Dubbed by its makers as the “Backyard Waterslide of DOOM,” this group of fun-loving people built a killer backyard waterslide complete with a loop-the-loop. Watch as two people slide down simultaneously at opposite ends without ever making contact.

A woman, decked out in a crash helmet, slides down from the left at high speed, while a man slides down from the right. While the woman goes around the loop, the man shoots right through and lands quite hard in the small inflatable pool. Although it does look a bit dangerous, you can’t deny it looks fun!

It may have taken them days to design and build, but for the few seconds of backyard thrill, this waterslide gets our vote of approval.
