What makes a paper airplane?

Answer 1

First, fold a A4 piece of paper in half and open it up.

Then get the top two corners and fold them so they make triangles, one of the sides touching the center crease each.

Afterwards, fold it in half, following the crease.

And then, it will start taking shape. On one of the sides, fold the corner from the triangle to the center crease and do it again. Do it on the other side too.

Then, hold the layer of paper in the middle and stick the other two out.

Throw it in the air to see how far it goes!
