an improved version moving away from fruit power to liquid acid power. Any acid will work, such as soda, water, that stuff that eats through your flesh when you spill it on you, or anything else that is acidic.

Step 1: Materials & Tools
to make this battery, you need:
1 plastic shot glass
Step 2: Prepare the Shot
use the knife to make a cut a little over the bottom of the glass, but not that low.
Step 3: Insert the Electrodes
the electrodes are the zinc and copper. Bend them so that they reach down about the length of the bottom to the cut. Then place the bent part in the hole and push up, and the long piece should be pointing forwards. then, add acid.
to increase voltage, make a second one and tape the zinc of one to the copper of another. The voltage will increase by an even interval every time.
