Nikki has excellent foresight

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

Nikki is either not bothered by the lock on the fridge, or did not immediately notice that the fridge was locked, after reading the task. Off-camera, she goes to the shed and comes back with a lacrosse stick. She then reveals that she has had the key in her pocket the entire time, and simply unlocks the fridge, giving her nearly the full 20 minutes to complete the task. She uses the lacrosse stick to throw her milk cartons. The first misses, and nearly hits David. The second gets trapped in the lacrosse stick and stays there during her second and third attempts. She manages to use the lacrosse stick to get a carton of milk into the fridge while standing directly in front of it. The carton bounces out, but Nikki points out that a few drops of milk had remained on the shelf. She finally abandons the lacrosse stick and underhand-throws a carton towards the fridge. The carton hits the ground in front of the fridge, and rolls under the protruding crisper drawer, which is counted as successfully getting the milk into the fridge (it’s likely some of the milk from that throw also splashed into the fridge). With a distance of 9 metres and 80 centimetres, Nikki earns fourth place.
