Make Pyrophoric White Phosphorus from Matchstriker. Easy to do but dangerous (I burned myself by getting some of this stuff on me). Heating the amorphous phosphorus that is readily available from match strikers in an inert gas such as argon in a small tube changes the allotrope from from stable amorphous polymeric form to the unstable crystalline white (P4) form. Unlike the polymeric amorphous form, the white or yellow allotrope is highly reactive. It smokes and chemoluminesces in air. If left long enough it spontaneously ignites. Exposure of the pure white P4 allotrope to light results in a yellow coloration developing- due to traces of the red allotrope forming. When the white allotrope is in metastable liquid form, it instantly spontaneously ignites in air.
