What is a Pop Bottle Rocket?
A pop bottle rocket uses a 2L pop bottle, which then, you fill up the 2L pop bottle with water, and then with air, air pressure is created, and when you launch it Newton’s law happens. A lot of people put designs on their rockets, such as mine I did not leave it plain, I added cardboard, fins, color, nose etc. To make the rocket fly high and far away, you have to understand on how to make your rocket aerodynamic. Below this is an example on how a water rocket can be launched.

Observations from prototypes:
(Prototype rockets are much smaller and use 500ml pop bottles)
I tried to make my prototype rocket have a pointy nose, just because it can be aerodynamic, pointy nose rockets fly great, it’s just after the rocket has crashed nose down, it will fail to protect the egg because the landing will be harsh and we are supposed to protect the egg on the actual rocket. After, I put 1 or 2 small rocks into the nose cone before gluing it on because then it will have a high center of mass which will make it actually fly like a rocket. I never flew my rocket because I was away on the day we did, and I did not make any fins as I was away for the previous days as well.
Here is my prototype rocket;

The Construction Process for the Rocket:

Materials

· 2L empty plastic bottle
· Cardboard sheets
· Box cutter
· Hot glue gun/Glue
· Black/Grey Vinyl sheets
· Scissors
· Foam cord
· Water
· Egg
· Sponge
· Cotton Balls
· Bubble wrap

Steps:
(Before, all of these steps make sure you have the vinyl color of your choice onto the cardboard before cutting it off)
1. Firstly, gather materials for building pop bottle rocket
2. Measure the amount of the cardboard sheet needed to wrap bottle
3. Cut cardboard sheet using box cutter
4. Wrap cardboard sheet around 2L bottle and apply hot glue on edge of cardboard sheet so that

There were not as many steps as I thought there would be involved in building the bottle itself. First I emptied out two two liters of pop. I then cut off the tops of both bottles, and threw out one of the bases. In the leftover base, I poured water, aquatic gravel, and a fake plant for the fish. I then put the fish in it’s new happy home. In order to feed him, I cut out a flap leading to the water that I can put fish food in. After that, I began working on the top layer. I placed one of the tops, with the cap still on, about half an inch into the original base. I taped it securely into the base, to ensure that the whole upper layer would not crush the fish. Then I put my plants into the half-built top layer. After that I placed my second bottle top on top of the base, creating another funnel. I taped the top securely on, finishing the bottle. I can screw and unscrew the cap whenever I need to give the plant water.…

The central conflict is that he does not feel the same since he has come back from Vietnam. I would say there are two instances that he best describes this problem. "I still hadn't told her I felt I'd left part of myself in her country." (88) Another moment was at the very end when he imagines the faces of the dead from Vietnam on his way to L.A. I think that the whole story builds up suspense by the way he dances around the problem and never talks to Lily about Vietnam. He also mentions that since he had been back he and his friends had not even acknowledged that he had been there. I think that this is very significant in identifying that what he had to deal with in Vietnam has scared him. I would almost identify Komunyakaa with the machine as he talks about working. I get the sense that he is just trying to make it day to day and that his experiences in Vietnam are holding him back from really living. I think that eventually Komunyakaa decides to move forward by going to school because the alternative seems to be him living out his days in the drooling factory.…
