What if … you poked tiny holes in hot dogs so steam would vent in a way that the hot dog would turn itself as it heated? I was just about to try it, when I found out somebody ate the last two hot dogs! Test results await.
More adventurous would be the Self-Turning Burger. You create some packet of pop-power that you attach to each side of the burger. Like those Perdue pop-out timers, when the thingee got to the right temp, kapow, it’d explode and perfectly turn the burger over.
