I never owned an Easy-Bake oven, though my younger sister did. I am still impressed that a light bulb in a fake oven can cook a real, if really flat, cupcake. I had a Thingmaker, which was a huge, heated metal box which baked plastic into molded shapes. I'll bet a Thingmaker would get one on the EPA Superfund Site list nowadays.
The Thingmaker made little green soldiers. If you failed to put a little stretched out paper-clip inside, though, the soldiers were spineless. I like to think about narratives about big machines that clone soft soldiers. If you touched a Thingmaker while it was baking plastic, you could remember its story for a very long time.
