CAMBRIDGE - NOVEMBER 25: Seven-year-old Sydney May of Erving, Mass. catches a feather with a segment of a poem attached to it at the culmination of the Rube Goldberg Machine Design Contest at MIT on Nov. 25, 2011. As the contraptions cascaded their motion into the following entry, the last one set off a string of feathers that fell in a specific order so the poem could be read aloud at the end.
