Karin makes a stack

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

Karin decides to use a small book as the base of her stack, and asks Olli to stand on it. She then ascends a step-ladder, and climbs up to stand on Olli's shoulders, becoming the top item in the stack herself. At the moment of measuring, she lets go of the bannisters she is holding onto for support, so that her stack is free-standing. She neglects, however, to notice that multiple parts of her and Olli's bodies are narrower than the book, including her own upstretched arms and hands. In the studio, it is confirmed that the narrowest point of her stack was at the very top, but Olli charitably measures it at between 1 and 2 millimetres. She therefore earns fourth place in the task.
