A bottle rocket that I designed in a group with three other classmates; Shane Hindle, Josh Gardner and Rafay Ahmad. Each team used a two litre bottle as the base of a rocket that we filled with water to a level we chose and pressurized it, then laucnhing the rockets. Each team needed to design a set of wings, a nose cone and a holder for a ping pong ball to sit on and break the wind when the rocket is flying. Shane was in charge of designing the Cone, Josh made the wings, I finished the ping pong ball holder and assembled the entire rocket, and Rafay... Well, he ws there. Overall, the rocket was filled halfway with water and flew the second highest of any group in the class, but unfortuntely was destroyed when it hit the ground after it's first flight as it wet so high up... May it rest in peace.
