Paper Airplanes are a significant part of everbody's childhood, and although you may not have realized it when you were younger, there is alot of science behind the flaps and elevators some people build on their airplanes. After you read this instructable, the next time you see a group of people flying paper airplanes and they are wondering why their plane keeps diving, or shooting up, you will be able to pass on this knowledge to them and explain how aerodynamics works. In this instructable, you will: learn the basics of designing your own paper airplanes, learn why paper airplanes work the way they do, you will learn a few of my favorite paper airplane designs, and last but not least, HAVE FUN! Because of the ease of setup, and the simplicity of this project, I would highly reccomend building this with students or children. Enjoy!

Step 1: Materials
You will need...
* Paper (preferably 2-3 pieces of computer printing paper)
* An open room (it shouldn't have fragile objects, and preferably no wind)
* The ability to learn
Step 2: Building your test plane
We are going to have to build a test plane to demonstrate how to bend the wings certain ways to get different outcomes. To do so, you will need one of those pieces of paper, and the pair of scissors.
First, Fold the paper in half lengthways to make a crease, and then unfold it.
Next, fold down one corner down to the crease, and do the same with the other corner. (Look at the picture for help)
Step 3: Step 3:
Fold the whole top part down, so there is a triangle with its point facing down as shown in the picture. I know many paper airplane designs do not include this, but this plane works really well to demonstrate how the elevators work. Now, you will have to fold the corners down to the crease and make sure you make this crease is heavy.
