Sugar rocket

Here is a small model of a rocket (about 25cm tall) that actually works! The small hole in the inside wall is there for future upgrades (such as a parachute). To make it fly you will need potassium nitrate (KNO3) which is a stomp remover, sugar and a 4-5mm rod to guide the takeoff. Mix the two components (about 70% potassium nitrate and 30% sugar) and press them into the rocket using the tool provided in the files, if you can it would be optimal to grind it finer with a coffe grinder; 2. When the mixture is compact use a 5-7mm bit to drill a hole into the motor (almost full length); 3. Now glue in place the nozzle and the nose cone; You are ready to fly! IMPORTANT Mixing potassium nitrate and sugar can be very dangerous do it only if you know what to do or you are supervised. The nose cone MUST be printed with 100% infill, at least from 25mm to full height, otherwise the rocket will be unstable and spin out of control, i included the optimal sliced files for the A1 mini
