The Best Hack

Fold a single piece of paper down the center, length wise. Open it up, and fold two corners from one short side to the center, so that the short side is parallel to the center line. Fold the two corners this creates to the center in the same manner. Repeat this once more, but folding in the opposite direction. A section of the structure should create a T shape. Throw the piece of paper with the smallest end facing forward, and it will glide.

This is the most elegant repurposing of an everyday object I know: the paper airplane.
