Reusable L Class Sugar Rocket Motor

As a Freshman at MIT, I was interested in designing and building a high power solid rocket engine in order to launch larger rockets. Since I only had my dorm room as a lab space, I decided to use a sugar and potassium nitrate propellant mix, which is significantly safer and cheaper than other propellants. Still, if I got caught there's a chance MIT would let me keep working just like a similar group of students at CalTech in the 30s. The engine was successfully static fired and was reusable immediately after the test.
