If you're afraid of heights or the thoughts of jumping off a very tall building makes you queasy, look away now.
A group of base jumpers and parachutists tested out one of the highest urban ziplines in the world, located in Dubai.
The Princess Tower, which is the second-highest residential building in the world, has been the site of over 550 base jumps since the programme launched.
This footage, captured on GoPro cameras attached to the jumpers, make it look like a trailer for a pretty amazing film.
Take a look. This actually made us dizzy looking at it.
