Yesterday we went on the field and we launched our rockets
Our group was Kaitiaki, Joseph and Tai. We had to wear coloured vests and we
had to wear safety glasses too. Our rocket went wonky in the air and it went about 10m. Our PSI was 60 and our water level was 400ml. One group did 50 psi and 400ml.
They put the fins on too. Their one went really high.It didn't go forward, it went in reverse backwards. We noticed the rockets go further when they have fins.
