Wonders of Water at the Olympic Games

The past twelve days it has been exciting to watch the best swimmers in the world compete in the London Olympics, setting at least nine new world records. And the most decorated Olympian in history made his emphatic mark in the pool.

These athletes make it all look so easy, but, in fact, they have to exert tremendous energy propelling their bodies through water that is 784 times more dense than air. The same is true for the synchro-swimmers, sailors, rowers, kayakers and those tigers of the pool, the water-polo players.
