Abstract
Abstract A fluid dispensing device features a hand held tool having at least three fluid supporting prongs. The prongs are arranged in pyramidal fashion to form a fluid containing cradle at the apex. An exact amount of fluid is held in the cradle by surface tension forces. When the prongs are flexed, the surface tension forces are disrupted causing a discharge of the fluid to an exact area of a body surface.
