The video, taken on Instagram, shows two swim-wear clad people by a swimming pool.
They are both using a swing on the side of the pool, using their legs to get momentum.
The man on the back forces the swing forward while the woman clings on, facing the pool.
Suddenly, the swing goes almost vertical and almost throws the pair of them out.
What happens next is hard to believe.
The woman in question is Rhiannan Iffland, a two time Redbull Cliff Diving champion from Australia
The woman in front then throws herself off the swing and into the air.
She launches into the sky above the pool, before attempting a number of spins.
After numerous flips in the air, she quickly falls back down to the pool and lands in a perfect dive.
While shocking, it isn’t just a normal swimmer who managed the fantastic feat.

Viral video: The bikini-clad woman attempts a very scary dive trick
The video, which has had over 7,700 views on Instagram, shocked users.
One wrote: “Beautiful tuck, looks like a blast!”
Another remarked: “How sick!!”
Others were reluctant to ever try that for themselves: “That looks so fun! I reckon I would hurt myself within the first 5 mins.”
While graceful, dives don’t always go according to plan.

A different video captured a young woman in a bikini trying to jump from a cliff.
She begins well with a star jump, but it quickly goes wrong as she lands in a ball in the water.
Another woman on holiday attempted a much more tame jump from a diving board in a swimming pool.
As she runs onto the board, she throws her arms in the air to dive as it snaps.
She is thrown into the pool, looking back in confusion.
