Last night, Tom Daley made the first dive from the London 2012 Aquatics Centre in front of the world's media.

It was to mark the beginning of the one year countdown to the Olympics.

Tom finished the dive safely and described the diving pool as "cold"!

But he reckons the atmosphere in the massive 17,500 capacity arena will be "awesome".
