Greek Fire is a special kind of weapon used by the people of the Byzantine Empire. It is a mixture of chemicals that burn fiercely and cannot be extinguished by water. It is like a magical fire that can be thrown at enemies and destroy their boats or weapons.
To make Greek Fire, people mixed together different chemicals like quicklime, naphtha, and sulfur. They put all these things in a special container that had a tube at the end. This tube was used to spray the mixture out into the air like a flamethrower.
The Byzantines had a big advantage in battle with Greek Fire because their enemies didn't know how to deal with it. They tried throwing water on it, but that only made it worse. So, the Byzantines held onto this secret weapon for a long time and used it to defend themselves against their enemies.
Today, we don't use Greek Fire anymore, but we do have similar weapons like flamethrowers that spray burning chemicals. We also use chemicals to put out fires, so we have learned a lot since the time of the Byzantines.
