My idea is more of creating an endless loop. A duckling will alway follow either its mother or another duckling. By scaring the mother she turns around and you create the first part of the loop. If you take away the mother in the right moment, the first duckling will see the last duckling and follow it. So the loop is closed. After seeing this comic I realy would like to test it in reality. But I think the sound of the mother will ruin everthing (shout out warnings).
