Electrical Arcs at 1,750,000FPS – The Slow Mo Guys with ElectroBOOM
Gav and Dan team up with Mehdi from @ElectroBOOM to film electrical arcs by cranking this camera to the fastest speed it can possibly go. 1,750,000 frames per second.
Make sure you watch ElectroBOOM’s video too! – https://www.youtube.com/watch?v=-8qp4UjLANY

I don’t know if Dan will speak to me after going through so much pain!!😈
Would it move faster in a vacuum? What if you changed the gaseous medium it was arcing through?
@Harsh Adukia I haven’t watched his videos about the device so this is just my thoughts based on what I know. The thing is a chain of capacitors which build and store electrical charge in them and release it all at once. With his setup, full capacitors hold a lot of charge that want to release all at once across the metal nubs but they’re being held back by the capacitor. Think of it like a dam holding back water, a ton of water that wants to flow down but is held back by a giant wall. What I think is happening is that each capacitor in the chain is building up charge and when they max out the “overflow” moves to the next capacitor. When it gets to the last capacitor in the chain there isn’t anywhere else for this overflow to go. Now the dam from earlier is beginning to spill over as excess charge from the final capacitors searches for a new path – the gap between the metal nubs. As soon it completes its path across the gap it breaks the floodgates on all the capacitors since they now have somewhere for their charge to go and they all release it across each of the nubs.
I mean, your known for your setups shocking you, soooooo
I dunno.
He’s still friends with Gav.
Haha does Linus still talk with you? Didn’t he suffer more?
Working with Phantoms and searching for that one segment of spark is no joke. I was lucky to film with Phantoms a few videos back, and it gives me a huge appreciation for what Gav and Dan did for this video. What great footage you guys captured, resonant frequency and all.
I was really hoping to find you here.
@CD4017BE Well they did, you just have to remember to bring the cable 😅 (See Gavin’s comment above)
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
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.
dan is that guy who agrees to do everything no matter how dangerous it is
It’s all in the name of science. Unlike me, it’s for science and curiosity and ends in stupidity
He was an explosives guy, he accepted an unlikely death a long time ago
He is the best Guinea pig ever. 😂
@J W this is precisely how to be “that guy”. Not to be that guy or anything.
Not to be that guy, but if you think a properly working Tesla Coil is “dangerous”, you have no idea what you’re saying.
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.
@AYRON-X you really think a camera running at 1.75 million Hertz can capture light waves oscillating at hundreds of trillions of Hertz? They even said it in the video, you need at LEAST twice the frequency to see the resonant frequency. This camera is running at about 0.0000004% of that frequency.
Edit: missed a few zeroes
Amateur hour.
I would like to suggest that next time you start the repeating _____ before starting the camera
You can do it quickly with Python. You load the video frame by frame and calculate the sum of all pixels with the timestamp in a 2nd column. Sorting the resulting array for the first few value will give you the timestamp with interesting data
Video idea: get big cuts of meat or something that could replicate skin and bone and shoot it, I feel like that would be insane to watch in major detail and in super slow motion or maybe I’m just psychotic 🤷🏻♂️
I love Medhi. You can tell immediately how genuine he is and how much he absolutely loves what he does. So much fun to watch him with Gav and Dan
It really is a joy to see someone that both knows and loves what they’re doing.
Best guest appearance on the channel if you ask me. And they’ve had Will Smith and Tony Hawk.

ElectroBoom and The Slow Mo Guys is the collaboration we didn’t realize we needed 😀
Slowmo and photonicinduction would have been far more entertaining.
Why is the top comment on every collab video some variation of this?
You mean the collab suggestion with hundreds of thousands of likes?
I have been waiting so long for this :
https://youtu.be/mCfYi7634rU
You mean *you* didn’t realise? Because I have seen thousands of comments including myself waiting for this for years.
I love how Medhi turns socially awkward as soon as he’s around people… he truly is the mega nerd.
It’s the _labcoat_ guys who are awkward here… It’s like they can’t even look Mehdi in the eyes!
and remember, HE has a wife. I still have hope!!!
not really
I see you over here sitting on your throne of top comments!!!11
It is always fun seeing Mehdi on these collabs!
@Baphomet, you are a mega nerd too, speaking without regard for others feelings.
The arc pathfinding is really cool to watch. I wonder if you can set up a small insulated maze and see if it can solve it.
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)
Heck of a lot faster than slime mold.
You totally can. It’s kind of what a Lichtenberg pattern is.
if you filled the maze with water it can
This would be an awesome experiment. Maybe see how long you can make it
I’m only at 4:13 but it’s lowkey terrifying to see where the area around the strike on Dan’s finger is glowing yellow from the shock. It’s like a miniature version of how people can survive lightning strikes because the absurd temperature only lasts for such an insignificant amount of time
Low amperage?
@Antek1234 I stand corrected! 😀
@qwazse4 You as well, fair point!
@Antek1234 Fair point!
Correct, sodium is so luminous it doesn’t take much, and sweat and skin contains plenty to be visible this way. There’s also the instantaneous combustion of carbon and such.
The current flow is quite extreme (some amperes through that patch of skin), and it takes some depth to dissipate as it spreads out over your body — astonishingly this has little immediate health effect, unless the sparking is repetitive enough to cause internal heating (which can cause quite deep and painful RF burns!). It’s truly the case that squishy-meat-bags interact very little with electromagnetism, with thermal heating being the most common issue; you can say this is part of the proof that we are extraordinarily insensitive to it.
Okay being able to see the ACTUAL unedited resonant frequency of a tesla coil arcing is insane!!! That is crazy fast. But yes, I would love it if Mehdi comes back in a few years to revisit this idea with Gav and Dan when they have an even faster camera!
