Yep, Make an Airplane

This is a must.  Once you read this, you must take a sheet of 8 1/2 x 11 paper and make an airplane.  You will impress the kids in your life.  Heck, you'll impress yourself with the way this baby flies.

Directions:

1.  Fold a sheet of paper in half lengthways so you'll have a center line.

2.  Unfold and lay flat.  Now, fold each top corner in toward the center line.  You'll have a triangle at the top of your paper.

3.  Fold the triangle down, so your paper looks like an envelope.  You'll fold the paper down past the triangle you just made.

4.  Fold the top corners of your paper down again.  You should be able to leave the triangular point of the first triangle sticking out beneath your second triangle.

5.  Fold the triangle that is sticking out up over the corners to hold them down.

6.  Fold in half along the spine, leaving the triangle on the outside.

7.  Finally, fold the wings back on themselves, finding the halfway line carefully. 

Now, throw that baby!
