Martha uses a dustbin lid
Here's a description of the contestant's attempt. Someone's probably working on collecting some images to illustrate it.
Martha doesn't understand at first that she has 10 minutes to prepare herself, before the water turns on, thinking that she must just stand and wait for the entire period. She then tries to manufacture a funnel for herself by forcing a nail through the base of a stainless steel bowl. After this fails, she tries the same with a plastic bucket, succeeding only in completely breaking the bottom of the bucket with a mallet. She ultimately has to resort to running around in the garden with a dustbin lid, trying to catch the water from the sprinkler. She does manage to collect 16ml, though, earning her third place after the disqualifications of Kristoffer and Live.
