Electrical Arcs at 1,750,000FPS - The Slow Mo Guys with ElectroBOOM 

bro 💀

He should’ve expected nothing less. It’s the price of working with a legend like you!

@UCxZHI-uH9LZ_OygPLFHH0BQ go eat dirt.

Well, you get ionisation switches that go into the MHz repetition range, used for some military radar systems, so expecting less of air is no problem. Also some gas filled tubes would be quite happy oscillating at over 30MHz, so the gas ionisation must be capable of being quenched as fast.

The legend of comedy and knowledge 😂

(phantom) pain

yea the pain

sweaty palms that a blink of eye can miss the frame in 19 hr video!

I was wondering why you were sifting through all of those frames manually :D

@@anoobis117 why are we still here?

I’m impressed by his knowledge, yet amazed at how often he almost kills himself just making a video. I aspire to be just like him someday…

@Auschwitz Soccer Ref. you seem very mature with that name

@Auschwitz Soccer Ref. there's some irony here

​@AuschwitzSoccerRef.you're the 12 years old kid

The reason he can mess around so much is precisely because he is so knowledgeable. He knows exactly how far he can take it.

ok

That’s just stupid lmao, it’s freaking electricity

@Edline Nannencia no one waited you to be born

Now they just need to pack up that camera and go to Sweden. I want to watch the new monstrosity by Mattias Krantz light up.

That's still 620 km/h, incredibly fast

What great point. I thought how awesome it would be for them to capture that in a wide view then remembered the needed brightness for indirect illumination that goes into the camera 💀💀

Strange? I always thought light (and electrons) travel at 300000000 m/s (in a vacuum). So even in air light is still quite a bit faster than 170 m/s.

@@edwardcarpenter8277 pff xd time in refrence to the cameras footage

I don’t know about you but those numbers look off. If you replay the clip from 1.75 million fps to just 25 fps, that’d be 70,000 times slower than real time. Doing some calculations… the speed of light would just be going about 4.29 km/s in that clip, which is still incredibly fast to our eyes. If I’m wrong, do call me out.

Tis the job of all us electrical engineers

Has Tom Scott been zapped yet?

@@sedontane not yet to my knowledge at least but we will get him

I mean just looking at the difference in lab coats, Gav clearly chooses who goes in the lion's den.

like when he dropped in on the halfpipe and almost shattered his ankle! what a badass

@@zhou_sei His wrist, right?

Totaly Grian with Mumbo Jumbo

Yes it is

New student here, I thought a capacitor was an open? How come a capacitor fills up? If the impedance makes it effectively an open, I get how the current goes through the short, but if the short leads to another capacitor (open), how is it a short path? Thanks (Again, just took circuits 1 so I might be missing something)

@@wildavis3016 You are correct, in a DC system, a capacitor will eventually behave as an open, once it receives enough charge to 'fill it up'. Once full, the capacitor denies any further charge, acting as the perfect open (infinite impedance), forcing all the current elsewhere (down the line to the next sets of capacitors). However, if there is sufficient enough voltage potential between the positive and ground/negative sides, the the voltage can actually break down a medium (in this case, by ionizing the air between the two discharge nodes). This arc acts as a very brief short, which totally drains the capacitors, resetting the system. This is why capacitors are only rated to certain voltage limits, as exceeding these thresholds will cause this same breakdown within the capacitor itself, resulting in the wonderful "pop" we all know and love Mehdi for.

@@Deper91 ok that makes sense thanks

Fact of the matter is, it *must* be a cascade effect, but much like glass breaking, propagates so fast that it is all but impossible to see the behavior. The giveaway here is that all the gaps have to "close" for anything to jump out of the output (as these are series switches)... But clearly one has to reach potential before all the others, if for no other reason than there will be slight differences in the gaps. My guess here is that it just so happened that the end gap was the closest, but it could have been anywhere in the chain. Once the first one goes, the others are immediately "over" and fire off in an order relating approximately to the gap sizes. This may actually be random in appearance, *IF* one could record all of the time in between. Obviously this is extremely difficult. Once they are all bridged, the output goes hot and an arc is ready to jump if something is close enough. You'd therefore see the output spring to life after all of the chaos in the gaps is resolved and they are all conducting.

@Kynan That's only true IF there's no reactive components present. Sorry buddy but been doing this a LONG time and know how it all works. 🤷‍♂️

Mehdi: IT IS MEHDI

Is it mehdi?

@@levstoffman6238 Yes✌

i thought he said frequency and not power

i have never thought about that that’s cool

Yeah, they've talked about that before. Unless someone else does a lot of slow mo of themselves it's probably not even close.

In terms of sheer length of footage, maybe. Turning 2.7 seconds into roughly 2 days sure helps.

If you count each frame as one photograph, he definitely is.

Y’all beat me to it.

Amazing

Nice 👍

Yes

Super

The shopping center is very crowded with many other types of items loaded..

Mehdi*

Best guest appearance on the channel if you ask me. And they've had Will Smith and Tony Hawk.

It really is a joy to see someone that both knows and loves what they're doing.

He's always a fun feature to see, his collab with LTT and static electricy was great as well!

They have slowed light down to a crawl. Look up the MIT 1 Trillion frames a second.

I was also thinking, maybe they should automate finding the frame with a computer algorithm. The algorithm doesn't need to be very smart, just "Find all frames that are 50% brighter than the average" would probably be enough to detect the sparks.

It's crazy how much physics can be checked/confirmed from using cameras to see this- though as we see, you do need the cameras that can hit the nanosecond/billion frame per second range to play with lightning, (electricity), just like observing light propagating. We REALLY need you ELECTROBOOM and the Slow Mo Guys to get together and just check/mythbust things about both light and electricity- at the nanosecond scale range. It's a shame equipment that can keep up is so rare lol, at least at this point in time, you need other than a phantom to get to that nanosecond scale range. I really hope we get more opportunities to see these happenings like this resonant frequency example- it's one thing to know it's happening, it's another to be able to "see" fast enough to witness these nutty aspects of physics

@@CD4017BE Well they did, you just have to remember to bring the cable 😅 (See Gavin's comment above)

I was really hoping to find you here.

Now, if Electroboom and you and Steve Mould and Gav and Dan were all in the same place… We would have a real blockbuster science video, …and probably a new discovery of science.

Is he Jewish?

I like when how 3 of them meets

You mean *you* didn't realise? Because I have seen thousands of comments including myself waiting for this for years.

You mean the collab suggestion with hundreds of thousands of likes?

Why is the top comment on every collab video some variation of this?

When 3 GOAT meets

I mean he did mention he's an introvert in his presentation

ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-ZxBF7WC0TQk.html here's the vid of his presentation

You should watch his video with Linus tech tips

I disagree, I don't think he is awkward at all

It's Mehdi

too bad most got wasted during his flight...

eh not a legend. Still good though

facts

@@michakrzyzanowski8554 who are you to say someones not a legend, this guy may look up to Mehdi and considers him a legend, thatll take this guy far in life. thnk before you say something. opinions are okay but not meant for everyone to agree

That's a true EE guy

The most obvious collab I never would have thought of. Maybe 10-20 years down the line, these guys should do another one, with improved equipment, because the last one was pretty much anti climatic.

I also hope one day to see him collab with Nilered and Cody's Lab.

Jeez, keep your fan fiction to yourself 🤣

ok

It's cool to compare the actual raw detailed physics to what is often just theory on paper or data abstracted through measurement

It also shows how terrifyingly powerful lightning is, the extremely high temperature (as in, much hotter than the surface of the sun) only lasts for an insignificant amount of time but can still cause third degree burns and fuse sand into glass. Lighting can literally flash-fry you.

I think that sodium contamination also plays a role here

@@Antek1234l Is there any sodium in the air? Where would the sodium come from? I mean, it's certainly reactive enough, but ...

@@3nertia Well, my theory is that they had sodium - contaminated hands. It may come from a table salt, or maybe even water, because tap water contains small traces of this metal.

@@Antek1234l What about sweat?

Mehdi is a *_treasure._* When's your turn gonna be?

ok

ok

My nebourghood toy store have better "Toys" are they Genius too??

ok

as a electro guy my self, i know how freaking dangerious it is, but it is a risk we take so that other DONT try it them self without the knowledge.

To be fair a lot of what he does on his channel is just "acting dumb for comedic value" plus copious amounts of capacitors, i doubt he ever puts himself in actual danger :)

That's just how Engineers are

Yeah he has masters in electrical engineering

@@suicidalbanananana I dunno, sitting on a heating element seems unwise. But he knows what we all come for. It's the copious amounts of knowledge that keep us all coming back time and again.

Well. It would require some really funky lenses to capture that distance lol. But they do have a planet slo-mo video showing a stupidly fast laser-based camera that can actually show you like moving across stuff.

@@5peciesunkn0wn At a distance far enough to keep 170m objects in frame, optics will be less of a problem. Making a voltage large enough to draw a 400m arc will require equipment from a different lab. Not even sure the ABB lab in Sweden can do that, and that entire lab is built for testing giant arcs.

The funny thing is, that if the technology gets even better and the footage surpasses lightspeed it will rewind itself and start playing instead of recording. I think. Yeah, nah, yeah, sure thing actually. We are so close to timetravelling right now.

Yeah, you could do some cool stuff with a laser and some mirrors, for sure.

Jesus Christ is the propitiation for the whole world's sins. They that believeth and are baptized (with the Holy Spirit) shall be saved; but they that believeth not shall be damned. Those led by the Holy Spirit do not abide in wickedness. *God is ONE manifesting himself as THREE;* the Father, the Son, and the Holy Spirit! Bless him! *For these three are one.* As I am led by the Holy Spirit, nothing I state is a lie, but the truth of God. Anyone who tells you differently is misinformed or a liar. They do not know God, nor led by him. Anyone who *claims* to be a Christian and is against what I am doing, and where I am doing it; the Holy Spirit does not dwell within them, they lack understanding. They know not God, read his word, and their religion is in vain. Do not hear them, they will mislead you, the lost cannot guide the lost.

*Mehdi

@@moeinsp2027 my bad, thanks!

Isn't the time 15:03??

This would be an awesome experiment. Maybe see how long you can make it

if you filled the maze with water it can

You totally can. It's kind of what a Lichtenberg pattern is.

Heck of a lot faster than slime mold.

solving it is literally the only option for it to short out between both ends. there's no way not to solve it unless it doesn't get inside the maze in the first place(which would be a fluke and not a valid test)

@Edline Nannencia I've not been waiting for any video sorry.

Thanks, I was looking for the timestamp to not watch the entire video.

Omg really that's so cool my guy!

@@rafakordaczek3275 You're weird.

Mehdi or Mahdi not medhi

Yes that would be amazing!

Sup posy. Just wanna say I am a big fan of your lcd display video. I also liked you hdr video :)

Love you Posy

I keep going back to the sabering video

@@Theslowmoguys0147 What a lovely bot

Electroboom has a response video to that. Perhaps worth watching

Electroboom already did the timing with oscilloscope. Doing this with Phantom can be very challenge because in nano seconds you have to have some circuit to trigger the switch while sending the time to Phomtom and we are talking speed of light here which can go weird easily when we mess about timing.

The influencer Veritasium is mostly full of it.

I would like to note that they would all turn on at the same if you count 'dimly lit' as being on. They'll only go fully on when the electricity gets to the lamp through the wire. I can't say anything about the ability of the Phantom to capture this though, but I'm concerned that the difference in brightness may be too much for the Phantom to show what is happening. This may make it seem like nothing is happening in the lamps until they all fully turn on one at a time. If they're able to film with different exposure settings then they could film both stages individually which would show how much or how little difference there actually is in the amount of power the lamps receive :D

@@tbird81 Full of it? Not really. But he can misrepresent things for the sake of getting a reaction. What he said about Electricity, for instance, was correct. He just made it sound like it was something nobody really knows. When any electrical engineer was well aware of everything he said.

To be fair, they did collab with ElectroBOOM so that one was actually expected.

I think you would need multiple frames per nanosecond to slow it down. If the whole thing is about 30cm (1 foot), which I think it is, and it is moving at the speed of light, which I think it will, then it will get from one end to the other in 1 nanosecond. So that means billions of frames per second are needed. The Caltec camera they used in their "Filming the Speed of Light at 10 Trillion FPS" video, published 27th March 2019, would do it.

There was a video I stumbled across a couple years ago about what I believe is called Macrotempo, the concept of making a kick beat of upwards of 1 million BPM, and it had an extremely similar result to Tesla Coil music, where no matter the sound, the frequency increases did in fact make recognizable notes . I believe the spark/boom of the electrical discharge is doing the exact same thing. Basically, I'm pretty sure you're correct, or very near to it if not
