Marko eventually finds balance

Here's a description of the contestant's attempt. Someone's probably working on collecting some images to illustrate it.

Marko immediately runs off after reading the task, and returns with several long pieces of guttering. He runs them down the hill and into the bathtub, but immediately realises that the final piece arcs uphill, into the bathtub. To solve this issue, Marko attempts to raise the guttering with planks of wood, but he has difficulty getting everything to balance. Eventually, he does manage to raise his channel enough to allow water to flow into the bathtub. When the water starts, Marko holds a dish over the hole, trying to divert the flow of water into his channel. He is eventually able to get a small stream of water into the guttering. Marko moves 0.2 litres of water, which earns him fourth place.
