Anders creates a domino effect

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

Anders decides to build a domino course in the yard out of large objects. The course consists of Mark dropping an oil drum, which rolls down a slide and hits a wheeled toboggan, which pushes a bowling ball past a goal line. Somehow, the bowling ball passing the goal line is supposed to release some balloons. Instead, the bowling ball just rolls over the balloons. However, Anders realises that the only reason the balloons didn’t launch is that he was inadvertently stepping on the string. Anders earns third place.
