00:00941 AD. A massive Rus fleet surrounds 15 Byzantine warships at Constantinople.
00:06The Rus expect easy victory.
00:08Then, the Byzantines unleash Greek Fire, the liquid that burns on water.
00:14For 800 years, this weapon terrified Byzantium's enemies.
00:17Then, the secret was lost.
00:19Greek Fire was a petroleum-based liquid projected through bronze tubes called siphons.
00:24It burned on water, couldn't be extinguished, stuck to ships like ancient napalm.
00:29The Byzantines heated crude oil from the Caucasus, mixed it with tree resin, and pumped it through a force pump.
00:35A torch at the nozzle ignited it.
00:37Result? A 15-meter jet of flame over 1,000 degrees Celsius.
00:42In 941, Prince Igor attacked Constantinople with over 1,000 boats.
00:47The Byzantines had 15 warships, but each had Greek fire projectors at bow, stern, and sides.
00:54The Rus surrounded them. Big mistake.
00:56Liquid flame poured onto the Rus' boats.
00:59Water didn't stop it.
01:00Men jumped into the sea, but the fire followed them.
01:03The Rus called it lightning from heaven.
01:06Byzantium won with 15 ships.
01:08The formula was a state secret, guarded by the imperial family.
01:12In 1204, the Fourth Crusade sacked Constantinople.
01:16The secret died.
01:17For 800 years, historians debated what it was.
01:20In 2002, scientists recreated it using crude oil, pine resin, and a bronze pump.
01:26It worked.
01:2715-meter flame.
01:28Burned on water.
01:29Unstoppable.
01:30Why didn't it spread?
01:32Byzantium lost access to Caucasus oil sources when the empire weakened.
01:36No oil.
01:37No Greek fire.
01:38But its legacy lived on.
01:39The world's first liquid flamethrower.
01:42Ancestor of modern napalm.
01:43For 530 years, Byzantium's shield, the secret that burned on water.
