When it's time to show your kids how to fold a humble piece of paper into a soaring jet, don't stumble around and hastily construct one from the poor memory of your youth — one that takes a disappointing nosedive as soon as it leaves your fingertips. Instead, teach them the art of making a plane that can truly go the distance.

The three designs below are tried and true (you wouldn't believe some of the science behind paper airplanes) and are perfect beginner, moderate, and expert level models to play with. They go in order from easiest to hardest, so there's something for every age level — including adult; don't act like you're not going to try these out in the break room.
