Making Sorbitol Rocket Candy + testing concrete nozzles

Testing 4 solid rocket engines. 3 of them use the 65/35 KNO3/Sorbitol + 1g Fe2O3/1cc Glycerin recipe shown by Tech Ingredients in    • DIY Rocket Engines - Easy and Cheap!  . He has made a more thorough video of the r-candy-cooking process, a great video, and a definite must-watch. Tech Ingredients:    / techingredients   Sorbitol is a much faster and safer substance to make the r-candy from than regular table sugar. Would definitely recommend it over the latter one. The fourth engine used the same recipe but I added around 2g of AL powder. That reduced the burn rate and made the propellant solidify much faster. All of the rockets had a nozzle made of concrete, will soon make a video showing how I made mine. The nozzles definitely could be better but it's a fast and pretty cheap way to produce them. Propellant masses: 1. 250g 2. 350g 3. 250g 4. 380g
