Martha completely exhausts herself
Here's a description of the contestant's attempt. Someone's probably working on collecting some images to illustrate it.
Martha immediately enters the room and jumps into the bin, swimming around in the balls before using a metal bowl to scoop them out. Having almost removed all of the balls, she briefly starts examining the construction of the box, identifying that perhaps it could be dismantled to get the balls out quicker. However, she cannot figure out how to do this quickly, so instead persists with removing the balls manually and finishes, exhausted, after 13 minutes.
