Chain Reaction Ice Cream Server

You've never seen a Rube Goldberg contraption like this one! It just keeps going and going, throughout the house, using some rather weird elements that I wouldn't want to test, much less rely on. For example, I have never met such a well-mannered and reliable Roomba. Maybe it was the expensive kind. And you'd think testing the world's slowest soap bar would wear it out. He must've bought dozens of them. Having Siri and Google Assistant talk to each other was a nice touch. Professional chain reaction guy Steve Price, aka Sprice Machines spent four months designing, building, and testing this chain reaction. (via Geeks Are Sexy)
