2. MAKING A SODA-POWERED BATTERY
• Gather your materials. For this battery you will need one unopened can of
soda (any type will do),one plastic cup (6 to 8 ounces),and one 3/4-inch-wide
strip of copper that’s slightly longer than the height of the cup.In addition,
you’ll need a pair of scissors,a voltage meter,and two electrical lead wires
with alligator clips at both ends.If you don’t already have these materials
around your house,you can purchase them at a hardware store.
• You can substitute the copper strip with several pieces of copper wire stuck
together or bent in a zig-zag fashion to reach the desired width.

3. MAKING A SODA-POWERED BATTERY
• Fill the plastic cup roughly 3/4 full with soda.
• Note that the cup doesn’t absolutely have to be plastic.It just has to be non-
metallic.Styrofoam and paper cups will also work.
• Make sure the soda can is completely empty. Discard (or drink) any
soda that remains in the can.Turn it upside down in the sink and give it a few
extra shakes to make sure that all the soda is out.

4. MAKING A SODA-POWERED BATTERY
Cut a strip of aluminum from the soda can.
1. Cut a 3/4-inch-wide strip from the side of the soda can.Ensure that’s it’s
slightly longer than the plastic cup’s height;if this isn’t possible,don’t worry —
you can just bend the top of the strip and let it hang over the edge of the cup
and into the fluid.Instead of cutting the can,you may purchase aluminum strips
from a hardware store.
2. Aluminumfoil is not an effective replacement for an aluminum strip;don’t use
it!

5. MAKING A SODA-POWERED 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

6. MAKING A SODA-POWERED BATTERY
Attach lead wires to metal strips. Attach one lead wire to one metal strip by
opening the alligator clip and closing it on the strip.Then,attach a differentlead
wire to the other metal strip,again using the alligator clip.Be careful not to let
the alligator clips touch the soda.
It doesn’t matter which color of wire attaches to which strip
Test the battery.
• Following the instructions that come with your voltage meter,connect a lead
wire from each metal strip to the voltage meter.The meter should read your
battery’s voltage at roughly 3/4 of a volt
