The water rocket bottle we worked on was very fun, what I leaned is that during the launch process, when you pump air into the bottle the air moves to the top while it pushes the water to the bottom. During the design process we made had to make the water bottle rocket we made it out of a regular bottle. But before we ever made the bottle rocket we had to brainstorm the ideas for the project. When we finally got down to work we had to cut another bottle in half to make the top portion of our rocket, I had to hot glue the wings on to keep them installed them on the outside of the bottle. Then we made parachute out of a ping pong ball, we had to glue yarn strings to the ping pong ball and used a tissue paper roll to the top part of the rocket.
