This is how to make a really cool paper airplane. This is a distance flyer and you really need to be out in the open to get the full effect. That said, for some reason it can be kind of hit and miss so try it a couple of times more if your first one doesn't work so well.
(1) 8.5'' X 11'' copy paper
Step 1: The Preliminaries
1. Fold the 8.5’’ X 11’’ copy paper in half length-wise so that the two 11-inch sides are touching each other after folding.
2. After folding, unfold paper and flatten crease so that the paper lies flat on working surface.
