Among the challenges were powering a small radio with a battery made out of fruits and vegetables. Groups of scouts experimented with series and parallel circuits, and one group used a total of 8 potatoes and apples to get almost 12 Volts out of the system!

Groups also tried out the Marshmallow Challenge.
Using just 20 strands of spaghetti, 1 meter of masking tape, and 1 meter of string, teams must build the tallest free-standing structure that can hold the marshmallow on top!
