Last week Troy came to our school to talk about the thrust, weight and how the rocket drags. Troy is an engineer who is part of the Wonder Project. He goes to different schools and teaches them about rockets too and this time he is at our school. He normally has a buddy called Gustavo but he was looking after his wife. When the rocket flies it is using thrust but when it runs out of thrust and starts coming down that is because of the weight. After he finished talking about the weight and thrust we went over to the field and launched a rocket made from a plastic bottle. When we launched it for the first time we only put it on 40 psi and it didn’t fly that high. Then we did it on 60 psi and it flew as high as the goal post. I really enjoyed this and I can’t wait until we make our own rockets. Have you ever done the Wonder Project before? Here is my rocket design
