The Impact of Dimples: MythBusters’ Iconic 2009 Golf Ball Car Experiment
In the realm of scientific experiments on television, MythBusters has carved its niche by debunking myths using scientific methods. Among the multitude of episodes aired over its 14-year span, one stands out for co-host Adam Savage: the 2009 Golf Ball Car experiment.
The Experiment: Applying Golf Ball Aerodynamics to a Car
In this fascinating episode, the MythBusters team explored whether the principles that allow a golf ball to travel further due to its dimples could be applied to a car to improve fuel efficiency. They selected a 4th generation Ford Taurus as their test vehicle and meticulously covered it with a few hundred pounds of clay, sculpted to form dimples similar to those on a golf ball.
Why Golf Ball Dimples?
The rationale behind this myth stems from the physics of golf balls. As a golf ball soars through the air, its dimples generate turbulence around its surface, effectively creating a slipstream that enhances its flight distance. The MythBusters’ hypothesis was to see if a similar aerodynamic advantage could be applied to a car, improving its fuel efficiency by reducing drag.
Scientific Collaboration and Rigorous Testing
Teaming up with automotive experts from the Academy of Art University’s automotive department, the MythBusters approached the experiment with rigorous scientific methodology. Using NASA technology, they crafted prototypes and conducted a series of precise tests to determine the car’s fuel efficiency with and without the dimples.
Results: A Significant Improvement
The team’s comprehensive tests revealed remarkable results. The dimple-covered Taurus exhibited a fuel economy improvement of about 14% over the unmodified version. To put this into perspective:
- A vehicle averaging 25 miles per gallon could potentially reach 28.5 miles per gallon with the dimple modification.
- A car achieving 30 miles per gallon could see an improvement to 34.2 miles per gallon.
Such enhancements in fuel efficiency could have profound implications for fuel consumption and emissions reduction.
Industry Attention and Controversy
The striking results caught the attention of major automakers, sparking interest and further experimentation. Despite this, some automakers reported differing results when they tried to replicate the experiment using their clay models. Regardless of these discrepancies, the experiment was a pivotal moment in the show’s history.
Adam Savage particularly cherishes this myth-busting achievement for its blend of scientific inquiry and practical application. The experiment not only entertained but also added a layer of scientific validation that influenced both professional scientists and the automotive industry.
Legacy of the Golf Ball Car
The Golf Ball Car experiment exemplifies the core values of MythBusters – curiosity, scientific inquiry, and the joy of discovery. It stands as a testament to how a simple, inquisitive idea can lead to significant real-world applications and influence scientific thought and automotive design.
