Neel creates a domino effect

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

Neel decides to build a domino course in the house. The course consists of Mark dropping a tennis ball from his mouth, which rolls down a slide and knocks over a path of large dominos, which push a ball off of the table to land on a jack in the box with Lasse’s face taped over the clown. Neel earns second place.
