Paper Plane

We need to make a paper plane that can fly stably without rotating.

A piece of A4 paper, a ruler, a pen.

Firstly,take out a piece of A4 paper and fold the paper in the half as it’s shown in the fig.

Then, fold the paper in the diagonal to let the upper edge coincide with the middle line.

So is another side.

This step must be done carefully to make sure the both sides are the same,or the final plane will rotate.

It’s similar to the step 2, just to let the upper bevel edge coincide with the middle line.

Then, fold the paper in the half as it’s shown in the picture, and draw a parallel line which is 1.5cm from the middle line.

Fold over the wings through the line.

So is another side.

This step must be done carefully to make sure the both sides are the same,or the final plane will rotate.

Finally,draw a parallel line which is 2.5cm from the top, like fig.6.

Then fold them over.

This step is to make the plane flies more stably.

And it’s done.
