Water Bottle Rocket With Parachute

This website gives easy to follow step by step instructions with pictures on how to build a water bottle rocket with a side deployment parachute. The site also lists all of the supplies that are necessary to successfully construct the rocket as well as a brief overview of the project. I chose this website over a lot of the others that I found, because it featured a parachute in the design. The parachute, I believe, will keep the rocket in the air for a longer period of time. Since the rocket has to be in the air for a minimum of 10 seconds, I figured that suspending the rocket in the air after it reaches its peak with a parachute is a wise idea.
