Getting into the 4th of July, let’s check out some sparks that fly from ultracapacitors! YouTube user Afrotechmods shows us:

I got hold of some 2600F capacitors that can dump hundreds of amps. Normally these are used in electric cars to handle sudden stops and starts. Instead, I use them to vaporize bits of metal, and show you the 3 most important capacitor equations along the way.

Don’t do any of this, by the way! Have a great 4th.
