Our task was to create and test a rectangular martini mixer. We came up with several designs and had a prototype made of one of them. We designed a special top with a built-in Bluetooth thermometer, removable fill spout, velcro strap, and attachment for an automatic shaker machine. This special top was used to collect test data in order to improve the design. This project is still a work in progress and additional prototypes are currently being manufactured in a factory in China.
