Absolutely most-definitely don’t even think about trying this at home, but…definitely most-absolutely be sure to watch the video below to know what’s possible. I frankly had no idea a capacitor was capable of so much smoke. The 220µF capacitance rating can be seen on the lid of the component, but I don’t see a voltage rating so it’s unclear what they’re potentially pumping through the component – what appears to be a Nichicon electrolytic capacitor, possibly one of their large can type aluminum caps, maybe the LGL, LGM, or similar capacitor. Either way I’m all ԅ(☉Д☉)╮
(that little flash of electricity near the end is a nice touch too!)

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.

…but it’s supposed to be blue!
I’ve seen large electrolytic capacitors fail from generated voltage in e-bike hub motors – they exploded inside the controller housing, filling it with shredded insulating material.
