    Researchers for the first time apply catalytic chemical reactions to 2D sheets to generate flows that transform these sheets into mobile, 3D objects. The “magic carpet” featured in tales from “One Thousand and One Nights” to Disney’s “Aladdin” captures the imagination not only because it can fly, but because it can also wave, flap, and alter its shape to serve its riders...
