Hazardous chemistry experiment describing attempts to isolate cyanogen iodide from impure cyanide salts by reacting with iodine in cold conditions, followed by extraction, drying, and crystallization. Observations include iodine vapor and potential cyanogen iodide formation, phase separation with organic and aqueous layers, precipitation and later redeposition, and the production of small, volatile, needle-like crystals that rapidly decompose into brown/black tar. The procedure yielded only a small amount of product, with significant impurities and safety concerns highlighted, and the video promises more content.
