Two weeks ago I posted about me and some fellow aerospace students experimenting with rockets. At the end of this post I had a picture of four rocket engines, at a family reunion this weekend I shot them off. Unlike last time I can post these on Youtube with no editing. I will not go a big rant; I will just post the videos (note I have not posted them in order of when they were launched rather based upon how well they launched).
My sugar fuel had to much sugar so it acted more as a smoke bomb with a lot of flame, I think the second sugar rocket lifted of because of a bit of black powder I had in it. I estimate that my second black powder rocket hit around 200-300 ft.
