Make a Small Charge Battery

Ever want a little light but can't find a flashlight or a battery? Here's how to solve that problem.

Steps

Gather the supplies needed for construction.
Cut the foil into circles the size of the quarter.
Cut the blotting paper into circles bigger than the foil or coin.
Dissolve and mix the 2 tablespoons salt into the vinegar.
Use the masking tape to attach the end of one of the wires to the underside of a foil disk.
Next, stack in the following order: foil, paper, coin, foil, paper coin. Each foil/paper/coin combination is a tiny battery, yet it will take quite a few of these to light even an LED (light-emitting diode).
Place one wire on the topmost quarter, which will be the positive terminal and bottom of the battery, the aluminum foil, which will be the negative terminal.
Connect the wires to the correct spots on the light bulb or LED.
Finished.
