Refine the design as needed to achieve a smooth and functional dispensing mechanism.*Tips and Variations*- *Use a more advanced mechanism*: Incorporate a more complex mechanism, such as a spring-loaded system, to enable smoother dispensing.- *Add a locking mechanism*: Incorporate a locking mechanism to prevent unauthorized access to the cigarettes.- *Experiment with different materials*: Use different materials, such as plastic or wood, to create a more durable and functional dispenser.- *Create a themed environment*: Build a themed environment around the dispenser, such as a retro-style cigarette machine.*Science Project Considerations*- *Hypothesis*: How does the design of the dispensing mechanism affect the efficiency and reliability of the dispenser?- *Variables*: Independent (dispensing mechanism design), dependent (efficiency and reliability), controlled (cardboard material and construction method).- *Data collection*: Record observations, measurements, and calculations related to the dispensing mechanism's design and its effects on the dispenser's efficiency and reliability.- *Conclusion*: Analyze results, discuss the dispensing mechanism's design and its effects on the dispenser, and suggest improvements for future designs

The power of the technology is that it allows us to directly analyze the effect of a stimulus, in this case smoke exposure, on lung in what might be thought of as an in vitro human pre-clinical study, Ingber said
