That could crawl out by itself?
If you are interested in High voltage work, you should realise that you don't need them to be solidCopper hemispheres will be fine made of thin sheetIf you go to garden centres or craft shops you may find hollow metal spheres on saleIf you get really stuck - get a solid sphere - or even a doorknob and use adhesive and thin copper foil to cover itThe big boys use copper wire mesh - for BIG things.
Or what u can do is buy a large salad bowl, steel, then goto home depot or lowes and buy a sheet of copper Or get copper flashing in the roofing departmentthen if its a sheet u can slowly shape the copper around the steel bowl with light hammering.wear safety glasses and thick gloves pper edges are very sharpIf no sheet copper avail, then shape flashing around the bowl with either propane torch, solder flux, and silver solder, OR a high power 100 to 200 W soldering iron with flux and 60/40 solder.
Yeah, there's that bowl with aluminum foil on top of it that: A) I don't know what's in it B) Don't remember putting it there and C) Don't know how long it's been thereWhat should I do with it?
