The new series kicks off with our barmiest challenge yet: to build a machine that will fire an ostrich egg as far as possible and bring it back to earth in one piece. The machines must be mobile so that - if the eggs survive intact - they can be wheeled to the landing spot for another attempt. Each team is given three eggs and the winner is whoever has travelled the furthest after three shots.
