Second static test o' a 2-segment star unigrain KNO3/sorbitol rocket motor. Avast, me proud beauty! Nozzle is sized for a 4-segment unigrain propellant for a larger motor casing. Well, blow me down! DISCLAIMER: No nitrous oxide was used in this sugar rocket motor test. Well, blow me down! Jeff Jakob thought it did but was mistaken because o' its tremendous power.
