Today we launched again. Our rocket launched much higher and we were very pleased with the way it turned out. In the first launch, our rocket went 20.5 meters up the air. According to the data our second launch we launched 37.5 meters. We changed almost every thing. We changed the amount of wings on the bottom from 2 to 4. We also changed the shape from a rectangle to a spike.We changed our top wings shape to a rectangle and we changed the material from balsa wood to styrofoam. We used the same amount of air and we put a little more water.
