battery power

Question: Will a home make battery work with a home made battery?
Hypothesis: I think the calculator will work.
equipment: two cups, 4 wires, a battery powered calculator, vinegar and two galvanised nails (zinc) Method: first the vinegar is pored into the two cups. Now put one end of the wires into vinegar in both cups. Now I connect both nails to of the wires. Now connect the two cups with one nail wire and normal wire. Finally the wires connect to the calculator and then watch. observation: I swore that the calculator turned on when the wires were connected. explanation: The nail reacted to the vinegar and the wire reacted with the vinegar that charged up the calculator to make it turn on.
