Julie finds the answer, but misses one tiny ball

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

Julie reaches down into the basket and stumbles across the small box, hidden inside the smaller basket within. She empties the contents of the box (a handful of tiny balls) and finds the number 1,598 written inside. With plenty of time remaining, she collects all of the balls that have fallen out of the basket and returns them, and then returns what she thinks is all of the tiny balls to their box, and replaces that. Having made her formal 'guess' of 1,598 balls, it appears that she has clearly won the task, and is led to believe that this is the case, in studio, until Mark 'discovers' a second clip of her attempt on his tablet. This clip reveals that just one of the tiny balls had been left on the floor, and had actually been underneath her foot, before she walked away. Julie is thus also disqualified from the task.
