Hi Cari,
   
  The "blue man" is a US Representative that made his home brew EIS (aka CS) 
using Montana well water. Most farm wells are contaminated with fram 
fertilizer, which has a high level of nitrates. So what he was making was 
silver nitrate, which will turn one blue.
   
  That is why it is recommended to use the best grade of distilled water 
available.
   
  Too many thousands of home brews are around that can testify that there is no 
problem. Just make it with the proper materials.
