Martha makes liberal use of parcel tape

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

Martha pulls the mailbox out of the ground and lays it across the entrance to the low fence around the caravan as a somewhat ineffective barrier. She then enters the house through the back door and locks it behind herself, before placing obstacles in front of every doorway in an effort to slow Olli down. She also uses parcel tape to loosely secure the sliding interior doors, and to create a sticky web to block his approach to the stairs. She also sets up a garden hose, taping it to the top of a table tipped on edge, pointing down the steps that Olli will be using to enter the back of the house. However, she forgets to actually turn on the water before he begins, so he is easily able to get past the obstacle. As Olli sets off on his walk, she flings balls at him as a distraction, which appears pretty ineffective. Olli uses a thin decorative metal candleholder to break the tape holding the sliding doors closed from the other side, and continues on his journey, ducking under the parcel tape web and reaching the B on the balcony after 3 minutes and 29 seconds. Martha places third in the task.
