Watch: Don't try this at home! Man crashes down - and out - of elaborate backyard water slide
The recent hot weather has led to many back gardens being transformed into makeshift waterparks.
But the safety requirements of a paddling pool and a jacked up hose pale in comparison to this elaborate water slide.
David Salmon found out just how dangerous water sports can be when he sailed right out of the open air slide built at a private home in Austin.
The Texas man's 10-15ft fall on to a rocky cliff was captured on film by one of his friends - who was reportedly too far away to save him.
According to Fox 7, Salmon suffered a broken arm, fractured ribs and cuts on his back in the fall.
But he managed to take to social media to let his online friends know he was taking it all in good sport.
“Too dang old to be going down water slides,” he posted on Facebook.
