The guys at Air Command decided to try some alternative fuels in their water rockets. Since most of these didn't have any water in them, I guess I should call them air rockets v. water rockets. They and others have previously tried flour as a fuel. This time, they went a bit over the top and used three dry fuels: finely ground bread crumbs, a candy called 100's and 1000's, and granulated sugar. They also tried Ramen-style noodle soup. As usual, the flights are well documented. The web link above has all the details and here is the eye candy (pun intended).
