Today Young Grasshopper set about repairing earlier soldering efforts on their prototyping board, using the soldering iron they recovered using citric acid and a scrubber. They learned how to control 2 LEDs off one pin, and reviewed resistor codes. They learned to friction cut plastic with paracord, and then made a bolas/poi to demonstrate centripetal force and conservation of momentum. Nobody got whacked, but we wrecked a bush.
