She's a real-life mermaid and world record holder!

I got a chance to sit down with Sara Campbell, who just made the incredible 314 feet dive straight down into Bahama waters...breaking the world record!

This 37 year old only took up diving a few years ago...and she held her breath for this amazing dive for 3 minutes, 34 seconds underwater! Sara wears a monofin, a single fin that both feet slip into, hence the mermaid effect. She stopped by the Inside Edition studios to chat about her amazing feat. What a neat lady! Needless to say, I felt very pale next to this tanned beauty. Sara said the majority of the dive is MENTAL...you have to believe you can do it. She says she feels this way about most things in life - believe it, and you will achieve it. What great advice. The story airs Monday and Tuesday, April 14th and 15th, on Inside Edition.
