Einar's box of concrete

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

Einar found the biggest shoes he could find (Timberland size 53) and then filled their box with concrete, and painted it blue. It weighed about 55 kilos. He had to keep it outside to dry for three days, using umbrellas to protect it when it was raining. Atle claimed the task could not be solved more ‘concretely’ than that, and Einar earned first place.
