Could physics have saved England's 2010 World Cup campaign?
In short: When Frank Lampard's shot hit the crossbar during the 2010 World Cup, the ball appeared to cross the line before bouncing back out. This video explores how the physics of ball spin could have changed the referee's decision.
In a high-stakes knockout match, a goal by Frank Lampard was disallowed because neither the referee nor the linesman believed the ball had crossed the line. While many argued for the implementation of goal-line technology, this demonstration shows how understanding the mechanics of spin could have provided a simpler answer. Andy uses a simple experiment to illustrate how the rotation on the ball caused it to bounce back out of the goal after hitting the underside of the crossbar.
