Magnetic liquid marbles capable of hosting both aqueous and organic fluids may serve as new miniature chemical reactors. Chemical reactions can occur either within a single liquid marble or between two magnetic liquid marbles (as illustrated). The liquid marbles can also interact with external devices simply by opening and closing the powdery shell under a magnetic field.
