How dribbling glass gets 'stitched' into shape

A collaboration at the Massachusetts Institute of Technology (MIT) has produced a "sewing machine" for molten glass.

Engineers who pioneered 3D printing of glass worked with a mathematician who knows all about the dynamics of liquid threads.

The repeating shapes created by wobbles in the dribbling glass can be controlled, they found, simply by adjusting the speed of the nozzle.

These waves and loops then become the building blocks for intricate, 3D objects.
