Why does insecticide spray out when you push the piston? It’s Bernoulli’s principle in action. This comic shows the exam‑ready chain:
Air moves rapidly at the nozzle.
Fast air → low pressure at the nozzle tip.
Pressure inside the bottle is higher → liquid rises up the tube → fine spray produced.
The exam trap: don’t just write “liquid comes out.” You must explain the pressure difference step by step. Remember: fast air = low pressure, higher pressure pushes liquid up.
AHA! Spray comes from pressure push. Not by sight, but by INSIGHT!
