"Bottle Rocket" Me and my science partner are making a bottle rocket, if u need some tips well ill tell you if your in the B division which is the middle school Science Olympiad team. last year i won state championship for battery buggy. but now this year is bottle rockets so what i have done is taken a 1-liter bottle and added 3 wings to it, and you need to make all wings equal in size so there will be an even amount of aerodynamics. so basically thats all you need to do and also the angle of the wings need to be at the most by 50 degrees on a triangular fin.
