MAKING A SODA-POWE RE D 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 nonmetallic. 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.
