3D printer that draws pictures in jello shooters

Jeroen Domburg's friend was having a 25th birthday party at which jello shooters were to be served. Jeroen decided to liven these up by creating a 3D printer that inserted a needle into each shot and injected an ink made from banana liquor, food colouring and corn starch in 3D patterns like cubes and spirals. Even cooler: the main body of the electronics in the printer were harvested from superannuated DVD and CD drives, and the firmware for the printer is free software (TGZ) for your pleasure.

  1. Pretty neat, horrid youtube comments. I liked the suggestion about doing this in clear epoxy for cool art designs.

  2. Does anybody know if the protease enzymes that cause certain fruits to be jello-incompatible are merely capable of preventing it from setting or whether they can disrupt a partially or wholly set collagen matrix?

    If it's the latter, you could theoretically 'print' fairly complex voids in an otherwise continuous gelatin block (presumably, you'd want to do the injecting mid/late in the setting process, so the needle holes will heal; but the areas injected with protease enzymes will remain fluid and can either be drained, if connected to the outside, or replaced by injecting the desired filler if they are sealed voids).

    I'm not quite sure why you would want a chunk of jello that has a complex internal channel structure; but I suppose that replacing plebeian jello shots with transparent fluidic logic blocks capable of mixing the correct beverage ratio for a given cocktail automatically would assure your permanent position in the lore of geeks getting shitfaced... It would also look pretty cool, especially if you used undyed gelatin with distinctively colored beverage components...
