Flagman1776, Please don't consider these comments criticism; they are not, but I will impart to you some good information. Here on this board we try to promote safe ways to build and shoot cannon designed in the year 1898 or prior to that date. We don't discuss pyrotechnic materials or methods, because there are many, many boards that do that on a daily basis. It is commonly known that the quickest way to lose your right to engage in an interesting and educational hobby such as firing cannons large and small is to abuse the public at large. Local ordinances can spring up quicker than springtime tulips.
Also, we do not pay our sponsoring fees every year to discuss pyro topics. We would be very pleased to answer any question you may have about this hobby, which we consider terrifically interesting and fun.
Sincerely,
Mike and Tracy
