Audri, a first grader, is a curious little fellow who's fascinated with Rube Goldberg machines, those contraptions that deliberately complete simple tasks in a very complex fashion, usually including a chain reaction. (One of the more famous examples might be Pee Wee Herman's creative breakfast-making device in "Pee Wee's Big Adventure.")

So the 7-year-old decided to build his own -- a Rube Goldberg machine "monster trap," that is -- and document each part of the apparatus with help from his mom. Very scientifically, he makes predictions on how many aspects will fail and succeed.

On the fourth try, his design works and the kid adorably jumps for joy at the end as his homemade invention turned out to be a succcess. Audri also leaves us with some words of wisdom in the end: "If you don't succeed, try, try again."

Viral video music stars OK Go, whose song plays in the background, also gave a thumbs up to the boy's successful design.

"First grader Audri saw 'This Too Shall Pass' and made a Rube Goldberg machine of his own," the band wrote on Facebook. "Wow."
