Step 2Finish the paper roll
When the glue has dried, the roll of paper will be firm like cardboard. Add a wooden plug to one end of the paper roll. Use a 3/8 inch dowel for this. Cut 3/16 inch from a dowel rod. Smear it with glue and insert it into one end of the roll. Allow the glue to dry thoroughly.
Get a thin brass rod or a short piece of #10 bare copper wire. Drill a small hole in the center of the wooden plug and press the copper or brass piece into the hole.
Place the roll over an AAA battery. File the brass or copper piece until the length of the AAA battery with the paper adapter is the same length as an AA battery.
