The Geek Group shows us how to build a Bucket Capacitor. The process uses 12 beer bottles, I can think of a better way of emptying those bottles rather than dumping them in the bush. Looks like the crimp on connectors worked well here for Chris but I have never had much luck when crimping ring terminals onto solid wire, I normally solder them in place.
“The parts you will need are:
1 – 5 gallon bucket
12 – 12oz beer bottles
4 – canisters of table salt
2 – 1/4-20 brass bolts(can be regular steel, but brass holds up better to the saltwater influence) and nuts
1 – quart cheap motor oil(you want oil with no additives)
about 1′ of aluminum foil
a couple feet of 12AWG copper wire“
