Karin does not learn from Lars' mistake
Here's a description of the contestant's attempt. Someone's probably working on collecting some images to illustrate it.
Olli tricks Karin into going second, by posing the contestants some simple mental arithmetic, which she answers first. Karin alternatively stacks eight cups and eight saucers on top of one another, on the table, apparently not having learned from Lars' mistake. However, she fails even earlier than Lars, as the stack topples before she even tries to pick it up. She is therefore eliminated, and earns joint last place with Lars.
