Why doesn’t TNT explode in a fire? Why can C4 burn like fuel without detonating? In this episode, Kaboom dives into the hidden mechanism behind almost every modern explosive: the explosive train.

From gunpowder and flintlocks to mercury fulminate, percussion caps, Alfred Nobel, nitroglycerin, and dynamite, this is the story of how humans learned that the only reliable way to set off a big bomb… is with a smaller one first.

💥 In this video:
• Why secondary explosives usually burn instead of detonate
• The crucial difference between fire, impact, and shockwaves
• How mercury fulminate became the first practical primary explosive
• The duck-hunting minister who helped revolutionize fi****ms
• How Alfred Nobel turned deadly chaos into controlled blasting
• Why blasting caps changed mining, war, construction, and industry forever

What started as an alchemist’s accident ended up transforming weapons, engineering, and even the creation of the Nobel Prize.

If you enjoy history, chemistry, military technology, and the strange chain of discoveries that changed the world, this one’s for you.

💥 The explosive that was supposed to change warfare in 1987 almost disappeared before the world needed it most.

This video dives into the story of CL-20 — the ultra-powerful explosive first developed at China Lake, California, by chemist Arnold Nielsen. More energetic than HMX, faster than TNT, and capable of giving tiny warheads devastating pe*******on, CL-20 looked like the future of military explosives. But sensitivity, manufacturing problems, cost, and post-Cold War priorities pushed it into the shadows.

Then Ukraine changed everything.

From desert labs and crystal engineering to Chinese mass production and modern drone warfare, this is the hidden history of the molecule that may define the next era of battlefield power.

⚡ In this video:
• How CL-20 was invented
• Why it outclassed TNT, RDX, and HMX

🔥 Water can put out most fires. Thermite is not most fires.

In this video, we dive into the shocking chemistry of thermite — the infamous aluminum-and-rust reaction that burns hotter than lava, melts steel in seconds, and can’t be stopped with water, foam, CO₂, or even a lack of air. Once it starts, the only option is to get back and let it finish.

But thermite’s story is bigger than the reaction itself.

From Hans Goldschmidt’s Berlin laboratory in the 1890s, to rail welding that still holds modern train tracks together, to incendiary weapons used in both world wars, this is the history of one of the most dangerous and fascinating reactions ever discovered.

In this episode from Kaboom, you’ll learn:
⚙️ Why thermite carries its own oxygen
💧 Why water makes it even worse
🌋 How it burns far hotter than lava
🛤️ Why railroads around the world still use it
💣 How it became a weapon of war
🧪 The science behind the Goldschmidt process

If you enjoy stories where chemistry, engineering, and history collide, this one is for you.

💥 Tritium is one of the rarest substances on Earth — and one of the most important. In this video, we trace how a nearly invisible isotope of hydrogen went from an obscure lab discovery to the material that helped make hydrogen bombs possible, powered the deadliest nuclear tests ever conducted, and may one day fuel fusion reactors.

From Rutherford’s experiments in Cambridge to Ivy Mike, Castle Bravo, Savannah River, and modern tritium production at Watts Bar, this is the story of the tiny radioactive gas that changed nuclear history.

Inside this episode:
☢️ Why Castle Bravo exploded far beyond predictions
🌊 How Bikini Atoll became the site of a historic radiological disaster
🧪 What tritium actually is and why it matters
🚀 How boosted fission and thermonuclear weapons depend on it
🏭 Where the United States gets tritium today
⚡ Why future fusion energy may depend on solving the tritium shortage

Tritium is easy to overlook. But without it, much of the modern nuclear world would not function the way it does.
