Chemical origami

Physicists in Israel have invented a neat method of making elaborate3D structures from flat 2D discs. The trick is to pre-treat a gel dischalf the size of a beer coaster with a monomer solution "blueprint"that selectively shrinks when heated. The technique, which cleverlydemonstrates the link between 2D and 3D geometry, could be used byengineers to create self-assembling prototypes.
