Chain Reactions Stepping His Game Up A ping pong cannon, a giant egg, and massive, car-sized tumbling dominoes are the stars of Tim Shaw's unbelievable experiments. Tim steps up this childhood pastime of aligning dominoes. Skewed Domino Effect Will this line of dominoes be able to generate enough force to knock the car down at the end of the line? Achieving New Highs Tim demonstrates an unusual feat of physics. Chain On The Loose Tim explains the science at play behind a rolling chain. Chain Gang Tim explains how tension and centripetal force work along the chain. Great Balls of Fire This modest ping-pong will be shot out of the white vacuum canon. Serving Up Fast Balls This isn't your average game of ping-pong! Tim has lined up this assembled vacuum canon to fire ping pong balls towards a ping-pong bat, but how powerful is the vacuum's serve?
