Hydrogen Cyanide Bottle
A small, unassuming bottle containing hydrogen cyanide (HCN, prussic acid), discovered by Sarah in Solon's basement lab. The Doctor recognizes it immediately by its chemical notation and deadly potency. Its clear liquid serves as the volatile agent that will be transformed into cyanogen gas through controlled reaction. The Doctor handles it with careful precision, warning Sarah of its lethal nature as they prepare to deploy it through the ventilation shaft above the basement.
