<< HCN is the active ingredient is Zyklon B (and is a poison). >>

Liza:
>what is Zyklon B?

Sorry for the typo. I meant: "HCN is the active ingredient in Zyklon B". Zyklon
B is a gas that was used by the Nazis (and also an insecticide, I think). The
other components of Zyklon B were just carrier substances; what actually killed
was HCN.
