Lidija reversed film
Here's a description of the contestant's attempt. Someone's probably working on collecting some images to illustrate it.
Lidija understands the task. Her film shows Luka entering the room and plugging in a vacuum cleaner before handing it to Lidija. Lidija uses the vacuum cleaner to blow out powder to spell 'Direktor Svemira' on the floor. It's not noted in the studio, but for the most part, Lidija's footage even gets the line order correct for most of the letters (for example, the left line of the 'K' shows up before the two diagonal right lines, and she writes the V from left to right). In the studio, Luka reveals that Lidija had titled her film 'Stardust'. She wins the task.
