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

[@theslowmoguys]

There is actually a very handy image search feature in the phantom software that would have helped us scan the images for significant changes in pixel values and found the arcs much quicker at 1,750,000. Just need to connect the phantom via ethernet to a laptop. Guess who forgot their usb to ethernet dongle for their USB-C only laptop? Heyoooooo.

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.

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.

[@tippership]

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

[@snackentity5709]

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

[@Deper91]

Electrical engineer here; My guess on why the marx generator lights up all at once would be that Mehdi IS technically correct, they are filling up from left to right. However, once the first stage is fully charged, my guess is that the impedance between the two discharge nodes is effectively infinite (acting as a perfect open), because there is another path of least resistance within the circuit, going to the next stage capacitor. Once that next stage capacitor fills up, rinse repeat down the line until you finally fill up the very end one. When that one fills to its max capacitance, there is nowhere left for the current to 'freely' move, so everything 'overflows' all at once.

[@wildavis3016]

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)

[@Deper91]

@@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.

[@wildavis3016]

@@Deper91 ok that makes sense thanks

[@MadScientist267]

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.

Do you guys remember the Veritasium riddle on how long it takes for a lightbulb to turn on, if the cables are extremly long, but the bulb sits next to the source? If your camera records at 1,5 million FPS light would travel only 200 m during two frames. So maybe if you use a km of cables and lamps that switch on incredibly fast it could be possible to actually visualize this effect. For example: 3 lamps (or any other device visually reacting on current), one at the middle of the cable and one at the start and end, but all are equally distanced from the source. All should switch on at the same time.

[@bertjesklotepino]

Electroboom has a response video to that. Perhaps worth watching

[@manabellum]

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.

[@tbird-z1r]

The influencer Veritasium is mostly full of it.

[@AnimilesYT]

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

Avid viewer of both channels. It’s awesome to see a collab between both. It’s also nice to see Mehdi when he isn’t doing his shtick. As hilarious as his videos are, it’s nice to see a normal person behind them. As an electrical engineer in training, it is super interesting to watch this and consider the principals behind it. I suspect that the spark gaps are probably firing sequentially rather than instantaneously, but the time difference is probably beyond what is measurable even with the TMX. Sort of like your speed of light video. Light is not instantaneous, but it moves so fast that it really takes something incredibly special to see it. I believe theory is that electricity doesn’t move quite at the speed of light, but it isn’t too much slower than that. As you said, to accurately measure it, you would likely need at least 10M fps, maybe more.

Mehdi is easily one of my favorite YT personalities. Stoked that y'all collaborated with him. Haven't even watched this yet and I know it'll end up as my favorite Slow Mo Guys video to date.

[@alildaisy2180]

These three have such positive energy I want them to be collaborating permanently!! I love all of them knowledges combining! Seeing electroboom collaborate while they do a sharp charge video would be SOOOO fun!

[@thehyperscientist1961]

The collab we never knew we needed. And I believe Dan's found a new friend to blow up stuff I see 😂

[@wirelesmike73]

I love how much fun this was for all of you. It's contagious. Great, and informative video. This was an awesome collab.

[@arbiter-]

that is crazy. electricity is SO fast that even 1.75 million frames per second can't make it look slow. incredibly humbling if anything, who knows if we'll ever be able to perceive the true magnificence of it

[@noahway13]

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

[@zvisger]

ELECTROBOOM AND THE SLOMOGUYS OMG the legends all in one video. This must have been why there was an earthquake today. They're too powerful to be this close together!

[@hsmoscout]

i'm not an electrical engineer but if that coil is creating music the way that an electronic instrument does i'd guess it flickers like that because all waves are made of smaller sine waves so we're basically seeing the small very fast rise and fall in charge caused by them which is also why the sounds produced by the coil are so rich in overtones

[@Incompetent_Hero]

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

Best collab I've ever seen in my life on you tube. Thanks for guys👏👏👏👏

[@ArmyHumor]

It wouldn’t be a Slow Mo Guys video if there wasn’t something dangerous happening.

[@MarioFanGamer659]

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

[@falcon1378]

I’ve been watching since I was 6, glad to see you guys are still rocking to this day!

[@matlabsolidworkstutorials431]

The Phantom 7510 has an input port that allows you to trigger the camera via the emi generated from the Marx generator. I’ve done that before and it allowed me to find the exact point where the spark event happened without sifting through the video at all.

[@Cpt.Croissant]

The fact that the 875k and 1.75million shots look exactly the same, really shows how fast it really is

[@Freeish]

The colab we didn’t know we needed but now cant live without

[@JoeyWoodside]

I’d like to argue that the reason you see the last arc flash before the rest is because of the speed in which the electricity bounces across those first several electrodes. The visual of the flashes occurred for the first few only after the last node zaps and the current was completed. It was the last to have received the electrical charge on the line therefore it producing the faint charge until it brightens like the rest of them. You gotta think… the other flashes were almost instantly bright, the last one took a second to light up like the rest. The fact that that charge was moving so fast through the first few nodes didn’t show the visual flash until the current was completed on the last lap. Thats (in my unprofessional opinion) a pretty reasonable assumption.

[@robfruchtman4662]

Hydraulic Press Channel just did a video about exploding ball bearings. INSANE. Replicating this at the speeds you shoot would be incredible.

You guys have excellent chemistry together and should do more of this collaboration! Great video

5:25 LMAOO this looked nuts

[@paulocarvalho7877]

@5:54 is essentially how the lightning stepped leader coming from the cloud meets an upward streamer coming from grounded objects. It also demosntrates how the ionized channels first propagate in the air by following corona discharges and when the circuit completes, the unconnected branches discharge. Nice job.

[@magicalpencil]

I've wanted you guys to film electric arcs for years now, I was hoping for Photonicinduction but Electroboom is a worthy alternative :)

[@谢天陈]

When the slow motion footage was playing, with the tranquil bgm, I had goosebumps. Sometimes when the world is slowed down, we can see more hidden details of the already known.

Mehdi is one of those people, you don't just watch for the entertainment, but you feel you wanna hangout with, have a beer together or something ^ He seems like such a genuine and lovely person

[@residuefingerz]

It's against his religion to drink.....he'd prolly rip an opium pipe with you lol or give you a handful of khat leaves😂

[@OverAndOverAndOver]

This has truly been the most informative thing I've ever watched, thank you

[@Fsant]

One thing I've been wanting to see for a long time is a macro shot of an HID bulb arc. It uses a roughly 20kv initial arc then levels out to 12v. And I think the way it kinda flickers for a split second would look pretty cool in slow mo

[@hendrix24]

Absolutely love ElectroBOOM. I'm with Dan. I never made that connection about hot air rising either. Until now.

[@McLarenKeith]

Mehdi could be such a good addition to the crew! He's great!
