MAKING A SODA-POWE RE D BATTERY
Sand the aluminum strip (optional).
• You can skip this step if you bought the aluminum from a hardware store. If you cut
the strip from a soda can, you’ll need to sand off the coatings (i.e. paint, plastic) on
both sides of the strip.
Place the strips into the solution.
1. Ensure that the strips do not touch each other. Place them across from each other
— not side by side or overlapping — in the cup. Ideally you’ve cut the strips long
enough that their tops sit above the soda, extending slightly past the rim of the cup.
2. If the strips do not extend past the cup’s rim, you can bend each strip lightly so that
it hangs off the edge of the cup
