3D Printing Conductive Food

Professor Marc in het Panhuis of the ARC Centre of Excellence for Electromaterials Science decided to take on a fun project in seeing if it would be possible to use Vegemite as a 3D printing material that could use its naturally conductive qualities to light up LEDs. He tried it both in the conventional way for completing a circuit, as well as after 3D printing the Vegemite onto bread, using it to power an LED--and eating the bread as a snack afterward.

Great invention! But what would it be like, we will be electrified when we eat that bread? :D
