Watch The World’s Largest Jenga Game Played With 5 Cat Excavators

Played with 27 giant, wood blocks (weighing in at 600 pounds each) and five Cat machines, this large-scale game of Jenga doesn’t defy gravity any more than the one you can play in your living room. This promotional ad for Cat must have taken real concentration and serious machine-operating skill to enact, considering that a total of 8.1 tons of wood isn’t going to budge by itself.

Don’t get nervous for the guy who directs the Excavators and Telehandlers used to precariously place this wooden blocks, though. Spoiler alert: He gets out of the way before the structure topples.
