The prank was the "Baghdad Battery" myth and while the build team did the prank, it wasn't their idea. Ten hand-made terracotta jars were fitted to act as batteries. Mythbusters Experiment. I think the producers just felt like 5 people to test one myth was overkill so they split the build team off and essentially gave them their own half of the show. Underpinning the baghdad bazaar iraq of Iraq, therefore, we all already know, and then spread out to be played in western countries but the baghdad bazaar iraq in areas not close to the baghdad bazaar iraq and their free market way of life and their folklore, about their grief and happiness, about dances and music, about rock and pop. On Mythbusters' 29th episode (which aired on March 23, 2005), the Baghdad battery "myth" was put to the test. I happened upon the episode of Mythbusters where they recreate the medieval Baghdad battery. My main question is; any ideas what it was used for? Baghdad battery "myth" was put to the test. By the way, theirs averaged about 0.4 volts per battery. I don't think it caused any significant bad blood. Their theories included electroplating, invoking a religious experience through electric shock, etc.
