Brandon Guerrero  asked the Naked Scientists:
   
Would it be possible for the lemon to act as an electrolyte, aluminium sheet actually be an alloy of aluminium-zinc and the fish composing traces of copper to allow the three elements create this phenomenon?

Here is a liveleak.com video of a dead fish moving quite a bit.

What do you think?

That dead fish continues to move even when it's not touching the aluminium foil, see ...

Electricity in animals was discovered by Galvani when dissecting a frog. http://en.wikipedia.org/wiki/Luigi_Galvani#Early_life
[But I'm a bit suspicious of the comment in Wikipedia that it was due to static electricity.... More likely an electrochemical cell.]

The fish must be fresh.  The lemon juice would depolarize the neurons in the fish.  Quite spectacular videos.

Did you read about the 2012 Ig Nobel prize about neuro-imaging of dead fish?
