Blowing up BIG capacitors!

- In this video, I have a few capacitors of different sizes explode by applying reverse voltage. The larger ones have a safety vent, which I block to make them blow up instead of just releasing the magic smoke in a small stream...
The voltage rating of the caps ranges between 10 - 450V and capacitance of 4,7 - 5700µF. Mostly electrolytic capacitors, but also a tantalum capacitor. - Věda a technologie
A quick experiment on capacitors I've been wanting to try for a while. Might as well share it here!
It was a challenge to get enough current through the larger caps to make them explode without tripping my breaker. I ended up winding my own transformer combined with a high current full bridge rectifier.
If you want to destroy things on mains voltage use a kettle or heater in a series circuit as a ballast depending on how much maximum power you want. That way you can destroy stuff and even under short circuit conditions you won't blow your breaker. You still need a pretty large bridge rectifier if you want more than a couple of amps. I have a heater with 1kW and 2kW settings, usually 1kW is sufficient to destroy most things and those caps pop nicely on mains voltage without the need for a rectifier. I have a chunky 10A bridge bolted to a computer CPU fan heatsink for blowing stuff up when DC is needed
I tried using a 2.2kW heater in series with a rectifier connected in reverse on the largest cap. Waited for ~10mins and the cap just got hot... However, the cap broke down enough to let me step down the voltage and feed way more amps into it.
Without the mains voltage treatment they didn't conduct any current at all with 40V reverse DC
@@Cskirt Yay! Now I hear your voice!
Because I haven’t even heard your voice
And now I have. Thanks for sharing your voice.
And I love “The Magic Smoke” coming out of toys which had many seizures. Heck, I even loved how the smoke came out of the capacitors!
Epoxy making the big resistors explode super fast… good one!
more please!
yes a FULL BRIDGE RECTIFIER
It was fun to see the big ones actually explode instead of just vent.
I miss when people like photonicinduction did stuff like this. Well done!
That guy from photonicinduction is really crazy,the channel is excellent!
Have you seen styropyro link 100 car batteries in parallel? Something like 85,000 amps - was trying to replicate a lightning bolt, lol.
I'm glad that the bigger capacitors were done outside in a big open area.
Is it okey to breathe the smoke?
@@akif7699 No, it's not safe to breath in any kind smoke that comes from a fuming battery.
@@Arlock41 Thanks! It is good to know.
@@Arlock41 uhhhhh... what happens if you do...
@@KoolFace. You will cause harm to your body. Lung damage is a possibility, if any of the liquid comes into contact with your skin it causes an acid burn.
Can't stress this enough that you need to get away from a ruptured battery as quick as possible.
This took me back to an incident I had with audio amplifier capacitors hat explodes right in front of my face, scattering some fluid. The explosion was so powerful that it knocked me unconscious. Afterwards, I was hospitalized for 2 weeks for burn injury and poisoning from the fluid
And the smell...
At least you did it right.
Full recovery?
@@fifiwoof1969 Yes, I recovered
Back in the late 80s when my friend and I were in HS we worked in an electronics store (like actually parts, not like Radio shack) and we'd get large "computer" caps all the time. We would annoy the teacher by blowing up little caps in the back of the electronics class , so we decided we needed to go bigger and were going to blow up one of the big caps we had. We buried it in the back yard, connected some twisted alarm wire to it and decided the best power supply would be to connect it directly to the outlet. Needless to say we had not got to the chapter in electronics class about how caps are shorts to AC. But the wire was so long (and a lot of it still on the spool) that it didn't pop the breaker but heated the whole plastic spool until it started to melt. No explosion. at least not that day... A few months ago I had a starting cap that was clearly not rated what it said on the box vent right at me when working on a homebrew 20HP phase converter. Fun.
I used to gut open old toys and electronics as a kid to look at the cool-looking circuits, now I'm 23 and watching people overvolt toys and exploding capacitors. Man, the Internet is neat.
0:10 dude literally fears nothing 💀
have you ever heard of electroboom
you don't see that thick glove?
@@LoganDark4357 yes I seen them, but I would never do that even with gloves on
@@iloveappleyoutube7198 good thinking
Dont try this at home

Thank you for your sacrifice- the smell always fills the room.

2:01 Did you see that bubble growing on the capacitor loll
It’s weird I feel bad that the large high voltage ones got cooked. They’re kinda expensive and not many are available. The 5700uF one is like 80 usd
Nice, loved how you got the larger capacitors to explode! They really had quite a lot of force with them, with one breaking the plastic enclosure, so I'm glad you took precautions by doing the tests of the larger ones outdoors!
I''ve noticed lower voltage caps often blow better than higher voltage ones. Might be worth a try. Some have 100,000 uF and are big cans. 16, 25, 35V all seem to be in a sweet spot, even the smaller 100-1000 uf caps. You need a high enough voltage for a good bit of energy, but low enough or it just goes "snick" rather than blowing up.
Bigger caps usually have a way to let out the magic smoke so it doesn’t blow up spectacularly
larger caps have an X or Y shape on their top, where the material is weakened. when the pressure increases, these parts will fail, and release the pressure instead of exploding
Mom : we have smoke maker at home
The smoke maker :
Я даже через дисплей почувствовал этот запах 😂
It's the smell that gets to me , it lingers for ages.
0:51 i died of laughter when instead of exploding or letting out the magic smoke it just became fat
2:48 That green flame is interesting! Maybe a boron compound inside the capacitor or something?
the small capacitors "we have lift off the tin can flew off and oil soaked paper and foil is spread all over inside the device"
I can't imagine the many smells ... Great video!
Don’t Try This At Home
But ouside
Try this at your home
But at school
@@Pokycraftgamer9 no
@@noahmoore3114 try this at your home :)
2:48 is that green fire falling!
Yep, because the burning of copper just like how fireworks are in different colors.
I love how big capacitors can act as either smoke or fragmentation grenade
you should try blowing up the hv capacitor from a microwave oven. those are big electrolytic caps, made in a big metallic can, and weirdly enough most of them don’t have a designed relief point if pressure builds up in it. ive seen them blow up like a legit grenade in some tesla coils made by clueless people who didn’t know that those caps handle high frequency in a pretty explosive way…
0:08 Welp, that was unexpected… 🤣
Excellent video, why is so good to see electronics and components blowing😂😂😂
2:46 green fire that's awesome
No way voice reveal!!!
I did a 440 volt 47,000 uF Elna one many years ago with an electrical engineer . It was loud .
green fire was awesome. great vid
that was some sweet plasma
0:50 its adorably cute !
Wow. There really is magic smoke in the capacitors. (2:51) 👍
I can smell this through the screen
Some capacitor are like smoke granades😂
All electronics work on a magic smoke: when the smoke comes out, the electronics fail💀🔫
Oh thank you, I was little afraid of those big ones. Now I don't :)
The tantalum would make a good cigarette lighter. Does AC work better than DC?
This looks fun
POV the inside of my amplifier when my cheap speaker wire melted the jacket and the wires touched 😬
What happens if you "replace" the caps in toys with those caps?
I connected up a very large capacitor the size of a garden bucket for the emergency lighting system. I accidently reversed the connections, a bit later we could smell something burning. I disconnected it. I hate to think that it would have done to the MDF.
Wow, that was violent! lol
That looks like fun!😂😂😂😂
Nice video! One thing I've always been curious about is high capacity low voltage caps (or even super capacitors in that case). I've got 2x 100,000uF caps @ 25V that act as battery substitutes for our dirt bikes and am very curious about failure conditions with over-voltage and a dead short discharge. At almost $40 a pop I'm gonna pass on experimenting on those myself haha. Guessing over-voltage will just do the normal "boring" vent. Dead short could be interesting though.
I've tried a 10F 2,5V supercap, but it was really bad... No pop and almost no smoke. I'd like to try a larger one with higher voltage rating tho, when I come across one with a decent price I'll upload it :)
Overvoltage will be more violent. UL has a "breakdown of components " test that involvesa 2S cap bank at high voltage (700vdc at 480vac rectified. " Caps charged, one half is shorted, other side is quickly overcharged to 700vdc while it is rated for 400wvdc. Weakest cap breaksdown and all caps on that side discharge through the one.
Fun times!
Should I in stall a some detector over my work bench? Or not
I like the green fire
Most of them seem to be safe (if not use a glue)🤗🤗🤗
I have a couple of General Atomics 10uF at 4000V capacitors. They are the size and shape of an automotive battery. They have no vents and if they were to go off... I would not want to be anywhere near them.
Thats a good smoke granade
Been thinking about this, if you take a cap bank of 2x voltage, charged through a resistor to limit max current from the mains, through a transformer and full wave rectifier. Have DUT cap of 1x voltage conected via magnetic contactor to dump energy into it quickly while the dc continues to pump up the voltage, the DUT will fail violently with all caps discharging through it.
Proceed with caution though, arcflash is no joke.
Could you theoretically make an electronic musket with this where you shove a capacitor down the barrel and instead of a firing pin have some sort of plate in the barrel that would make the capacitor explode and then get pushed out by the gas and everything else being pushed backwards
Unlike most storage devices, capacitors shrink as the voltage goes up…. At least until the dielectric fails.
Satisfying to see. Even though it’s a crime against electronic devices and components😂
The bigger ones (with epoxy) remind me of smoke grenades and Chinese fire/nitrate crackers
Got 2 of the big ones in my technics amp
I'm watching this thinking I can smell the burned caps. LOL
I want to try this at home
could the smaller ones explode more violently if suddenly connected to a fully charged huge 450V capacitor?
2:02 how to make a smoke bomb
The capacitors slowly became smoke bomb😂😂😂
And the Academy Award for Best Visual Effects goes to ..... the 400V / 2400µF electrolytic capacitor. Congratulations!
Before this video, I was looking at caps like at small grenades, and always avoided using them in my circuits out of explosions fear. Not anymore. They are not that nuclear! :))
Bro them trees getting the best high of their lives😂😂😂😂

Now you know why they put vents on the bigger caps.
Kaboom?
Yes Rico, Kaboom
ElectroBOOM would be proud.
He's in the next room licking the terminals.
✨Firecrackers✨
How do they fit all that magic smoke in them?
2:47 Why is there green flames?
Copper
Copper and sulfur dioxide gas
When I was a teenager I made a canon powered by exploding capacitors that would fire their aluminum shells. And once I accidentally overcharged a 480,000uf capacitor in my bedroom and it vented in a huge mushroom cloud.
hope your parents put you up for adoption after that
The house had to be covered under a 30,0000 ton sarcophage and is still closely monitored by the IAEC.
Boys, we have a new Smoke Grenade.
Cap that have hole for explosion (idk what the name, i can't hear what he's said) act like smoke grenade. Interesting. Anyway, @electroboom would love this
It's a safety vent, to ventilate excess pressure and avoid explosions
Average college electrical engineering undergrad lab experience:
Just give those to me I need them 😭

I like this smoke grenade
2:50 That was not magic smoke, it was magic fire! green and yellow fire, seems very healthy and safe lol
I dont even know why im watching this, ive seen this happen too many times with my major lab classes.
Still pretty funny watching cap go poof i guess
I have a large number of 3000uF that I plan to make 6 groups of 3-4 in parallel 🎉then put the groups in series to get the voltage up. Then you charge each group to 300V. I want to make a geological test bed with dirt & clay mounted on a copper plate. Charge the caps and set up a small diameter trigger wire that will drop to the plate. The wire melts but leaves an ionized plasma channel to dump all the current. Then look at the test bed to see what the blast did to the dirt. Probably only he one shot as I don’t know what happens to the caps.
Carbon dioxide emissions increased by this Guy
Uh oh, you let out the magic smoke
Nice explosions from those caps. Maybe you could take all the non-exploded caps out of the things you overvolted and pop them in another video or just at the end of the overvolting video.
Everyone should be try at home I'll request you 😊
Oh goody - - something to do with my old capacitors... 😅😂❤
What reverse voltage was used for big caps ? Still about 30V or did you have to go higher ?
I used 30 volts with high current to make them blow up quickly. But I had to prep them with 300V reverse for a few seconds, 30 wasn't enough to get the current flow initially.
Why are all the caps blowing up at 31.4V, even those rated at 50V?
Most electrolytic caps are polarized, if you connect them in reverse they explode at a much lower voltage
I've been curious about making a bullet from a capacitor.
Charge the cap just before firing...2 farads at 5 volts sounds right.
(Don't make that face! Multi-farad, low voltage caps have been on the market for years)
It won't carry much energy, but on impact, that energy will be released in microseconds.
Not much use against soft targets, but it make a 'mini EMP' on striking metal.

Expensive Smoke Grenade 😂
Overvolting toys #8? We’ll wait for it
It will be released tommorow 👍
@@Cskirtthanks
How big is a single farad?
Overvolting toys #9? We'll wait
I wish I had caps that big and not to just blow em up lol
I didn’t use a rectifier-just connected to the 120v AC.
I never tried to connect them directly to my 220VAC, I just assumed they could handle that when they are rated 400V+ and would "heal" on the positive half-wave.
When rectified and connected in reverse through a Variac, my 10 amp fuse blew at ~40V.
@@Cskirt the electrolytic caps shown do not like AC as you would know. I have popped 600VDC ones on 120VAC. Just takes ‘‘em time to “cook” just keep in mind popping caps is fun-but DANGEROUS! Used to do that years ago.
