- 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. - วิทยาศาสตร์และเทคโนโลยี
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!
I'm glad that the bigger capacitors were done outside in a big open area.
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!
2:01 Did you see that bubble growing on the capacitor loll
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"
0:51 i died of laughter when instead of exploding or letting out the magic smoke it just became fat

0:08 Welp, that was unexpected… 🤣
Thank you for your sacrifice- the smell always fills the room.
0:52 THIS IS THE BEST XDDD
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
2:02 how to make a smoke bomb
No way voice reveal!!!
0:50 its adorably cute !
Dont try this at home
"Try this at School"😂
2:47 Why is there green flames?
Copper
Copper and sulfur dioxide gas
ElectroBOOM would be proud.
2:48 is that green fire falling!
Yep, because the burning of copper just like how fireworks are in different colors.
What happens if you "replace" the caps in toys with those caps?
POV the inside of my amplifier when my cheap speaker wire melted the jacket and the wires touched 😬
The tantalum would make a good cigarette lighter. Does AC work better than DC?
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...
0:10 dude literally fears nothing 💀
I'm watching this thinking I can smell the burned caps. LOL
2:03 that noise lol
Wow, that was violent! lol
Bro turnes capacitors to smoke grenades
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! :))
"Don't breathe this!"
2:02 a nuclear bubble 2:03 uhh
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.
Spicy!
Smoke grenades 🙅♂️
Capacitors 👍
I wish I had caps that big and not to just blow em up lol
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
Green fire capacitor
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.
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.
imagine how bad it smells there
Requests for overvolting toys #9: Hip hop goose, Fisher Price Beatbelle, Furby Boom, a random dancing doll.
Overvolting toys #9? We'll wait
How dangerous is that smoke
It's actually quite stinky.
And probably not healthy to breathe either.
Overvolting toys #8? We’ll wait for it
It will be released tommorow 👍
@@Cskirtthanks
@Cskirt for the bigger ones I like the Poof! Airy Sheldon
big smoke

Noo bro !! How can you destroy that beauty gift it to me , or at least use it to do a big short circuit
I have a lot of them, if you live nearby you can have a few! I've abused them by shorting through various things, but still works fine :)
@@Cskirt oh thanks brother !! I think I am too far but still aprecciated the offering , I am from Argentina
@@rodriguezfranco3839 Oh, yeah with that shipping cost it'll probably be cheaper to buy them locally
