The spray bottles used as window or household cleaner or perfume spray works on: __________?
- A. Capillary action
- B. Bernoulli's Principle
- C. Pascal's Law
- D. Stoke's Law

In a spray bottle, rapidly moving air lowers pressure above the liquid, allowing atmospheric pressure to push the liquid up the tube and disperse it. This is an application of Bernoulli's principle.
