We have learned that rockets can be used for different purposes and can vary in shape and size. We learned that rockets can be fueled by different types of materials, everything from simple hydrogen to electrons. Rockets can also vary in complexity, everything from the simple solid tube of gunpowder to the complex maze of pipes, valves, pumps and wires that make up some of the liquid engines. Most people would be able to build a simple rocket at home, I wouldn�t recommend it unless you have experience dealing with explosives, but it could be done. Rockets have helped us get to the stars and and see our planet in ways that people in the past would never though possible. I hope you have learned that rockets were a necessary step in our evolution in order to get where we are today, and will continue to aid us in future.

In conclusion the rocket has been an invaluable technology to the human race and will continue to be so for a long time to come. They can be used for transportation, exploration and mass destruction, hopefully that we will learn to forget the latter usage and concentrate more on the former two.

"Only two things are infinite, the universe and human stupidity, and I'm not sure about the former."
