Paper planes are the most tragic of toys: they soar, but only ever so briefly, and then they crash, crumple and die. Your hard work: ruined. Your flight, over in disaster.
When actually, it turns out there is a way to resist the inevitable rush of tragedy - at least for a little while. ViralVideoLab has a new clip in which they explain how a paper airplane can be made to fly forever, just by using a hairdrier, good aim and patience.
It's obviously a little dangerous for small children, so take care if you try it at home. But it's a neat trick if you can get it to work.
