Wow TIL, the ancient Egyptians knew how to harness hydrogen gas! /s
Supposedly the Egyptians did know how to make a simple battery. Mythbusters reproduced the battery and it produced around 4 volts. It only takes 1.5 volts to produce hydrogen gas from water via electrolysis. It's technically within the scientific capability of the Egyptians to do this, although I don't think it likely.
