Einar passes one long object through an inner tube
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 make a really long object, which will be easy to pass through the tube. He collects a variety of long objects and tapes them together to become a single item, then passes this item through the inner tube. He earns second place.
