: My 9 yr old son has signed up to do a science report on batteries.  I was
: wondering if anyone could provide me with some information as to how to
: construct a home-built battery.  In my grade school days, I remember seeing
: the 'ice cube tray' version, but I don't remember what to use as a good
: electrolyte or what the easily obtainable metals were.  

: Thank you in advance.

The simplest one is easy.  Take a lemon or other citrus type fruit, and
stick a pair of metal strips into it for the contacts.  The two strips must
be of disimelar metals like copper and zinc.  Then connect a voltmeter to
the contacts and read the voltage.
