A chemical so dangerous it made concrete burn.

Today on Kaboom, we dive into the unbelievable history of chlorine trifluoride — the pale green liquid that N**i Germany wanted as a weapon, American engineers tested in rocket engines, and industry learned to fear for very good reason. From a one-ton spill in Louisiana that burned through concrete and gravel, to underground wartime bunkers and Cold War propulsion experiments, this is the story of a substance so reactive that even ash, sand, and asbestos can become fuel.

If you like terrifying science, forgotten history, and disasters that sound impossible but really happened, this one is for you. ☣️🔥

⚛️ Francium is the most reactive metal scientists know of... and yet no one has ever watched it react.

In this episode of Kaboom, we dive into the bizarre story of element 87 — the last naturally occurring element ever discovered, one of the rarest substances on Earth, and a chemical ghost that decays almost as soon as it appears. From Mendeleev’s prediction to decades of false discoveries, this is the wild hunt for francium and the overlooked scientist who finally proved it was real: Marguerite Perey.

You’ll learn why francium is believed to be even more violent than cesium, why it’s almost impossible to study, how only tiny numbers of atoms have ever been trapped, and how its discovery changed the periodic table forever.

🔬 In this video:
• Why francium should be the most explosive alkali metal
• The 70-year search for element 87
• The false names: russium, alkalinium, virginium, and moldavium
• Marguerite Perey’s breakthrough in Paris
• Why francium is so rare and unstable
• How modern physicists trap and study it with lasers

If you love chemistry, physics, radioactive elements, and strange true stories from science history, this one’s for you.

Hydrofluoric acid looks deceptively ordinary on paper. In reality, it dissolved glass, poisoned generations of chemists, and helped earn fluorine the reputation of chemistry’s “savage beast.”

This episode follows the deadly path from Schwanhard’s etched spectacles and Scheele’s catastrophic lab habits to the fluorine martyrs, Henri Moissan’s breakthrough, and the shocking reason this same acid is still essential to modern life. From Nobel-winning chemistry to nuclear weapons, Teflon, refineries, and the microchips inside your phone, this is the story of one of the most dangerous substances humans ever learned to use. ⚗️☠️📱

A forgotten patent. A camera company in Tennessee. A chemistry professor with zero explosives experience. And somehow, all of them helped create the most important military explosive of the modern age.

This video tells the incredible story of RDX — the white crystalline compound that outclassed TNT, powered the Dambusters raid, helped destroy U-boats in the Atlantic, sank the Tirpitz, and even played a key role in the implosion system of the first atomic bomb.

From accidental discoveries in German labs to mass production in World War II, this is the strange, hidden history behind the explosive that changed warfare forever.

From a cellar full of rotting urine to matchboxes, factory floors, labor revolts, and modern battlefields—this is the unbelievable history of phosphorus.

In this video, Kaboom traces how a failed attempt to make gold led to the discovery of an element that glowed in the dark, changed everyday life by making instant fire possible, and then became one of the most infamous industrial poisons of the 19th century. From Hennig Brand’s bizarre experiment in 1669 to the rise of white phosphorus matches, the horror of phossy jaw, the Matchgirls Strike, and the military afterlife of “Willy Pete,” this story is as brilliant as it is brutal.

Expect chemistry, industry, labor history, medicine, and warfare colliding in one of the strangest true stories ever told. ⚗️🔥

From a paint workshop in Berlin to gold mines, battlefields, spy gear, and one of history’s darkest crimes — cyanide has shaped the world in ways most people never realize.

In this episode of Kaboom, we trace the astonishing history of cyanide: how a failed attempt to make red pigment accidentally created Prussian blue, how chemists uncovered the deadly gas hidden inside it, and how that same molecule moved through art, industry, war, agriculture, and mass death.
