The players form two pairs.
Everyone raises his dominant hand, that is, the writing hand, and then puts it on his back.
From now on, the two people will no longer be allowed to talk to each other.
Now the couples have 3 minutes to build a paper plane together.
The aim is for the paper plane to fly as far as possible.
After the 3 minutes, everyone line up and the paper planes are launched one after the other. The team with the furthest plane has won.
