Jello shots are basically nature's way of sneaking alcohol into your system without it noticing right away. And now Jeroen Domburg of SpritesMods has built a 3-D printer that can print basic shapes inside of them. They're sure to be a hit at your next sausage party. PI KAPPA DELTA RULES.
Basically, the 3D printer's design was based around a couple old CD-ROM drives Domburg had lying around. By stripping the stepper motors from the drives and putting them together, he was able to create a single contraption able to move a shot glass along three axes.
A syringe, a bit of tubing and a few more salvaged CD-ROM parts and Domburg had a working 3D printer capable of printing food dye into existing Jello shots.
So basically, with a syringe and some food dye you can do the same thing freehand. Alternatively, just drink a beer. If you're feeling really creative maybe use your finger to draw a design in the foam on top. You put your finger in my beer though and I will beat you with a bar stool.
Keep going for a brief video of the 3-D printing in action.
Thanks to Robby, who doesn't drink Jello shots anymore after a fateful night of rainbow vomit.
