Launch Day #3: Test of 3 Seconds

Today was our third launch day. The requirements were a launch that was three seconds minimum including a parachute. Using this website: http://lnhs.org/hayhurst/rockets/ we created the parachute for our rocket. We also made better fins using this website. For our nose cone, we used a cone and cut it so it just fits over the top of the bottle and attached it on the inside of the bottle with tape. When we launched our rocket, we were very scared it wouldn’t work. Surprisingly our launch lasted seven seconds! It would’ve been eight but it accidently landed into the back of some teacher’s truck. We noticed that Kory and Pono’s rocket went super high and lasted ten seconds. Rachelle and I think that if we put a little more water, as well as air pressure that our rocket will last ten seconds and we won’t have to make any changes.
