Paper airplanes - Fold the best paper airplanes!

The Tumbler

1. Take a sheet of thin paper, about 1 inch by 5 3/8 inches or a thicker sheet about 2 1/2 by 9 1/2, and fold it in half.

2. Now, carefully fold and unfold (crease) a right angle triangle and then reverse fold (sink) it into the center. The bottom side of the triangle should be about 3/5 of the bottom width.

3. Fold down what will become the "wings".

4. And open out fairly flat (but don't flatten out the creases very much).
