1. Make your own Rotocopter
To make your rotocopter, you will need a template and one paper clip.
Start by folding the X panel back along the dotted line.
Then, fold the Y panel back along the dotted line. Press down on the creases.
Fold the Z panel up along the dotted line and press down.
Next, fold Wing A down along the dotted line and press down.

2. Then, fold Wing B back in the opposite direction and press down.
Lift the two wings up so that they stick out.
Finally, put a paper clip on the bottom of your rotocopter, on top of Z.
Your rotocopter is ready to fly. Drop it and see what happens!
