Bernoulli principle. When the plunger is pushed in, the air in the cylinder flows out at a high velocity through a small nozzle. The flow of air at high veocity creates a region of low pressure just above the metal tube. The higher the atmospheric pressure( from the air hole) acts on the surface of the liquid insecticide, causing it to rise up through the metal tube. The insecticide leaves the top of the metal tube as a fine spray through the nozzle. Ermm rasanya mcm ni jwpnnya
