- Making cavitation bubbles using electricity from capacitor bank filmed 100 000 frames per second using Chronos Ring! Thanks for Kron technologies for operating the ring and David from Tesla500 channel for building the capacitor bank www.krontech.ca / tesla500
Here is link to our mobile game beta play.google.com/store/apps/de... game is free to play and we would really appreciate feedback about it. Please send all feedback to hpcfeedback@gmail.com The game is going to be ready with in couple weeks and then released to public after all possible bugs and issues have been fixed. The game is again made completely by our friend Johannes who made also the previous games. - บันเทิง
This was the last indoor Chronos Ring video that we filmed so next one is going to be from 50 meter outdoor ring! So bigger stuff coming. We have also again new mobile game coming :D There is some gameplay as an extra content of this video and link to beta on description. It's again made by our friend Johannes who made also the previous games. So if you are interested on that please test it out and send all possible feedback to email address in description so we can make it even better before the actual launch.
You guys have a mobile game? What is it I'll check it out
Thank you so much for being such an awesome TH-cam channel I love you guys!
A lot of people seem really confused by the setup and why it must rotate, at the beginning of each chronos ring vid you might want to briefly mention that you have a video explaining how it works.
And this needs to be done in the deep sea chamber.
Needs about ten times the power and thicker wires. Bigger is always better. ;)
Using "the biggest switch we could find" and Lauri's Safety Stick 5,000,000 were good indicators of the electrical power involved. :)
Stick seems to be out of metal so could have used a short one likewise.
Yes and no....I have a buddy who's so terrified of electricity he was physically shaking when he had to replace his power inverter in his semi truck......some people are afraid and some have a deep and abiding respect for electricity....the rest have yet to be introduced properly to fall into one category or the other lol
Love to see some of Andy's stuff on the Chronos Ring: th-cam.com/video/coW1RHUsf_I/w-d-xo.html
@@StygianBlood I don't want to take this thread into a literal religious war, but your statement about _"deep and abiding respect"_ just reminded me how similar electricity and God are. You have to attend to both God and electrical safety to fully appreciate (know the value of) each.
Count yourself fortunate when you receive only mild reminders that your attention is slipping.
That's why I keep a cross on my desk, and the screwdriver with the arc scars in my toolbox
Freeze it into a block of [transparent] ice- it'll show the cracks propagating through the block when you switch it on.
Yes! that would be a neat thing to see filmed with the ring.
Well, at that point it'd just be ice breaking from a small explosion going off inside it. Plenty of videos on cracks forming in materials on The Slow Mo Guys' channel, but not so much of bubble cavitation.
@@firesong7825 Ice is a solid, it wouldn't cavitate.
@@tomf3150 I think ice should turn back into liquid if you get high enough pressure thanks to the electrical power. I would say an experiment with crossed wires inside ice cube would be worth doing.
"Safety stick 5,000,000." Yep, he's on board.
They're like little universes being born.
Hi there another great video unfortunately the spinning distracted me from seeing what was going on
A single camera cannot record that fast, each camera is recording frames as fast as possible, and stepping around in a circle is the most viewable way to have them synchronised.
Paul, the substance you need is called Ritalin... 🙃
@@davydiver have any available?
@@joshuagibson2520 sorry, the squirls broke into my stash...
@@davydiver damn. That's a bummer. Cocaiñe is actually cheaper anywho. Lol
i love seeing you guys grow, and seeing the increasing production value. you guys are great.
These are super interesting videos! Excellent job again!
Good! More Chronos ring videos! Liked your livestream yesterday rowing on the lake. Had to watch it on replay because summer is here now and so much work to do outside!
We were really pleased on our rowing performance so we are going to have plenty more of rowing streams this summer :D The 15 km trip over the lake is going to happen!
@@Beyondthepress OK! It will be another epic live stream I am sure!
This is perfect, my son is learning this in his science class. Perfect video to show him, thank you!!!
cant watch it with all the spinning
Yes! I want this from single camera.
The fact that it's spinning gives it the super slow motion.
@@Qwarzz
Literally not possible, you need that many cameras with timed frames to achieve such slow motion at that resolution.
Totally agree, lose the ring thing and get a normal slow-mo camera.
imagiande that you control the angle of the camera by selecting a camera on the ring
Been watching you guys for a while now. You guys are so cool
This is truly amazing, to say the least. Truly magnificent, the Chronos Ring videos are something I'll be looking forward to in the future.
100, 000 fps is truly mindblowing
Love this excellent quality thanks guys watching from england :)
Excellent video guys and girls! These kind of experiments are fascinating indeed. Keep up the outstanding videos!
8:15 Capacitators. xD
I used to have a mate that called them that, so I made a joke of it calling them capacitatoes in response.
Honestly this is quite amazing! For real that last bubble and implosion was so cool...
The spinning I think is cool I enjoy the perspective
I really like this intro, well done 👍🏻
Awesome work guys! I do have a couple notes for improvement though:
1. I Hope you guys put some big diodes in place to protect the capacitors from damage.
The inductive kickback from the sudden release of energy needs an alternative path to go back through other than backwards through the capacitors.
2. Also you should create your own guillotine type switch that will be durable and easy to unweld. Switches are simple, all you have to do is slam two pieces of copper together quickly! A spring-loaded plunger, held back by a pin as one connection, and the surface it strikes is the other connection.
Looking forward to the next video!
That last one looked pretty good actually. You could definitely see the bubble get bigger again at the end.
I think for a better result you would have to use higher voltage caps, maybe 5kV or so, some more energy, and then use the water itself instead of copper wire to complete the circuit. That way there should be less copper getting vaporized.
And also ideally use a better trigger switch. Ideally a high voltage thyristor, but at least something with very large contacts.
Frankenstein knife-switch.
Would be interesting in a taller container too for more water pressure on the bubble.
@@firesong7825 That wouldnt do much as even a 1m high container will only add 100mbar more pressure on the bottom (10% more). For that you would have to seal off the container and then pressurize it.
Nice experiment!
I worked as an industrial mechanic in the water treatment industry . I've heard cavitation and seen the resulting pump impeller damage , interesting to see it take place .
What about exploding some capacitors/resistors or other electrical equipment in the chronos ring? Video idea maybe?
I agree, some nice fat electrolytic capacitors should be wild. Maybe Big Clive could help you out.
Yes that would be awesome! Could try different combinations of caps too, to see which one gives the best chooch factor of an explosion. Ceramic or tantelum caps might be interesting too. Or maybe even mosfets. Try to give 240v to the gate. She'll be alright!
Rodocal2007 did this (even with LED's!!) but without a high-speed camera!
Awesome Stuff
Kind of cool! Thanks!
Beautiful!
I really wish David would make some videos again. I loved watching his videos, very educational. The DLP chip and the e-charger are two favorites of mine, along with the flying tube thingamabobber.
Need an air spark gap switch for dumping the power from the capacitors both quicker and more efficiently.
Yes, or an SCR for medium voltages like upto 2000V, or some kind of thyratron if he was running 10s of KV. I done a few tests like this with pulsed DC from energy caps into water, produced some good effects, but I didn't have no fancy cameras, its a shame the electrical setup is not as grand as the camera setup. These water and HV pulse experiments are difficult to find on youtube.
Fantastic.
Best collaboration ever
That was really interesting!
Fascinating and very clever
I think thunderf00t would be interested in this experiment
Getting him to try it with his alkali metal solution would be interesting.
Wow this intro is damn professional
So cool :-)
Little fun fact of the day, using ultrasound to create such cavitation bubbles can make them reach ridiculous temperatures (around 5000K) and ridiculous pressures (around 1000 atm).
amazes me that a living creature (the pistol shrimp) can create such forces as well - th-cam.com/video/1wBYPjkGRdo/w-d-xo.html
these videos are awesome but if i watch this in VR, it makes me motion sick becuase of all the fast spinning. My head is spinning now, i have to finish watching on desktop later.
You can reduce the playback speed - that might help.
Ritalin...
Lauri's squat game is strong! Gopnik seal of approval!
Fascinating.
It looks like outer space
now you know what the birth of a universe looks like
Awesome experiment. I’m really surprised the glass containers didn’t shatter. 🤔
Was waoting for this also do collapsing bubble with sound
interesting 👍😀👍
It looks like a mini sun made in the labs amazing!
great video, i think the beauty of the chronos ring for something like this is being able to have the best possible viewing angles, not constantly changing the viewing angle like it's a scene from the matrix every time. does it only shoot like that or does it do high speed per camera?
Can you rotate slower? Then it will be much better to see. Awsome video’s ❤️. The temperature rise is enormous in cavitation
totally dizzafying, not clear
They would probably have to rotate the whole ring.
Need thinner wire (less vapor to cloud up things) but more voltage. Like 10-20kV and 5kJ and maybe 50,000-100,000 amps (enough to shrink a quarter) to heat it to maybe 100,000 degrees. Cheap 300v electrolytics have way too much ESR/ESL to be useful for heating/exploding wires fast enough unless you parallel a MJ worth, and are then very difficult to control (a few V is the difference from exploding wire and exploding the table or entire room).
I agree completely, more volts is needed, a more serious capacitor bank, and something like a thyratron. Must have blown all the money on the cameras, one would have been sufficient. even a 60KV 3uf cap can deliver 100KA ns pulses into a dead short - that would have been something cool to observe. my situations the opposite, I have lots of electrical stuff but no fancy cameras, one would be plenty for me.
I think that the intro to this video is like the best frickin intro in the history of the universe..👻
Very interesting
Really Cool to see the effect. I wonder if different metals of wire will create different explosion and ignition images.
Hey guys. Love your channel. I was wandering. How about you break a Prince Rupert's drop on oil. Since it's thicker than water. What would happend? Anyway, I love HPC an BPC. Both are great.
Today we have friends from the channel:"So you think you can out geek us?"
At 740 in the clip , am I seeing it rite? is that like small flashes of like lightning or electric flares from it ?it happens a couple of times and ever so briefly but I am sure that's what I was seeing there ,,, may someone tell me am I seeing things ???? Or was it reflections on the glass potentially??? as they spin around it so fast I well I'm not sure what it was if someone could help or tell me if they see it too please
Another great video 😼mr meowski approves 👌
Wonders when you use transducer in water an bubble if there is a way too trap something inside of it since it does heat too the point of the sun an repeats would be possible too heat said inside of it.
The ring gives two advantages - obviously 360 view, and max FPS per cam * number of cams (theoretically). How about rotate the subject to match the camera capture sequence to give a nice traditional shot with super high FSP? 360 is nice for some subjects, but is mostly sickening/dizzying.
This was filmed at 100k fps. There are 48 cameras in the ring. To rotate the object so it's facing the appropriate camera means that it would face 48 cameras in a single rotation. To reach 100k fps the object would have to rotate at around 2k rotations per second, or around 120k rpm. Not a simple feat.
You could probably turn the spinning video into a 3D render- then replay it from any angle without the rotation.
They did that with the CD shattering video.
those tesla500 they really need to play more with their rig on youtube
i wonder how much the depth and distance to the wall of the container matters.
could you please post the last segment (7:38 - 8:08) at lower FPS? it looked really good, and seemed like there may have been at least a couple cavitation pulses between just a few frames (8:02 - 8:04)
burned through my high-speed allotment of data to watch this, and HOLY SHIT! Too cool!!! Imagine with BIGGER capacitors!
Did you de-gas the water (e.g. with a vacuum pump) before this experiment? It's my understanding that the cavitation is more powerful if there's no air bubbles in the water.
That's definitely a bubble-shaped space within the water, but I don't think it qualifies as a cavitation bubble. Explosion bubble, perhaps. Cavitation happens when an object, like a ship's propeller, moves through the water at such high speed that the water separates from the surface of the object, leaving an empty space (well, probably filled with water vapor). The problem with cavitation on ship propellers is two-fold. 1. You lose propulsive force from the propeller since the water isn't flowing smoothly across the surfaces, and 2. the collapsing of the cavitation bubbles emit a sound. That sound isn't too much of a problem for normal ships, but it's a dead giveaway for military ships when enemy ships can detect the tell-tale sounds. Oh, and 3. cavitation causes excessive wear on the propeller.
But how bubble created the spark? is it because of the heat released during the spark steaming the water? or it is because the electrons on the spark traveled to the water bouncing the electrons of the water molecule?
The into alone is worth a "like" on this video!
You might look into switching the current on/off with a large 'brick' IGBT from Semikron or similar. This would separate the humans from the high voltage switching. You could trigger the IGBT with a 9V battery, or be a bit more sophisticated and do it with a pulse generator and control how long the power stays on. I have a background in pulsed power (which is what you are doing). It's considerably more dangerous than if you just got shocked with a wall plug due to the current available coming out of the cap bank (hundreds or thousands of amps). Please look at ways of doing this more safely.
Got another idea to get the wire to explode where you want. Solder the small wire to the supply wires then half cut the small wire with a set of side-cutters. The solder should eliminate the arcing and the half cut should make a hot spot.
On the last test, when the bubble collapsed, the bubbles that formed on the sides of the jar formed, disappeared for a minute moment then formed again. No mention of that, so I’ll assume the team was concentrating on the main bubble.
Did they say how many volts and/or amps they put through the wire
Awesome video. I love Your channel. I will try it but I will use a huge thyristor instead of the mechanical switch. The mechanical switch wastes huge amount of power for arcs between contacts. Thyristor is much faster and its voltage drop is only about 1.5 Volt. This will allow me to concentrate as much energy as possible into the 'exploding' spot.
Nice, it could do with a higher voltage capacitor bank too so you can have a longer arc and dissociate more of the water.
I kinda want to see what happens if you put some small coils in each wire before they meet so the arc occurs in a tangential magnetic field generated by the coils, it might shoot out due to the lorentz force the way a railgun does, probably won't go far but a directional shockwave in water might be cool.
@@samheasmanwhite Good idea. I will try this weekend. The only problem is that I have really cheap camera that makes only 25 fps so I can't really make slow motion video. I have already tried it but there was always like one frame of unfocused arc globe.
@@KUBA64official Ooh, yeah, arc photography is a bit tricky. But if you have a still camera that can be triggered and some way of making an adjustable delay you could trigger it with some delay from the triggering circuit for the thyristor and repeat for different delays. Wouldn't look great but it would at least show how the bubble evolves over time, even if it looks a bit different in each frame. That technique can get you arbitrarily fast framerates if what you are observing is repeatable enough and the shutter is fast enough.
@@samheasmanwhite Thanks a lot for your advice. I have already tried. I found out that I can set my camera to 50FPS mode which is a bit better but of course my video can not be compared to this one. The best result occured when I put 15V zener diode in reverse direction into the water instead of a piece of wire. I have 2200uF capacitor which I charge from mains voltage through 100W tungsten bulb and bridge rectifier. The bulb indicates the state of charging. I will upload video about it but I will speak Czech there.
@@KUBA64official Huh, the diode thing is interesting, good to hear you got somewhere with it :)
If you want to "create" cavitation bubbles without dangerous electrical equipment, get a smasher mantis shrimp
Great show, I'm not keen on the Chronos ring view tho, a fixed camera make me sense in my humble opinion 😆
Scale it way up!!! ⚡⚡⚡
Here is a link to Lauri’s YT video about the Chronos high-speed cameras: th-cam.com/video/zFOOY8MjChc/w-d-xo.html
Aah i see! So thats how they filmed the Matrix bullet dodge scene!
More or less...
The tech used to film that scene was what eventually lead to rigs like this.
Kiitos! Safety Stick 5 million in online store yet ? Complete line of safety gear for every situation: Safety T-shirt (with Nellie), Plastic sunglasses, Safety Stick, and tennis shoes.
Makes sense that the first setup had two distinct "explosions" as the connection points has significantly higher resistance than even the small wire inbetween. Basic Ohms law 😉 Ever had a voltage surge through an electrical system you'll notice it's the connections that get burnt, the poorer the connection the greater the burn.
Please set up another jar beside the one being harmonized to test for sympathetic resonance. If it works move the second harmonized further and further away to measure its range
Wicked
How about using salty water and get rid of the wire altogether? Would that work?
Cavitation is such an interesting scientific phenomenon. While it has been studied for many decades in many types of engineering, seeing it under the Chronos Ring is very revealing.
What if you did this in pressurized water or deep underwater would the collapse be more intense
Very cool! I've always wanted to see something like that at insanely fast framerate. But I believe the flaw in your system was 300 volts on the capacitors. You need at least several thousand voltas to effectively explode wires and maintain ionization. To put it simply, when the wire starts exploding from the sides, 300 volts is too low to break down the resulting vapor gaps and the process doesn't work so well.
I dont think breakdown is an issue here. I think the wires didnt even go apart completely. It's just not enough energy and not fast enough, and the copper that gets vaporized makes everything cloudy. With higher voltage, the energy would be dumped faster, and you could leave out the thin wire in the water because the water itself should conduct well enough, so almost no contamination.
@@Basement-Science Yeah, the faster energy input, i.e. higher peak power means a lot. Completely agree.
I don't know the name of the KronTech operator, but his "laptop" is awesome! what are the specs?
To much spinning in the video. It’s hard to see pictures. Other than that good job 👍.
That collapse is insane! How can it be so much faster than the expansion?
Hi, Can you give me details for power bank, to buy ?
Few more ideas how to see the cavitation. Melted copper in the water (dangerous it explodes), trick with hitting beer bottle from the top, and what you already done but with higher voltage it can break rocks apart, and underwater nuclear blast ;)
You can make cavitation bubbles at home without the fancy set up shown here. Just fill a glass beer bottle with water and slap the top of it HARD (wear gloves, it can sting a bit). The cavitation bubbles will blow out the bottom of the bottle and make a nice mess of water and broken glass!
Instead of the giant switch, wouldn't it be better to use like a high amperage HVAC contractor? I would think the pulse would get less resistance from the initial contact than a turn switch. Plus you can get rid of the safety switch and use a 24v signal instead
Everyone is complaining about the framerate, but realize that:
1. If you're doing actual science with it, it would be helpful in some cases to see it from multiple angles.
2. 100,000 fps is a lot. This setup gets around shutter speed limits by activating the camera in series around and around the ring. This produces a spinning effect but offers high resolution, high framerate video for a (relatively) small amount of money.
Stop asking for a redo with a more traditional high-speed camera. Unless you have money or connections, those are hard to come by. Be thankful they were given this opportunity instead of being angry it doesn't meet your quality standards.
hey guys i think you should try doing what you did in the Most Dangerous SOAP BUBBLES Ever!! video with these cameras i think the soap bubbles in the small house would look interesting, also i hope you guys have a gr8 day
Am I the only one wondering how much force it would take to crush the camera rig?
I love the idea of seeing things in every angle, but in these situations it would be alot better off if it was shot by a single camera at a much closer distance.
Still really cool though
A single camera cannot record that fast, each camera is recording frames as fast as possible, and stepping around in a circle is the most viewable way to have them synchronised.
Make a wire with a stretched neck in the middle, bend it so U with the neck at the bottom and lower it into the bottle.
so the only weak point in the water is the necked point at the bottom of the U.
I love y’all!
I need that T shirt
This guy knows about some unintended HDR 😀😀😀😁😯😉😈😈
A high power carbon switch may help with the switch welding it's self together.
I want to be interested in the cavitation but I'm distracted by the Van Halen leggings.
LOL
That's interesting footage, could be used in a movie showing underwater explosions of submarines or something. That's how George Lucas made the space explosions in Star Wars by filming pyrotechnics explosions from underneath
ohh a new game. I was playing the original one on my phone then got a new phone and could not figure out how to get my info to the new phone. I could install the game and start all over which i didn't really want to do :( So lookin forward to the new one to start fresh again.
Should have tried with tungsten wire or something else with a really high boiling point.
Molybdenum? Periodic Table of Videos got some interesting results melting this slowly in a vacuum chamber, including VERY bright light.
Would work better with a metal foil though.
