Galvani realize that finishing a circuit interfacing disparate metals to the legs of an as of late departed frog would make an invigorating electrical current.
The subsequent electrical flow would invigorate the frog's legs to bounce, and with rehashed upgrades he could make them dance.
Note: But in those times, bringing a dead frog "back to life" was a stunning and horrendous "supematura " accomplishment. (What's more, Galvani adored it!) *
