A major breakthrough in ridiculousness.

Everyone familiar with 3D printing agrees that the technology has the potential to change our world in ways, both good and bad, that we can't yet imagine. One of the downsides that everyone predicted is the prevalence of homemade guns. However, I don't think anyone imagined that one of the weapons created would be a machine gun that folds and shoots paper airplanes. Why would they? It's a ridiculous idea. That didn't stop YouTube user Papierfliegerei, though, because he not only thought of it, he designed the parts and had them fabricated through the German 3D printing website For better or worse, the paper airplane machine gun is now a reality.
