There's a guy in MI that builds model skyscrapers with jenga (wooden) blocks then has people pull out blocks until they collapse.
His Leaning Tower of Pisa was rigged with a wire around the supports at the bottom. When a reporter circled the tower dragging a microphone cable, they yanked the wire making it look like the reporter accidentally toppled the tower.

Check it out here and here.

Oooooor you can go over to this thread
