Einar builds an effective flour pipeline
Here's a description of the contestant's attempt. Someone's probably working on collecting some images to illustrate it.
Einar realises that he can leave the terrace if he doesn’t take the flour with him. He uses the grill and an umpire’s chair to prop up some pipes between the terrace and the bowl. He then puts some flour in the pipe, and uses a garden hose to flush the flour all the way through to the bowl. He ends up with 6 kilograms of flour in the bowl, and earns second place.
