In this video we’ll show how to make an AA battery.
Warning: Potassium hydroxide is corrosive, zinc is a heavy metal, and manganese dioxide is an irritant. Wear gloves when handling them.
Get a 5 mL plastic syringe (the one i got was from a company called “BD” and the catalogue number was 309603). Discard the plunger and cut off the tip. Also cut the back up to the 5 mL mark.
Get a 5 by 3 cm sheet of zinc metal about 0.5 mm thick. Cut into the 3 cm side a series of cuts about half a centimetre long. Roll the sheet so it fits into the syringe tube. Don’t roll it too tight so it falls out. It should be big enough that it stays in by friction.
Once you have the right diameter, pull it out and bend inward the tabs we cut earlier.This should now form a zinc can.
