Dorothy's school assignment was to invent something and make a model. She invented the "Wifi World Truck," a wifi-enabled car, so that she can watch YouTube on road trips. She showed off her model in what turned out to be a 6-minute video tour, but I have shared here the first 30 seconds -- this intro was her brainchild.
