Today in class I started to make a rocket engine. What we used to make is a PVC potassium nitrate and table sugar. We put in a beaker and placed it on a hot plate until it got mushy. Then we put it in the PVC pipe right away because it dries quick. After we put it in the PVC pipe we let it dry for like five minutes and added cement at the. After that we let the cement dry for two days and then we set it off.
