"☂️ A sting on Waterloo Bridge. A stranger with an umbrella. A death that exposed one of the most terrifying poisons on Earth. In this video from Kaboom, we trace the full story of ricin — from the castor oil plant grown around the world, to the 1978 assassination of Georgi Markov, to Cold War weapon research, terror plots, and the disturbing reality that there is still no approved antidote. You’ll see how ricin works at the cellular level, why even microscopic amounts can be deadly, how it became infamous in intelligence operations, and why scientists still struggle to stop it once it enters the body. Topics covered include: • Georgi Markov and the umbrella assassination • The biology of the castor bean plant • The discovery of ricin in 1888 • Paul Ehrlich and ricin’s role in early immunology • How ricin destroys ribosomes • U.S. and Allied military experiments • KGB poison labs and Cold War covert weapons • Ricin letters sent to U.S. presidents • Modern vaccine research like RiVax • Why ricin remains a major bioterror concern If dark history, toxicology, covert operations, and real-world science fascinate you, this one is for you. 👍 Like the video if you want more stories like this 💬 Comment what poison, assassination method, or secret weapon Kaboom should cover next 🔔 Subscribe for more deep dives into the deadliest stories in history #ricin #GeorgiMarkov #ColdWar #assassination #poison #history #truecrime #bioweapon #toxicology #Kaboom ricin, georgi markov, markov umbrella, umbrella assassination, cold war assassination, castor bean poison, castor oil plant, kgb poison, laboratory 12, soviet intelligence, bulgarian secret service, todor zhivkov, waterloo bridge, bbc, radio free europe, toxicology documentary, deadly poisons, bioterrorism, ricin antidote, rivax, poison history, covert operations, secret weapons, historical mysteries 00:00 Intro 01:04 Ancient Castor Plant Origins 02:54 Discovery Of Ricin 04:12 Ricin And The Birth Of Immunology 05:28 How Ricin Destroys Cells 08:27 Military Weaponization Attempts 11:24 The Assassination Of Georgi Markov 16:43 Ricin In Modern Terror Plots 20:34 Vaccine Research And No Antidote 23:01 Why Ricin Is So Hard To Stop 25:39 Ricin’s Lasting Global Threat 26:31 Outro The Poison With No Antidote — The History of Ricin - YouTube https://www.youtube.com/watch?v=kdVI6xHPMng
