The Trigger Mechanism
The structure of the trichome is fragile. When an unsuspicious passerby brushes against the nettle, the rounded tip of the fuzz break off.

This point easy pierces the outer bed of the skin, act as a conduit for the liquid cocktail housed within the bulbous foot of the trichome.
