Using a 1/3 liter drink can, we fill the 1.5 liter cola bottle in steps of 1/3 liter and create marker lines.

Geert ready to pull the rope to which the nail is connected.

Retrieving the bottle.

Here you can clearly see the metal plate to which a piece of rope is connected. The metal plate is held in place by a nail on the bottom side of the plank. The rope ends in a loop.

Through that loop (the blue-white rope) runs another rope (the white one). The white rope is fastened to two nails in the side of the plank.

Fastening the rope to the nail. The second nail is behind Pieter's hand.
