Discovering Electricity - Twitching Frog Legs

In the late 18th century, two Italian academics—Luigi Galvani and Alessandro Volta—had competing theories on what caused a dissected frog's leg to twitch.

Galvani developed a theory of "animal electricity."  In short, he thought that something inside the frog was producing the electricity which caused a frog's leg to twitch.

Volta completely disagreed, believing that whatever made the frog's leg twitch came from outside, not inside, the frog's body. 

This clip, narrated by Professor Jim Al-Khalili (from the Open University), provides background for this great debate.
