Homebrew PCBs

From the article:
"using a mix of the liquid hydrogen peroxide, chapatti flour, acetone
and acid."

This doesn't make sense, as flour is not used in the manufacture of
acetone peroxide.  Sometimes acetone peroxide or benzoy peroxide is
added to flour in small amounts in order to bleach the flour, ergo the
bleached flour you buy at the store.
