Sachin and Rohit Velankar’s experiment not only provided a scientific explanation for the phenomenon of glugging, but also sparked a deeper interest and collaboration between father and son. Sachin, an experienced professor of chemical and petroleum engineering, recognized the potential of Rohit’s initial inquiry and together, they embarked on a journey to investigate the science behind the glug. Their research led them to discover that the flexibility of a container does indeed influence the way its fluid drains. By conducting experiments in their family basement and utilizing tools from the makerspace at Fox Chapel Area High School, they were able to create custom acrylic bottles with rubber lids to further explore the relationship between flexibility and drainage speed.
Through their experiments, the Velankars observed that containers with greater flexibility, such as those made of plastic or rubber, were able to dispense fluid without the characteristic glugging sound. This observation led them to develop a sensor that could measure pressure oscillations with each glug, allowing them to analyze the effects of different levels of flexibility on drainage patterns. By adjusting the diameter of the hole at the bottom of the bottles, they were able to simulate varying degrees of flexibility and confirm that more flexible bottles drained faster, albeit with larger and less frequent glugs. This experimental approach provided quantitative data to support their hypothesis and shed light on the underlying mechanisms of fluid drainage in flexible containers.
The father-son duo’s findings on the science behind the glug were so significant that they decided to publish their research in a paper, marking their first collaborative academic endeavor. Sachin Velankar expressed his pride in Rohit’s dedication and scientific acumen throughout the project, emphasizing the importance of seeing it through to completion. Their joint publication not only added valuable knowledge to the field of fluid dynamics, but also highlighted the power of curiosity and collaboration in scientific inquiry. The experience not only strengthened their bond as a family, but also provided Rohit with invaluable hands-on experience in a real-world scientific investigation, which will undoubtedly benefit his future academic and professional pursuits.
In addition to the scientific implications of their research, the Velankars’ project exemplifies the value of interdisciplinary collaboration and mentorship in fostering young scientists’ curiosity and creativity. Rohit’s initial question about the influence of a container’s elasticity on fluid drainage not only led to a groundbreaking discovery, but also instilled in him a passion for scientific inquiry and experimentation. Sachin’s guidance and expertise as a seasoned researcher not only enhanced the quality of their research, but also served as a source of inspiration and motivation for Rohit. This collaborative effort not only contributed to the advancement of scientific knowledge, but also exemplified the importance of nurturing and supporting young scientists in their pursuit of knowledge and discovery.
Overall, the Velankars’ research on the science behind the glug serves as a testament to the power of curiosity, collaboration, and mentorship in scientific inquiry. Their innovative approach to investigating a seemingly simple phenomenon led to a groundbreaking discovery that deepened their understanding of fluid dynamics and flexible container behavior. By working together as a father-son team, they not only strengthened their family bond, but also paved the way for future generations of scientists to embrace curiosity, creativity, and collaboration in their pursuit of knowledge. This project not only marks a significant milestone in Rohit’s academic journey, but also underscores the importance of fostering young scientists’ passion for discovery and exploration in the scientific community.
