What to do with 0.4 farads of electrolytics?

[Amphiprion]

While going through the forgotten equipment boxes while cleaning out the electronics bay at work I found an old (1986) linear regulated supply, 24V and 10.4V outputs IIRC. Anyway, this thing was gigantic, old, and was gonna be chunked, so my buddy and I scavenged it for parts and I got a pair of 196,000uF 15V Mallory CGS electrolytics, and another pair of 36,000uF 35V of the same. Now these are 20 year old caps, so no way I'm putting them in anything I spend serious time on. But is there anything cool I can do with these? Rail gun? Pyrotechnics? Arc welding screw drivers?

So yeah, lookin for a cool project to use these guys with. Doesn't matter if they blow up. Anybody got any ideas, lemme hear em

I think that a decent use for them would be welding tabs to build NiMH and LiIon battery packs.

Whatever you do, be careful! Plan for what happens when they pop or melt, and follow all proper precautions for working with high current circuits. If you needed me to tell you that, then you might want to think twice of using them

Seriously though, you ever try to solder to the end of an 18650?

I usually just use a silver content solder with copper bridges to make NiMH packs... 850 degree setting on the iron.
