"Chemical origami" shrinks 2D discs into 3D objects
Physicists in Israel have invented a neat method of making elaborate 3D structures from flat 2D discs. The trick is to pre-treat a gel disc half the size of a beer coaster with a monomer solution "blueprint" that selectively shrinks when heated. The technique, which cleverly demonstrates the link between 2D and 3D geometry, could be used by engineers to create self-assembling prototypes.
