Consider yourself ballsy? Love a good adrenaline rush?
Well, think again.
'Cos even the ballsiest of ballsy will find this terrifying.
You can officially zip line off the second floor of the Eiffel Tower, 115 metres above ground, for half a mile, at an average of 90km/h.
The zip line has been set up by Perrier to celebrate the French Open - and even watching this video has us scared shitless.
Le Perrier Smash runs from June 5 to June 11.
