Take your piece of paper.
Make it into a square. If you don't know how you can look at my other guide "How to make a square out of paper without scissors."
Fold the paper in half and unfold it. This just makes a guide for the next step. You can skip this step if you want to.
Fold the corners down like you would a regular paper airplane.
And there you have it!!! A paper airplane that flips in the air!!! :)
