How to Make a Paper Airplane. No one knows who figured out how to make a folded piece
of paper fly, but airplanes just like this one have been plaguing schoolteachers ever
since! You will need A sheet of 8 1/2" x 11" paper and a ruler (optional). Step
1. Place the paper on a flat surface in front of you, as if you were about to write a letter.
Step 2. Fold the paper in half lengthwise. Make a crease, then unfold the paper and smooth
it flat again. Use the edge of a ruler instead of your finger to make your creases really
sharp. Step 3. Fold the top two corners down and toward the crease to form two triangles,
creating a point at the top of the paper. Press the folds flat. Step 4. Now fold the
two slanted edges at the top of the paper in so that they also run along the middle
crease. Step 5. Fold the entire right side of the paper over the left side (along the
middle crease), so that all of your new folds are on the inside. Step 6. Fold down the top
folded edge on one side so that it runs along your original middle crease. This will create
one of your wings. Step 7. Flip the paper over and repeat, folding the slanted edge
over to meet the middle crease, forming your other wing. A little weight at the front of
your plane can help it fly farther—try attaching a paper clip to the nose. Step 8. Unfold the
wings slightly upward, and you're ready to for takeoff. Did you know The longest distance
flown by a paper airplane indoors is 193 feet—which is farther than the first flight made by the
Wright brothers!
