Never underestimate common objects

   I'm quite awe by how everyday household objects ( well except cola since I love drinking water xD ). You are able to make a successful battery that make your LED light O_O  ( stands for light emitting diode) .   You need the following items cola or in American terms coke  , coins , a cup with salt and aluminum foil .  It will work  
probably about 2 volts and only a few milliamps, but its still can't pass those companies that sell batteries commercially ( obviously )
Credicted to 99media
  I heard there's  another method which uses lemon to make the batteries.
