able to recognize a fresh 9 volt battery that way, and recognize if it's dead, and with a little more experience if it's somewhere in-between, no voltmeter required. It's also another way to get acclimated to non-dangerous currents flowing through your protoplasm, that a little shock ain't no thing.
Dang, even seven year later, and this is one of the best videos I've seen on youtube. If you bought this many batteries new (energizer) it would cost around $2440 @ $5 for a pack of 2...
As a kid sitting in 5th grade class, I was playing with a "dead" 9V battery that was among the other junk in my desk. While the teacher was talking I inadvertently touched the 9V terminals to my tongue. I let out a yell that made the entire class jump.
That is very impressive ! It reminds me of the times I used to go to Alaska Surplus in Spokane Washington. They would have outdated 67 1/2 volt "B" batteries for a dime each that hurt the tips of my wet fingers. I dropped $3. of my allowance and went home with a sack-full. They all snapped together as well. I didn't have a meter in 1967, but I could throw a hissing arc almost 3 inches. Dad din't care because I was just in his way since 1951. But I was told by a friends dad 2025 volts at that high of amperage could have killed me in a heartbeat.!
Amazon item B00NZ9C4C0 is a 67½ V battery. According to one of the reviewers, the original battery was carbon-zinc. The one selling on Amazon is an alkaline, which is certainly a superior replacement. 67 volts is probably too high to test by putting it across your tongue. Last time I heard about B+ batteries, the only ones available were old surplus. I guess Demand required more production, and here they are. But if I had an old radio that needs 67 volts, I'd build a power supply before buying too many batteries.
@@whatsascrewdriver5572 Hello my friend, In my early teens, having 3 much-older sisters, and a cold father, I was left to fend for myself entertainment-wise. When I was in junior high, my bike route to school took me down an alleyway that was behind a telephone switching building. I would always stop and paw though their 4 trashcans and would find all sorts of relays, wire and gizmo's they would discard. One day I hit the jackpot finding 4 batteries about 6-7 inches cubed with about 20 push spring wire clips on the top. I could get any voltage I wanted from 1-1/2 up to 90 volts out of each. They were full when I found them and I had a lot of fun for over a year. When I opened one it was full "c" cells. Maybe someone else will remember this, but about 10 years earlier, about once a year a man from the phone co. would come to our house, and opened a box near our telephone and replace 2 big cells 1-1/2 volts each. He gave a set to me to play with. Keith.
jersagfast: Just a few batteries... Fire department: A few? How much is a few? jersagfast: Just a few dozen... Fire department: Really?... jersagfast: Ok, fine, I used just a few 244 of them...
Amazing that Somone has done this!! Next time I recommend making the cathode the crocodile clip(or better - insulated screwdriver) and anode the battery terminal as the cathode gets much hotter when arcing.
On your seems-nothing-happen capacitor: Actually in this case the capacitor is broken through by the high voltage and behaves like a conductive wire. So in a word in this case your batteries are short circuit. Without any external resistive load, all the power is transformed into heat inside the batteries raising the temperature VERY QUICKLY when you are staring at it and wondering why "nothing happens". If low quality batteries are used, you are only waiting for a serious explosion of the battery group.
or if the capacitor is an electrolit condensator, it has a minus and a plus leg. try to put it in the other direction of the polaryty. it will blow i up like a popcorn (with bigger sound)
+Piotr KOW You, sir win the worlds dumbest 10 yr old trying to look smart award. Please meet me in the place idiots go to die to collect your award. Thanks and congrats
ZeidGho Yeah, I've personally been working on it but I'm not quite there yet. I've made a couple AAA batteries during a 14-hour sleep but they only supplied maybe 100mA.
These all say industrial on them this guy totally took used batteries from an industrial plant that he works at. I use the same batteries at mine. They throw them away after a period of time regardless of use.
