Lars transports a leaf
Here's a description of the contestant's attempt. Someone's probably working on collecting some images to illustrate it.
Lars pulls a very small leaf off of a nearby plant and lifts that. He is extremely pleased with himself, after opening the second task brief, remarking that he has been "brilliant", and thus coining the episode title (note: he also makes two further references to how brilliant he has been during the task). He finds a bicycle in the garage, and uses that to transport the leaf away from the house. Having reached a more populated area, he finds a taxi to drive him even further away. In total, he manages to transport the leaf 3.9 kilometres, placing second.
