This is a double-project, because each requires the scraps of the other. The origami airplane requires a square sheet of paper, and the ninja star needs the strip left over from turning a regular sheet of copy paper into a square sheet.

Both of these contraptions fly well if you take your time and make them carefully. Just watch yourself with the ninja star – it’s not only fast and furious, the ends are sharp and guaranteed to turn heads… and necks.
