Re: plastic homebrew caps

Original poster: "by way of Terry Fritz <twftesla-at-uswest-dot-net>" <A123X-at-aol-dot-com>

I did an experiment with a HDPE bottle, it was a chocolate milk bottle, a 
very good shape. It ran for three minutes at 7500v, but failed almost 
instantly at 12000v. The puncture was right on a small gray speck in the 
plastic I saw while putting the foil on. Some shampoo bottles seem to be a 
good shape.
