- PLEASE READ BEFORE POSTING:
Making Captured Lightning is LOUD - you may want to reduce turn the audio volume down. Skip to 0:51 to see discharge. This is a 15" x 20" x 2" 3D Captured Lightning sculpture being created inside a large slab of clear acrylic plastic (polymethylmethacrylate, PMMA, Plexiglas, or Perspex). These are also known as Lichtenberg figures or "beam trees". This specimen was passed through a 5 million electron volt (MeV) beam of electrons from a particle accelerator, flipped 180 degrees, and then passed through the beam once again. The high-energy electron beam injected trillions of extra electrons into the slab, creating two separate cloud-like layers of electrical charge, each located about 1/2" below the surface. We then released the trapped charge by poking the slab with a sharp metal point. This created a small defect that allowed most of the excess charges to rush out with a brilliant lightning-like flash and BANG. However, the main discharge doesn't remove all of the trapped charge, so thousands of small pockets of residual charge flash for up to 30 minutes afterwards. Before being discharged, the electrical potential of the internal charge layers exceeded 2.5 million volts. The powerful electrical discharges create thousands of small tubes and fractures in the acrylic, creating a permanent inch-thick "fossil" of their passage through the slab - a 3D Lichtenberg figure.

SOMEONE GET THE SLOW MO GUYS
I dunno if there's a camera fast enough.
greenaum, I don't know if you know, but there is a camera that can video light moving. So this should be a piece of cake for most!
I'd like to see them try, they've got to around 350,000 fps.
Yea!! I watched the creator's Ted Talk.
shut up
That is definitely one of the cooler things I have seen thanks for sharing.
I'm pretty sure this video contains many color things, not just one.
Liar Opps, supposed to be Cooler XD
xd
*coolest
?
I had no idea this would have secondary discharges for SO long. That blew my mind!
You should have done this in a dark environment. It would have been amazing to see what the sparks looked like.
Homie Bro lol fuck off
Safety first
Of course they're in it for the spectacle. Why else do you think they post it to youtube...
Momie Bro: Ouch, i accidentaly cut myself. You should not let that edge just lay around like this. :D
Jacob Moreno Agree!
some say it is still sparking to this day
the birth of Sauron
YOU GUYS ARE MONSTERS. WE DONT HAVE RIGHTS AS HUMANS TO CAPTURE A LIGHTNING AND PUT IT IN A CAGE LIKE THAT. IM CALLING GREENPEACE
Thanks doggo very cool
I wondered about the ongoing sparks/discharges in it, but then I read the information. Fascinating stuff! :)
I don't think the environment was noisy enough, we could still hear you say a few words.
Hehe - sorry about that. It IS a noisy environment. Its a 150 kW industrial electron beam with chain-driven carts, huge vacuum roughing pumps, water and forced-air cooling pumps, and high-volume ozone neutralization and evacuation blowers. I suppose we could have muted the audio and replaced it with elevator music... but it wouldn't have been nearly as close to "being there"... :)
blueknight get backfired
Now wait a minute.... all that gear was needed to generate the power to do that sculpture?
Yes. The high-volume vacuum equipment is essential for the 3-story high "vacuum tube" that's the heart of the particle accelerator. Chain-driven carts are necessary to move material into and out of the heavily-shielded accelerator room (which is behind 8 feet of concrete shielding to protect us). The electron beam generates large quantities of toxic airborne ozone and nitrogen oxides that must be safely evacuated from the accelerator room and neutralized. And the 200 kW RF power oscillator that powers the 5 million volt DC power supply requires a huge 3-phase power transformer and lots of water cooling. Keeping all this working is one reason that "beam time" is expensive...
and noisy. Just about everything there buzzes, hums, clanks, rumbles, or whooshes when the machine is in operation. Being LOUD is just the nature of the beast.
That's amazing!! How long does the lightning last?? I saw it just kept going and going! :o
when your working in the middle of a currently operating steel mill but you gotta record something.
:)
When can we get the Slow Mo guys to do a video with one of these?
OblivionFall Can't
Its impossible because its too fast. The slow mo guys wont catch anything. Its literally travelling at the speed of light
lightning travels at roughly 3700 miles per second, because lightning is not light
OblivionFail We've measured the speed of the propagating sparks electronically and optically. The tips propagate through the acrylic at up to 3.3 million feet/second, or about 631 miles/second. To capture them actually moving requires a camera that's at least 10-20X faster than the Slow Mo guys - about 3 - 5 million frames/second. The Slow Mo guys' camera would see one frame with nothing in the slab, and the next frame would show a fully-completed tree. Maybe in a few years when faster cameras become available. It IS on our bucket list. :)
Last Drop: That's true. Unfortunately the MIT camera you're probably referring to cannot capture rapidly sequential images of a unique event such as a propagating spark discharge. See the pinned discussion under "SOMEONE GET THE SLOW MO GUYS" where the MIT device is discussed. The tricks it uses will not work for this application.
While the flash propagates that fast, the whole flashing and creation of the channels would be orders of magnitude slower. Even with normal cameras you cans see the buildup and pulsing of lightning strikes.
so it think it would still be very interesting.
Amazing how nearly all cameras have a zoom and this guy does not use it.
Speechless
I love your work, Bert! Thank you for sharing the creation process, those who can't be there in person appreciate it :)
how long does that spark jumps in there for?
Well,it's energy,so i don't think it would go anywhere(unless they broke the glass)
That is impossible. The sparks are heat and light, which will eat away the energy stored in the glass. I just wonder how long it takes.
The main flash only takes about 500 billionths of a second. The smaller flashes occur very frequently after the main discharge, then less frequently over time. We have seen large specimens spark intermittently 20 - 30 minutes after the main discharge.
Thank you!
wow
0:52 the best part
WE NEED THIS IN 4K HIGHSPEED CAMS, YES IM SCREAMING FOR A REMAKE, PLEASE OH PLEASE
I'm pretty amazed by the fact it looks a lot like roots.
anyone mind telling me what black metal band's logo that is?
+
Canadian Metalhead hahaha fuck yeah
Canadian Metalhead ACDC ?
Van Der Graaf Generator - Still Life? czcams.com/video/WYBifGynf6g/video.html
I think it's slam metal
this has been the most interesting thing i've seen all year
I love how they say "particle accelerator", when in reality a cathode ray tube in old CRT TVs are technically a type of particle accelerator.
Is that Zues' workshop? It sounds like they are manufacturing the lightning bolts in the background.
Zeus ?
Hahaha genius comment
I wonder if you can "re-charge" the insulator to get the internal discharges back. A constant charge/dis-charge display would be a money maker for sure.
No such luck, unless you have a particle accelerator at home...
Thank so much to share with us, this extraordinary experiment.
Belive it or not but 0:52 this is it !- that feeling what I feel when I suddenly have an idea or get scared or motivation and so on - thats mean same happening in us(body , brain and so on). Very interesting finding .
I make these for fun. I work on a Linear Accelerator here at work and besides getting your hands on a 10MeV accelerator it is very easy to do. I use 3x3x.5 pieces of acrylic though. Anything this big is nuts.
Cool! We're limited to 5 MeV. But the upside is that we can make very large specimens.
found myself here late at night. What the hell is this? Looks cool.
Like an insulated cloud full of small discharges, "heat lightning. " capacitance inside dielectric
Absolutely astounding! This is art.
You should try using black 3.0 and doing it in a black room. You will not see the background at all. It should come out like lightning in space.
he created a universe within that metal plate, the tiny lightinings are super advanced aliens jumping through space time, exploring their weird universe, mining resources and trying to figure more about it.
At the end when the guy uses that flash light, the aliens start to build tiny massive cities close to the source of their universe, and they harvest this new resource. You can see them, they are those tiny bulbs of light that begin to appear. Some of them are far from the source, because they had to strategically place them further away due to efficiency in resource management.
I think this needs to go on one of those 'satisfying' videos...
nice lightning strike from PoE. Am looking forward to the build for 3.1v
holy crap....it does look like lightning but at the same time it kinda reminds me of neurons firing...like Nurves. did anyone else kinda think that.
Darkcon Drazenco yes I did
That is seriously Fn AMAZING
Thank you for showing us.
Absolutely Awsome.
Possibly the most incredible thing I've seen.
so far...
That was awesome - and apparently how the surface of mars was formed
And this is how our universe was born
this gets me to blink everytime, goddamnit.
Imagine getting that into your body.
Very cool. Maybe a scheduled recording while 'metal mayhem' stepped out for lunch.
wow creating a sculpture is just in a FLASH.
If I got this right, you turned acrylic into a capacitor because all that power discharged at once.
That's basically correct. However, because there are no metal plates on/in the slab, it really doesn't "look" like a capacitor. We injected layers of excess electrons (- charge) into the middle of the slab using a 5 million-volt particle accelerator. The outer surfaces of the slab developed a matching deficiency of electrons (+ charge). This is similar to the way metal plates in a charged capacitor develop a surplus of electrons on one plate and a matching deficiency of electrons on the other. Overall, the number of negative and positive charges are approximately in balance. Scientifically, the electrically-charged slab can be described as a "real-charge electret". An electret is the electrostatic counterpart of a magnet. We can also accurately describe the charged slab as a plate-less, high-voltage capacitor.
Prior to discharging, the voltage stress between the inner and outer charge layers was about 2.5 million volts. Since the charge layers are invisible, the heavily-charged slab looks no different than an uncharged slab. Similar to a capacitor, the slab stored electrostatic energy in the electric field between the inner and outer charge layers. This particular slab stored a relatively large amount of energy - about 4 kilojoules. When we manually triggered the discharge, we effectively short-circuited this "capacitor". The brilliant high-current discharge had a peak current of ~6.5 kiloamps, but it only lasted for about 500 billionths of a second. The peak pulsed power exceeded 2.5 gigawatts, which accounts for the considerable physical damage created inside the slab. The result is a beautiful "Captured Lightning" sculpture.
Interesting concept. Since this reminds me of the wood burning DIY devices I am adding this FYI: Additional safety information here: Make Lichtenberg wood art safely on the youtube channel of bigclivedotcom. At 2:09 he begins a detailed diagram including how regular power surge suppressors are not able to cut the power on microwave transformer jolts. He talks like an engineer and has very technical explanations as to why he says to never use a microwave transformer.
Thats a fractal pattern for sure!
Seriously, this would make some amazing slow mo guys content... Gavin? Dan?
Is it possible to put this on a stand with a power source to continually get those little sparks. It would make a killer night light.
Then, when it is done discharging, drill a small hole at the fracture point and install a strong LED light then frame it.
Unlike fiber optics, light doesn't follow the individual paths. The sculpture actually looks much better when an entire edge is illuminated by strips of LED's. For example, a similar specimen on display at the Museum of Science and Industry "Numbers in Nature" exhibit in Chicago, IL (USA):

that acrylic has felt the power of a darkside xD
I wonder if the same can be achieved by a cloudier perspex. Which could then have lighting behind it.
Edit: Never mind, found it on your channel. Awesome btw!
That's was.....electrifying
Truly amazing to watch
what if you hit it again, again and again? will the glass shatter if you continue to hit
Once you hit it, almost all the stored electrical charge is released. So, hitting it again has little or no effect.
If there could be a plug in version of this that would arc every 20-30 seconds when turned on and you could keep it in the 500-2000$, I think you would make alot of money. Is that even possible? I feel like adding in more would mess it up or something.
if the electricity would jump around like that for a long time and i could hang it on a wall... SOLD lol
what's that noise that sounds like the roof of your shop is about to fall down?
That's brilliant, you wanna get some bioluminescent goo in there, or glow in the dark liquid, or just normal liquid, put a black/white backing onto it and stick a LED on the entry hole
even after the guy removed the electrode, it was still sparking!
I never saw such a thing. Imagine seeing it in slow motion
Is it possible to have a steady flow of electricity keep the acrylic sparking so long as more power can be supplied?
Unfortunately, no. You might be able to illuminate it with flashing LED's to come close though...
If only you weren't recording on a spanish plaza at 7:30 in the morning, it would be much enjoyable
This proves we live in an electric universe and not in a Big Bang universe.
Trolls, GO!
I don't unerstand. Why do the sparks last after he removed the electrode? What's going on?
The grounded electrode is removing excess charge from the slab of acrylic. The main discharge removes most, but not all, of the excess charge. Small pockets of left-over charge cause the smaller sparks afterwards. See the links in the video description above for LOTS more information about what's going on in this video.
"You should turn down the background noise."
"What?"
"You should turn down the background noise."
"What?"
I frickin LOVE SCIENCE, it never ever fails to surprise me, but Im a stupid literature student
I wonder why it is that everything in the universe seems to branch out like that. I want to know why it's such a prevalent type of structure.
That is a profound observation. Similar patterns are seen in rivers, mammalian circulatory systems, plant branching and vein patterns, and various organs such as lungs and kidneys. Because these patterns are so pervasive, at least one researcher (Dr. Adrian Bejan) has proposed that it reflects a law of nature - the Constructal Law. These hierarchical branching patterns appear to permit the most efficient flow... of air, fluids, and in the case of our Captured Lightning Lichtenberg figures, even electrons! See also en.wikipedia.org/wiki/Constructal_law
Thank you! I'll be reading these now.
00:60 DON'T JUST STAND THERE!! GROUND THAT S.O.B.!!!! lol
I need to know the physics of this. Urgently.

Thank you. That video was awesome, so interesting! When I said physics (I'm a physicist) in fact I was talking about the raw fundamental physics (I mean...the equations for this phenomena, and how the solution for the path is fractal) but the video was a good start point from the phenomenological point of view, thank you! (sorry for my english!)
Jimena S, please check some of the technical references provided at the bottom of this page: www.capturedlightning.com/frames/lichtenbergs.html
You'll find a number of published references that describe the physics of various parts of the process in much greater detail.
Thank youuuuuu!! :D
This is how the producers of The Flash made Zooms suit, lol.
WOAH THAT WAS "SHOCKING"

That is so stinking cool!
Would love to see one videoed in the dark with in high speed and watch in slow mo. I know the main discharge is super fast, but so is a bullet.
Bunch of free energy is what I see. Has to be a away to harness those discharges. Maybe to a Battery. Or if you're British...a Batreee
@Bert Hickman Thanks again for sharing, this is really cool! Have you ever tried measuring or using the residual charge somehow? I suppose once you give the charge an outlet it would leave instantaneously and have incredibly low current, so I suppose you can't do much with it if you want to. Maybe pass it into another piece of acrylic? I wonder how much smaller the second specimen would have to be to produce a similar Lichtenburg effect, if there is even enough charge remaining to short through the acrylic?
Evin Elroy: Many years ago we measured the output discharge current for a number of small 4" x 4" x 3/4" specimens. The peak current was almost 600 amps but lasted less than 120 billionths of a second. It might be possible to use it as a very high voltage pulsed power source.
www.capturedlightning.com/frames/lichtenbergs.html#Measurements
Because most of the the smaller secondary discharges are between internal points, they cannot be easily harnessed or even measured.
awesome one time only sculpture
What an amazing, beautiful and peculiar phenomenon! This is one of the few existing positive aspects of man's manipulation of matter. But do give it time, for we shall expend the necessary resources to ensure its weaponization in the future - for our increased leisure.
i would put chris cornell's portrait in there with a blacklight
Wow, so beautiful. How much do things like this cost to make or purchase. Also, its acrylic yeah?
These museum-sized sculptures run $2750 including a custom lighted walnut base. One of these sculptures is on display at the Chicago Museum of Science and Industry's "Numbers in Nature" exhibit as an example of a fractal-like object. We have many other more affordable styles, some starting as low as $15, at capturedlightning.com
Bert Hickman oh wow, thats really incredible. I will have to look into acquiring a piece at some point.
Fractals everywhere...
close ground lightning bolts can go up to a billion volts..
Does it was 2,5volt on the glass or when you trought it the glass?
The interior was charged to 2.5 million volts> The discharge point wasconnected to ground, or 0 volts.
Used to use (smaller) acrylic blocks as "test targets" for commissioning and routine performance testing of Medical LINACS. I've still got a few up in the loft (test-pieces that is :0) ). Do you find any problems with solarisation? "Generic" PMMA seemed more prone to beam yellowing, whereas the "Good Stuff" (genuine ICI Perspex) seems far more resistant!
Phil S: We use high quality cast PMMA from domestic vendors in order to get consistent charge storage and discharging results. We have seen considerable variation in solarization between PMMA suppliers, and even between manufacturing lots from a given supplier. Most PMMA turns a lime green color immediately after irradiation, changing to an amber color after discharging. Recently we have seen some material turn a pink or rose color immediately after irradiation. Solarization completely fades within a couple of months in some material. Other material takes several years to fade. We even have a few pieces that have remained solarized for over 10 years. We suspect that differences in solarization behavior may be caused by differences in blends of various catalytic and UV-resistance agents that were added during manufacture.
Very amazing and cool!
Would it be save to transport or handle, before one discharges it? How long will it retain the charge if you don't discharge it?
At room temperature, most of the charge leaks off in 1-3 hours. If chilled with dry ice, charged up, and then maintained at dry ice temperature, the injected charge can be be retained for many months. Large charged specimens sometimes spontaneously discharge, so we have to be very careful when handling and storing them to minimize the risk of accidental electrical shock.
Making these sculptures took two beam passes. We use a custom carrying fixture (the wooden frame around the specimen) to manually hold partially-charged specimens so that we can charge up one side, safely rotate the half-charged specimens 180 degrees, and pass them through the beam again to charge the other side. A half-charged specimen this size holds over 2 kJ of electrostatic energy, so careful handling is essential.
That is the captured energy from a level 2 super saiyan. I'm just saiyan.
Soooo... how much does it cost?
Right at the good part my quailty drops fml
Se puede hacer en un cuarzo trasparente y en el vidrio se podria sellar con oro para ver la conduccion durante mas tiempo ???
hello, a question , how long does it keep the charge ?
It depends on the particular blend of acrylic and the temperature of the acrylic. At 20 C, the charge decays exponentially with a time constant of 30 - 60 minutes. If the acrylic is chilled to dry ice temperature (-78 C) the decay time constant is extended to 3 - 6 months, possibly longer.
-78 C*
thats why we have mountains in the world
What I wanna know is why there are still electricity darting around in it.
The lightning-like main discharge doesn't release all of the trapped charge in the slab. Small pockets of residual charge escape afterwards with small flashes, numerous at first, then slowing, and finally ceasing after 30 minutes or so. Almost magical...
How did you discharge the glass so you could touch it? It's amazing how much capacitance the glass has.
The clear material is actually acrylic (also known as Plexiglas, Lucite, Perspex, polymethylmethacrylate, or PMMA), not glass. Glass tends to shatter unpredictably. We inject trillions of electrons into the specimen by running it through a 5 million volt electron beam, flipping the partially-charged specimen over, and running it through the beam once again. This creates two intensely-charged negative charge layers, each located about 1/2" below the large surfaces of the specimen. A matching amount of positive charge accumulates on all the outer surfaces of the specimen. The inner and outer charge layers form a "plateless" capacitor. The inside charge layer becomes charged to about -2.5 million volts versus the outside surfaces of the specimen (which are at ground potential). When fully charged, this specimen only has about ~900 picofarads of capacitance. However, because it's charged to such as high voltage, it stores over 4,000 watt-seconds (4 kilojoules) of electrostatic energy. The electrical discharge makes a BIG bang and brilliant flash. All of the internal Lichtenberg figure fractures and channels are created in less than a millionth of a second! And, because most of the energy is dissipated in such a short time, the peak power during the main discharge exceeds several billion watts (gigawatts).
Someone cut the lights off I want to see this in the dark damn it
Honestly people, DON'T BLINK!
You know how cool that would've looked in slomo?
This is amazing! I'm going to look and see if you sell these anywhere. :)
should have done it with the lights off
Any idea where i could purchase a Lichtenberg figure?
Wow that's amazing and you have probably uncovered what the human brain looks like when we are thinking wicked stuff 👍
Spooners outings Yup
Get dem guys from time warp here.
That was AWESOME!!!
WOW nice fractals
