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.
We have always kept the same bottles and nose cone. Our rocket is still 75 cm tall. I think the change that helped the most was the wings because with the old wings in launch 1 it was made out of balsa wood, that is still light but styrofoam is still a little lighter. Ever since we changed the rocket our group has felt better about our change because the last launch that was the real second launch and our whole rocket got fliped and the wings,nose cone and bottles were upside down. Our nose cone is always going to be the same no matter what.
