Yesterday!

We mainly did review, our exam, and building rockets. For building, Juliet and I created a rocket that was about 1 1/2 feet. This is actually our rocket from today, but to get a picture of what it looked like yesterday, here's a description. One 2L bottle with fins half the size, and a very bright nose cone made of thick paper and pink duct tape! Our absolute first parachute was a 7-11 regular sized plastic bag. We cut the handles to make 4 ends to attach the string to. Our parachute seemed to be the right size compared tot he rest of our bottle. The fins were half the size of those in the picture, but the same design. If you looked at it from the bottle cap area, there would be a pocket in the shape of a V sticking out from the bottle. We assumed the air would catch in here, holding it in the air for a longer period of time. This shot up into the air, but not very high having a total of about 3 seconds. Our problem with this one was that we didn't have enough mass in the nose cone to make it shoot high, and also the parachute wouldn't deploy. This caused it to go off it's path and fall to the ground. By the time we had finished and tested this design it was time to return to class.
