Your airplane is done. All that is left now is to fly the plane. Hold it on it's underside, and give a quick strong throw and watch it glide!
Step 7: Add Paper Clip
Most of the airplanes weight will be in it's nose since most of the paper was folded up there. To keep the plane in the air longer instead of having it do a nosedive, put a paper clip somewhere near the back of the airplane to balance out the weight a bit.
