It's eerily reminiscent of the T-1000 from Terminator 2 – though unlike the killer robot's "mimetic polyalloy," this gallium and indium alloy can't copy Robert Patrick's form and stalk around menacingly.
Liquid Magic
What it can do, however, is conduct electricity – opening up the possibility of bendable electronics encased in rubber. In principle, it can also create self-healing wires.
Liquid at room temperature, the metal is squeezed out of a syringe, developing an oxide skin when exposed to the air and allowing for the creation of structures. Converting a 3D printer to pump out the magical liquid shouldn't be too hard, but at around 100 times the cost of 3D printing plastic, it'll be a long while before we're creating our own flexible electronics.
