Homebrew PCBs

H2O2 is available at beauty supply stores in concentrations up to 
40%. (It's hair bleach.) It's sold in 1 quart bottles for US$5 or 
so. I get mine at Sally Beauty Supply. Some beauty supply shops only 
sell to licensed hair stylists but some, like Sally, do sell to the 
general public. 

Buying in small quantities shouldn't raise any red flags. I don't 
think I'd want to try buying a 55 gallon drum of it, though. :=)


Regards, Bob
