🚀 That tiny green flash before a SpaceX launch isn’t just visual flair — it’s one of the most important chemical reactions in aerospace history.
In this video, we dive into TEA-TEB, the pyrophoric ignition fluid that bursts into flame the instant it touches oxygen. It’s the reason Saturn V could launch Apollo missions, the SR-71 Blackbird could relight at extreme speed, and Falcon 9 can restart its engines again and again for landing.
From hard starts and combustion instability to Moon missions and modern reusable rockets, this is the hidden story behind the chemistry that made reliable engine ignition possible.
🔥 In this episode:
• Why rocket engines are so hard to ignite
• What causes the famous green flash
• How TEA-TEB works without sparks or igniters
• Why the SR-71 depended on triethylborane
• How Saturn V trusted it on every Apollo launch
• Why Falcon 9 still relies on it today
• And why a tiny amount of this chemical can decide whether a rocket flies at all
If you enjoy space, engineering, chemistry, and the overlooked details behind legendary machines, this one’s for you.
