Eva struggles to count the balls
Here's a description of the contestant's attempt. Someone's probably working on collecting some images to illustrate it.
Eva starts counting the balls into a separate bin, but also has Mark adding balls to the bin, and it's not entirely clear how effective the communication is on the running total. She then appears to get tired of the process, and for some reason suggests blending the balls in the food processor she is using a part of. She attempts to estimate the contents of the smaller basket using cubic multiplication, but neither she nor Mark can manage it. With under 30 seconds left on the clock, she desperately tries to return the remaining balls to the bin, but ends up tipping many of them back out onto the floor. Having failed to get them back before time runs out, Eva leaves the room, but then returns to estimate that there were 1,553 balls in the basket. Of course, she did not keep to the rules of the task, so is disqualified.
