Team fails to build largest chain reaction machine

Associated Press

A team at the Michigan Science Center in Detroit has fallen short of building the world’s largest chain reaction machine.

Lead builder Steve Price says some sections failed, which meant there weren’t enough completed steps to break the record.

The machine activated Saturday featured about a half-million objects, including about 200,000 dominoes and other components including ping pong balls, Hot Wheels tracks and blocks.

Organizers say the current Guinness World Records mark for a Rube Goldberg machine had 300 steps. Price says his machine had between 400 and 500 steps but the number likely fell below 200 after the failures.

Price says he’s still proud of the team’s effort and the scale of what was built.

The machine was called the “Zeal Credit Union’s Incredible Science Machine.”
