(the net must not be hung up yet in this exercise!)
Divide all children in pairs and each child lying on one side of the field. The children on side 1 lie on their stomachs and the children on side 2 on their backs.
All children from side 1 run to the other side and lay down next to their partner on their back.
As soon as this is done, the partner of side 2 can run to the other side, quickly lie down on his/her belly, touch the ground with his/her nose and run back to his/her own place. There lie down again on the back
The child who lies on the ground on the back must now return to his/her own place.
