MAKING A SODA-POWE RE D 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.
