After our third business meeting, Ada Space President Jaimee Lindvay gave instructions on how to create our own batteries using pennies, zinc washers, aluminum foil, electrical tape, and vinegar. She explained “the zinc has some extra electrons the copper penny is happy to take creating current when completing the circuit with an LED.”  We then tested our batteries and made hypotheses about why some batteries were stronger than others. We discovered that the more layers of pennies and washers that were stacked, the stronger the battery was. Learn how to make your own.
Next, everyone turned to the workbench. Jaimee gave a soldering demonstration and we made wire bracelets for those who wanted them.
