A Better Paper Plane
As a child, for some reason I really really wanted to make the best paper plane possible. I tried a lot of fancy designs, most of which were worse than the classic pointy “dart”. Nothing was better than one of the early ones I found, which in the classic form I learnt is made like like this. Fold a sheet of A4 paper lengthways, then unfold it again. With the valley side of the folded paper up, fold the corners of one end to the centre line created by the fold, so that they create triangles at 45 degrees....
