I wish I had this on video: made a coil and the rest of the wire, leading down to a little card/spool was hanging free, connected to the positive post, obviously. Forgot about it, fired the coil. Now I guess the lead wire was dagling or something because initially all was okay, until it touched the body. Dude! It flamed blue-ish and there was an actual bang, lol! Real nice. I'm still not using that battery, but I think it's fine...
Holy crap dude.. it would have prolly scared the hell out of me. Lol
