2. Your rocket will be filled about 1/3 full of water. It will then sit on the launcher with the neck down. Air will be pumped into it and then released. A poorly designed rocket will go about 25 feet in the air. A very good rocket will go well over 100 feet high. They fly very fast so good construction is necessary. 3.
