We had both always wanted to build a Rube Goldberg machine but never had a good reason to and we could also never find anyone else interested in spending a lot of time and energy building a machine that is basically pointless. This was the perfect opportunity! We spent about 30 hours building it and the result is a process that lasts about 30 seconds. Time well spent, I believe."
