100 Objects #4: Lowe's Gas Bag

In 1861, one man and a “gas bag” filled with hydrogen sparked America's obsession with going higher, farther, into the unknown. In this episode, Roman and journalist Jack Hitt tell the story of Thaddeus Lowe — showman, scientist, and dreamer — whose balloon flight from Cincinnati went wildly off course and straight into the Civil War. Lowe pivoted to create the US military's first aerial reconnaissance unit, a precursor to the Air Force, and today his legacy spans generations— stretching all the way to the dark side of the moon.

100 Objects #3: The Pension Files

What do Civil War pension files reveal about one of history's most successful slave rebellions? Historian Edda Fields-Black joins Roman to trace a story of fire, flight, and freedom — beginning on a South Carolina rice plantation in 1863, where a Union raid liberated over 700 people in a single night. By unearthing Black soldiers' testimonies buried in military pension applications, they resurrect not just the raid, but the lives and communities it transformed.

100 Objects #2: 60-Degree Screw

In the early 20th century, nothing quite fit — fire hoses couldn't connect to one another, football teams played with different balls, traffic lights meant different things in different states. Then World War II exposed the deadly cost of incompatibility, and the US quietly imposed a single solution on production lines across the world: the 60-degree screw. Roman Mars and historian Daniel Immerwahr tell the story of a hidden industrial empire, built one standard at a time.
