How to Make an origami ninja star (shuriken) out of paper

Shuriken are the ancient Japanese weapons you've seen ninja warriors use in the movies. Their name literally translates as "sword hidden in the hand". In this tutorial you'll learn how to make a shuriken out of paper in a few fairly simple steps. But while this throwing star isn't as deadly as a metal version, it has sharp edges and it is potentially dangerous. Be very careful about where you throw it, and never throw it at people or animals!
