📋 Summary

Introduction to the Scientific Game Show

In this engaging episode of the podcast Wow in the World, hosts Mindy Thomas and Guy Raz present an edition of their popular scientific game show, Two Whats and a Wow. The theme for this session is "Landmarks," where listeners are challenged to identify the single scientific truth among three statements regarding famous human structures. The show blends education with humor, encouraging listeners to engage with history and science through interactive rounds.

Round 1: The Great Wall of China and Sticky Rice

The first round explores the architectural history of the Great Wall of China. The contestants were presented with three claims: the use of sticky rice in construction, the height of the Taj Mahal compared to the Empire State Building, and an all-wombat orchestra at the Sydney Opera House. The "true scientific wow" revealed is that the Great Wall of China was constructed using "stone, bricks, wood, and sticky rice." The hosts explain that scientists discovered in 2010 that "sticky rice mortar"—a mixture of rice and lime—provided superior strength and water resistance compared to standard mortar used in historical construction projects spanning over 2,000 years.

Round 2: Thermal Expansion and the Eiffel Tower

In the second round, the focus shifts to the Eiffel Tower. The winning statement is that "the Eiffel Tower grows 15 centimeters in the summer." This phenomenon is attributed to "thermal expansion." Because the tower is primarily made of iron, the heat causes the metal to increase in volume during the summer months. Conversely, the structure shrinks back to its original size as the weather cools down, demonstrating the direct impact of temperature on large-scale metallic structures.

Round 3: The Statue of Liberty’s Transformation

The final round addresses the iconic Statue of Liberty. The correct fact is that "the Statue of Liberty was originally copper brown." Despite its current status as a "big green lady," the statue was unveiled in 1886 with a distinct copper-brown finish. Over the course of 30 years, the exterior underwent various "chemical reactions with the air, salt water and pollution" from New York City, which oxidized the copper and resulted in the signature green patina seen today.

Bonus Round: Smart Glove Technology

The episode concludes with a "Bonker Balls" bonus round concerning hand-tracking technology. The hosts highlight the advancements in "smart glove" technology developed by researchers at the University of British Columbia. This innovation serves multiple purposes, but its primary function discussed is "interpreting sign language and then reading it aloud through a computer," effectively translating hand gestures into spoken words in real-time. This highlights the intersection of modern technology and accessibility.

Conclusion

Two Whats and a Wow successfully demystifies complex scientific principles—such as chemical oxidation, thermal physics, and material engineering—through the lens of global landmarks. By challenging listeners to separate facts from fiction, the show fosters a curiosity about the world and the science behind the structures we often take for granted. The episode concludes with a reminder for listeners to continue exploring science through the Tinkercast platform and upcoming episodes.
