People ask if Tommy Boy was based on our family. It was. During the summers Chris would travel on the road with his dad in Wisconsin. Every family has that kid that entertains everyone. Chris was ours. God, we were lucky!
@smartereveryday I am an engineer that helped publish a couple papers on shock tube experiments. It is a pretty interesting field that is not very well known. Your cannon could be retrofitted very easily. Let me know if you are interested. I can send you some white papers.
