Love yourself a good campfire marshmallow toasting session? Sure, that's sounds great! But what if you could let machines do all the work for you? That's what the folks at Evil Mad Scientist Laboratories did. This is the world's first automatic marshmallow toaster.

Too bad you can't buy one, but you can build it yourself. The design was revealed yesterday, and you can learn how to make your own. [Evil Mad Scientist Laboratories]
