Fern pursues a single strategy
Here's a description of the contestant's attempt. Someone's probably working on collecting some images to illustrate it.
Fern starts just dropping her toilet rolls whole, one-by-one, missing four times in a row (and exclaiming 'Oh nooo!' after each) before asking whether she should have some kind of tactic. Her fifth whole toilet roll bouces off the rim twice and then lands on the floor, and her sixth also bounces off the seat and misses. Her ninth roll lands directly in the toilet bowl, but the remaining three miss, and she runs out of ammunition with 13 minutes left on the clock. With her one successful shot, she manages to get 140 sheets of toilet paper into the toilet, and earns second place in the task.
