Fascinating Guiness World Records for Swimming, Pools

The Answers to All Your Bar Bets and Questions

As with any Guiness World Record, don't ask why. The answer is always going to be because. Because it's there. Because you, he, she, they or we can. It's part of human nature, spirit, competition, and, frankly, the reason the Guiness World Record exists. It's also a not-so-subtle PR method, a way of getting your name, company or brand on the map.

To satisfy those burning questions:

Where is the world's largest swimming pool? How many people wore swim caps together at one time, and What was the largest number of people to perform a synchronized swimming performance?
Who knows? Maybe these will give you inspiration to break some other as-yet-unbroken record.
