Pro golfer Bubba Watson 'launches hovering golf cart'

US professional golfer Bubba Watson has apparently collaborated with sports clothing firm Oakley to build a hovercraft golf cart.

In a video posted online, the US Open winner can be seen cruising around a golf course in the hovercraft and even floating over the surface of a pond.

A pundit, identified as hovercraft expert Chris Fitzgerald, explains how the pressure exerted by the cart is 33 times less than a human foot, making it perfect for putting greens.

The fact that the video was uploaded a day after April Fools' Day has aroused some suspicion, but USA Today insists it is genuine.

US pro golfers swap irons for bling in charity effort

Four US golfers have swapped their irons for gold bling in an effort to raise money for charity.

The winner of last year's US Masters, Bubba Watson, has teamed up with fellow pro golfers Ben Crane, Rickie Fowler and Hunter Mahan to make a spoof hip hop video.

The self-styled 'Golf Boys' are aiming to repeat the success of their 2011 single 'Oh Oh Oh' which was viewed almost six million times on You Tube.

"We are in a truly unique era," Crane told the PGA Tour's official website. "I love that we can goof off on YouTube and help people across the world. I'm all in for that."
