>From what I understand, glass is the only way to go when making bottle
caps. When I first made them, I wrapped the outside in alluminum, but have
since found out that putting the caps in a SW bath is much more effective.
Currently, with 9 12oz glass bottle caps in parallel, I am getting around
12,000 pico fareds.
