Ida scrapes up as much as she can
Here's a description of the contestant's attempt. Someone's probably working on collecting some images to illustrate it.
Ida cuts a hole in the sealed end of the tube with a knife. After managing to return the majority of the caviar back into the tube, she uses the knife to scrape up any remnants and scrape it into the tube, fearing that someone else might return just 0.1 grams more than her. She earns third place with 253g, losing second place by just one gram, to her annoyance.
