Now that those warm days at the lake have passed, people are updating their YouTube, Twitter, and Facebook pages with videos of their proudest summer stunts. Some include inner tube rides that end in nasty wipeouts, others show error prone attempts on the slip and slide, and more impressive clips show high dives off cliffs. The video above includes all three on an extreme scale, thanks to a human slingshot that obviously took some time to put together. Let's just say we don't advise such stunts, but if you want to really impress your friends on social media next year, you might have to up your game.
