Can you believe that 2,000 years ago people had already invented the battery?

 

Some historians believe this to be true after an artifact was discovered near Baghdad in 1936 which can actually produce voltage when an acidic agent was added to it (lemon juice, grape juice, vinegar).
Some people believe that these batteries were used to electroplate items with thin layers of gold, while others believe that these artifacts are just a coincidence and not meant to actually produce any kind of electrical charge. The one thing that we do know for sure is that when this clay jar is filled with vinegar (or another acidic solution), it produces about 1.1 volts of electricity.

Whether or not people discovered electricity 2,000 years ago, we may never know for sure, but it’s still fascinating to think that it could be true..
