Did Ancient People Have Electricity 2,000 Years Ago?! ⚡ #ancientengineering

Could an ancient clay jar really have produced electricity? The mysterious Baghdad Battery contained a copper cylinder and an iron rod — and replicas of the basic arrangement can generate a small electrical voltage when the right liquid is added. But was it actually an ancient battery? We still don't know. Then there's Roman concrete. Nearly 2,000 years later, some Roman structures are still standing, and scientists have discovered that their concrete could actually **partially heal its own cracks**. Ancient technology keeps getting stranger. These are no.8 and no.7 in our countdown of ancient technologies that seem almost impossible for their time. And no.6? It's a legendary material whose original manufacturing tradition largely disappeared. Subscribe to The Fun Tech for Part 3. #BaghdadBattery #RomanConcrete #AncientEngineering #Shorts
