Exploring Biological Wonders and Metallic Mysteries: A 'Wow in the World' Special

In this episode of the popular science podcast Wow in the World, hosts Mindy Thomas and Guy Raz guide young listeners through a blend of exciting program announcements, biological trivia, and hands-on chemistry experiments. The episode centers on their trademark game, "Two Whats and a Wow," which challenges listeners to distinguish scientific truth from clever fabrications.

The Anatomy of a Swallow: How Frogs Eat

The show began by resolving a lingering scientific question from the previous episode: how do frogs manage to swallow their food? The answer is a fascinating biological adaptation. Frogs utilize their eyeballs to assist in the swallowing process. After taking a bite, a frog will blink, and this movement forces the eyeballs down into the top of its mouth, effectively squeezing the food down its throat. The hosts contrasted this with human blinking, which serves to keep eyes "hydrated" and protected from "dust particles," and clarified that while some might think chinchillas blink one eye at a time, it is actually a trait observed in hamsters.

The Science of Oxidation: Operation Greenify Your Money

Transitioning from biology to chemistry, the hosts introduced a segment on metals and the process of oxidation. They challenged listeners to perform a home experiment called "Operation Greenify Your Money." The experiment explores how copper reacts when exposed to environmental factors, similar to how the Statue of Liberty transformed from its original reddish-brown color to the iconic green seen today.

By using pennies minted before 1982—which contain a higher concentration of copper—listeners are encouraged to create a chemical reaction using vinegar and salt. This process, known as oxidation, demonstrates how chemical interactions can alter the physical appearance of metals over time. This hands-on approach reflects the show's mission to help "wowzers" (the show's nickname for its young audience) learn about the world through exploration and play.

Scientific Trivia: The Mystery of Metals

The episode concluded with a new round of "Two Whats and a Wow" focused on the category of metals. The hosts presented three intriguing statements for the audience to ponder:

  1. Earthquakes can turn water into gold.
  2. In ancient Egypt, copper was used to dye hair orange.
  3. Olympic gold medals are actually made of bronze and coated in 24-karat gold.

Listeners were tasked with identifying the single "true scientific wow" among these claims, encouraging them to engage in critical thinking and research before the reveal in the next installment.

Looking Ahead

Beyond the science, the episode served as a platform for several announcements regarding the Wow in the World community. Mindy highlighted upcoming guest appearances, including characters from Circle Round and Sesame Street’s Elmo, as well as an upcoming 250th-episode musical celebration. These segments emphasize the show’s commitment to fostering a community of curious learners, supported by their new line of science-based toys and interactive playbooks, all designed to keep the spirit of wonder alive for children and adults alike.
