Our initial prototype was constructed using cardboard, hot glue, and toothpicks. We created a works-like model of the Geneva mechanism and tipping subsystem, as this was the one we anticipated the most issues with. The prototype consisted of the slot gear of the Geneva mechanism, a ball and hook to catch and turn the bottle, and a stand to hold it all together. In the end, we chose to move forward with a different method of tipping the bottle because of space constraints, but the prototype did help us to visualize how the Geneva mechanism would work.
