Construction of ROCKET (on land)

Putting the two bottles together was a challenge that we faced when constructing our rocket. It was hard getting the right cut and fitting them in together. Deciding the amount of tape we used was a big challenge because we wanted it to be sturdy but not heavy. We were also worried about the alignment of the fins, determining whether it would fly strait or not. After figuring it out we are confident that our rocket is proportional and the right weight for a successful launch of at least 10 seconds.
